When Will Rattlesnakes Go Away To Hibernate? Details Based on Thousands of Rattlesnake Relocations

Posted on October 19, 2023October 19, 2023 by Bryan Hughes

It’s that time of year when every rattlesnake sighting prompts the question: when will rattlesnakes disappear for the winter? It’s a topic that causes some confusion with many people who believe that reptiles only want heat, and as soon as it starts to cool, they disappear entirely. But like many things with animals, the reality of the situation is much more complicated. Fortunately, after more than a decade of working with homeowners on conflict situations, during this time of year, we have the data to answer this question quite accurately. This observational assessment is based on the frequency, timing, and nature of the more than 15,000 snake relocation calls we have run since 2009.

Late October is peak time for rattlesnake encounters. This is completely normal. While there is no calendar for wild animals, there are some strong trends that are more or less true every year. Even though it’s still hot outside right now, we see no reason to believe this year will be any different. Here’s the timeline:

Throughout October, rattlesnakes are moving. By the third week of October, much of this activity takes place in a short window of time immediately after dark. This may only be an hour, where everything appears to move at once. Encounters with the snakes, may also happen in the early morning, as people see them resting in the temporary location they have selected. This behavior will reach a peak in the last days of October, through the first week of November. By the second week of November, even this behavior begins to wane. By the end of the second week of November, most rattlesnakes are where they intend to be for the winter and the encounter is driven by their traveling and mating. Behavior will have more or less ended. By Thanksgiving, any rattlesnake relocation requests we receive are snakes that are in garage, or other on property hibernaculum, indicating ingress has completed.

Late October rattlesnake encounters are perfectly normal

As days, go, shorter, and temperatures drop, usually, rattlesnake activity is going to change in a number of ways. First, although some may hunt and continue to do so later into the year, most are in transit. They are moving towards areas that they have selected to spend the winter. Some rattlesnakes like the young of the year or those who have been displaced by construction or other issues, may be in a wandering pattern, looking for a suitable spot. Others, maybe successful adult rattlesnakes that know exactly where to go, and they are moving in a straight line to get there.

Along the way, there may be conflict with humans. This could be, as the snake is crawling through a backyard and, spotted by the dog, forgets held up in a maze of block, walls and stucco. And increasingly, the overwinter destination itself may be on the property. This could be in a garage, under a shed, in the foundation of a home, under slabs of concrete, under air conditioning, or pool, equipment, and any number of scenarios.

The nature of these encounters can be different, because unlike those in the spring, where temperatures and day links were similar, the objectives of the animals may be different. Setting up ambush positions to hunt is no longer a priority, and rattlesnakes may be more likely to rattle out a person or a pet that discovers them as they are in transit. While in the spring time, most rattlesnake encounters at homes may be a snake soundly coiled in a corner, in this time of year it’s usually a snake on the crawl or moving across the surface. With winter, approaching, and the opportunity to hunt in the cool weather, drawing to a close, rattlesnakes are in conservation mode. Essentially, they have the food, energy and water that they have, and it’s time to get to a place for the winter to hang onto it. Remaining above ground, even in otherwise favorable conditions, has no benefit, and may only serve two accelerate the desiccation that may occur in an Arizona dry winter. Rattlesnakes in the low desert may even select overwintering sites that are cooler, to keep a lower, metabolism and slow, the loss of resources.

The fall is also mating, season, again. Wow, much of this behavior happens in advance of moving towards dens, it still occurs up until the end. This can mean that, in addition to traveling rattlesnakes, a homeowner can see pairs in courtship or mating. However, while this behavior is common, it does not seem to drive encounters the same way that it does in the spring time. In March for example if we find an adult female Western Diamondback Rattlesnake, we can often find males in the area searching for her. This is such a strong driver of encounters that in peak spring time, mating season, this might be something that we even expect. In the fall, however, this does not seem to be the case and courtship and meeting may be an aspect of opportunity as snakes continue to come together anyway to group social situations.

Rattlesnakes can still be encountered in the winter

Once snakes are in their dens, it does not mean that homeowners don’t need to think about them during the winter. Please note that I did not use the word “fear” there, as it isn’t necessary or helpful when all that must be done is to remain rational and, take minor precautions. This means that if you live in an area where rattlesnakes can occur, just do as you always would, and follow the basic rattlesnake safety measures you do the rest of the year. Don’t reach where you can’t see, always watch where you walk even on cold days and nights, use flashlights and wear shoes, etc. Just because rattlesnake encounters are much less frequent does not mean they don’t occur, in fact, they often do, so just stay sharp.

Keep rattlesnakes from using your property as a den:

Here are some things that you can do as a homeowner, often relatively easily, to reduce the chances of your property, becoming a rattlesnake den. If this is a concern, devote hey Saturday, and in most cases, you can be done in that time one.

Identify and remove any deep hiding opportunities. This might mean pavers stored along the side, yard, those cinderblocks you meant to do something with, but the project has stalled, the old pool toy box full of deflated floaties, etc. Any items that are stored, long-term and not disturbed can create thermal protection that rattlesnakes and other animals can use
Move the firewood stack to a different location. In fact, do this once a year. It doesn’t need to be far; you can just move it right next to the original location if you choose, but just make sure that it is not a permanent location. Firewood piles are a favorite for rodents and the holes that they dig can be used by rattlesnakes. We often are called to remove rattlesnakes from firewood piles during the winter, and simply moving them, seems to prevent that quite well.
Find and repair any openings into the foundation of structures. These do not need to be large openings, they can even be what look like in minor cracks, going up into the flashing, or a wall joint that has eroded or settled. This can also include sheds or other secondary structures, built on concrete pads that have rodent tunnels going under them or other openings. The quick fix is expanding foam, easily obtainable at any hardware store, while the long-term fix can be arranged.
Learn what a packrat (wood rat) nest looks like and destroy the ones you find on your property. Paquerette nests are favorite homes for rattlesnakes at any time of year, including the winter. Rattlesnakes live alongside these rodents in these often deep and well insulated spaces. To remove a packrat nest permanently, traps, and other rodent control won’t do the trick. Destroy the nest itself. You can do this by flooding it entirely with a garden hose several times, then using garden tools to remove and spread the surface debris and collapse all entrances. Repeat until it is no longer being repaired by the rodent. This single step may be the most important one in this list.
Repair any gaps in garage door seals or call somebody to make sure that gets done. If you see debris and dirt in the corners alongside the edges of garage doors, that means that they are not sealed and animals, including rattlesnakes can get in. You may also want to use this time to get to that long, awaited garage, clean out, and re-organization you wanted to do forever. Cluttered garage are great places for a rattlesnake to spend the winter undisturbed in safety and relative warmth, and they often do. Because it’s a long corners and walls, and reduce the number of hiding spots as much as possible.
Check the areas around seldom visited parts of the yard, like the pool pump, equipment, and air conditioning units. These are often mounted on concrete pads which rodents do you under to create spaces. These are also out-of-the-way locations that people don’t visit very much and as a result, the place where things like bricks and discarded pool toys end up being discarded. Clean up any of these items and fill or collapse any rodent holes going underneath.
If your yard has large and extensive tracts of low-cover landscaping, such as lantana, rosemary, and natal plum, consider upgrading to less rattlesnake-friendly plants. These popular landscape vegetation choices, often create inches of rotting organic material underneath while also retaining moisture We have removed hundreds of rattlesnakes from the situation at homes over the years.
If your property uses riprap, or other piled rock, as decorative or erosion control material, be cautious. The best situation in either case is that the rock is situated to be no more than one or two rock layers deep. This means that each rock in the layer is exposed to the sun and touching the ground. This is not necessarily a useful feature to be a rattlesnake if done like this. If the rock is several layers, deep, however, creating spaces and thermal opportunities within, rattlesnakes, and other animals will, of course find this useful, and perhaps no time more so than in the winter. If this rock area is made of piles of cantaloupe-to-watermelon sized boulders, and several feet thick, you can probably count on rattlesnakes using it. Of course, this rock may be in place for functional needs like erosion control, but if you have an abundance of rattlesnake visits throughout the spring, it may be worthwhile to consider other options
Be especially cautious, when pulling out items from storage that have been there for a long time without being disturbed. Specifically, holiday decorations. It is likely that your plastic Christmas tree and box of tangled lights have been sitting in the same corner of the storage shed without being looked at since you put them there last January, that means by the time you reach for them again in December, they have served only as a potential hiding spot for animals that doesn’t want to be disturbed. This is the same for Halloween, Thanksgiving, New Year, or whatever other holiday or overwinter things you might only look at once a year.
If there has been a dry period for more than two months, and rain comes, rattlesnakes will come out of the den to drink it. This will happen in any temperatures above freezing. That means that if it is the middle of December, and it’s midnight and 35° outside and it starts raining, rattlesnakes will be out. They won’t go far, maybe a few feet to a nearby bush for a little while, but this phenomenon is very reliable. Keep this in mind when going out to get firewood or other activities in such an event.

Stacks of firewood are often used by snakes and other animals as overwinter homes. This can be largely avoided by simply moving the location of the stack each year.

Rattlesnake spring emergence – ultimate guide for homeowners

Posted on February 10, 2022February 10, 2022 by Bryan Hughes

In the past few days, I’ve been to a multiple homes to catch rattlesnakes in garages. That’s normal and right on time. Which brings up the topic: when do rattlesnakes start moving again, and what should homeowners expect?

When will rattlesnakes come back? Our predictions, based on 11 years of relocation hotline activity:

Early February (you are here): Rattlesnakes will start to “stage”, or move closer to the entrance of, their winter dens. We will start to receive calls to remove small groups of rattlesnakes from garages, storage closets, sheds, and other out-of-the-way structures. Rattlesnake removal calls will frequently be multiple animals.

Late February: Rattlesnakes will start to appear out in the open near their selected dens. Garage removals will be more common. However, there will be an increase of calls to pool pumps, courtyards, and homes with rip rap and rock pile erosion control.

Early March: Snakes will start to make short movements from dens to hunt, drink, and engage in social behavior. They will be highly visible on the surface with peak activity occurring mid-morning before returning to the den or other nearby staging area. Mating activity is high, and multiple snake removal calls will be common.

Late March: Rattlesnake sightings will become common as they leave dens entirely. Peak activity will be between 3pm and 5pm.

April: Very high rattlesnake activity and sightings will be common. At this point they have entirely left the dens and sightings are more likely to be random encounters.

New! Rattlesnake Activity Forecast

We have a brand new Rattlesnake Activity Forecast tool! It’s based on real-time snake removal hotline activity. You can also check your zip code to see what kind of activity has happened in your area in the past.

Other good rattlesnake safety stuff to keep in mind:

Don’t worry. This is totally normal, even February sightings (don’t listen to the local news about “coming out early” stories).
If you’re a hiker or outdoorsy type, you’re still not likely to see a rattlesnake in February. Be more watchful and aware in March, however.
Now is the best time to get to any maintenance or prevention activities you have on your to-do list. Landscaping, debris removal, fixing the snake fence, having the dog trained … get it done before the snakes show up.
Rattlesnakes often den in the garage. If you are using these last mild-weather days to get to “that” side of the garage, use extra caution.

Educating yourself is the best way to stay safe and feel better about the whole situation

As with most things, fear of rattlesnakes is mostly in our heads. Not the fear itself of course, that’s a real thing, but most of what we believe about rattlesnakes as a culture is simply false. Down to the idea that they are aggressive, or territorial (in the way that people use the word) and more, most of us just haven’t had an opportunity to learn factual information.

If you fear rattlesnakes, spend an afternoon going through these resources and watch what happens 🙂

It’s Almost Rattlesnake Time Maintenance Check

Posted on January 16, 2021January 16, 2021 by Bryan Hughes

Starting in early March, rattlesnakes will again be a part of our lives in Arizona! While we’re excited, you may not be as much 🙂 Even when a rattlesnake fence is installed perfectly, things happen; rodents dig, branches fall, gates shift: we’ll make sure you’re good for Spring.

To make sure your yard is as good as it gets before things start getting all rattlesnakey out there, we’re offering a check-up and maintenance service to our Rattlesnake Fence customers through the end of February.

Inspection of rattlesnake fence, and up to 1 hour of repair and maintenance (materials included!)*
Full property inspection, checking landscaping, snake-hiding spots, to look for possible snake dens and advise on potential trouble areas
Removal and relocation of any snakes found, both in and outside of the protected areas
Spot-check garage, storage shed, etc (checking corners and walls for snake tracks and signs of activity)

Booking through the end of February for $200. (You don’t need to be there, but you’ll get more out of it if you are).

If you’re NOT a rattlesnake fence customer, we’ll add an 1-hour credit of labor and materials to an estimate for a new rattlesnake fence, good for anytime in 2021.

Email fence@rattlesnakesolutions.com or call us at 480-565-7824 to schedule.

* Repairs not related to workmanship or materials requiring more than 1 hour of labor/materials may be performed at additional cost, with your approval

Why are we still catching rattlesnakes in the winter?

Posted on December 3, 2020December 27, 2020 by Bryan Hughes

You may notice that our social media feeds are still full of rattlesnake captures and relocations, even in the coolest months of the year. Be assured: yes, rattlesnakes are hibernating (or brumating if you prefer) in the winter, roughly from November through February. However, as we’ve explained in previous winters, they can still be found from time to time on the surface.

The biggest reason you’ll still see so much from us is because we meter our content so that we don’t blow you away with 20+ posts during the summer days, and make you think we’ve disappeared during the winter. Every call is unique and interesting, with lessons and experiences that should be shared, so we space it out. That means that many of the photos you’re seeing in the winter may have been from calls we ran in October, etc.

There are of course snakes that are still active during the winter, both by their own choice, and not. We cover some of the reasons you may see one at your house during the cooler months in a previous post, named after the most common comment we see on photos of snakes found in the cooler months. “I thought they were hibernating!“

Why would rattlesnakes be active when it’s so old outside?

One of the biggest misconceptions about rattlesnake behavior is that they are driven purely by warm temperatures. While it is true that rattlesnakes, like all reptiles, are cold-blooded and depend on external forces to get warm, temperature is just one of many factors that determine whether or not they’ll become active.

Here’s a great example that happened recently. In 2020, the Phoenix area broke several records for the hottest, driest summer in recent history. When rain finally came to the valley after more than 100 days without a drop, it was on a cold December day.

With temperatures barely breaking 50˚F, why would rattlesnakes suddenly become active? Simply: they have to, or risk death. With minimal effort, I was able to find 7 Western Diamondback Rattlesnakes on the surface hoping for rain. The first was found at just 45˚F, and the last at 51˚F. Comparing field notes for the day with a couple of knowledgeable friends, who also knew to put on boots instead of sweatpants for the day, showed similar results. Rattlesnakes, even in relatively cold temperatures, were very active. When rain fell again for a brief period on Christmas day, again, it was not difficult to find a lone Western Diamondback Rattlesnake coming out for a drink.

All of these rattlesnakes were found on the surface in December, 2020.

Just because we see rattlesnakes in the winter doesn’t mean you will.

People are often surprised that we are still able to find rattlesnakes in the winter – in fact it’s probably why you’re reading this right now. If you’re not someone that wants to run into them out there, don’t worry: it’s very unlikely that you will.

Rattlesnakes that we find in the winter aren’t in the same situation that you’d find them during other, warmer periods. They’re not out moving large distances, tracking prey, looking for mates, or any of the other behaviors that most often result in an encounter. This activity is much more specific – just coming to the surface of their den, and back down again when they’ve gotten what they need. That means that if you’re hiking on a trail and not purposefully searching situations that seem likely to house rattlesnakes over the winter, you’re not likely to see them at all.

Which neighborhoods in Phoenix have the fewest rattlesnakes?

Posted on October 23, 2020October 23, 2020 by Bryan Hughes

If you’re looking to move to Arizona, this question may be on your mind. Rattlesnakes seem to be everywhere in the state, so where can you buy a home and know what to expect? Fortunately, rattlesnakes are creatures of habit and where they are found tends to be fairly predictable. This is our overview of what we know about rattlesnakes and where they can be in the city, and a new tool we’ll be using to help communicate this to new Arizona residents.

Check the rattlesnake removal records!

While we will never make any information about an address or community public, we do share information based on zip code. Our removal activity log is available to the public, and is now searchable by zip code. If you’re curious about an area, pop in the zip code and you can see what kind of snake activity has occurred there. Keep in mind that zip codes can be large, so what happens at one house could be literally impossible just a couple of miles away. However, we won’t get more specific than this only to protect the privacy of our customers.

The further you are from native desert, the fewer rattlesnakes are found.

Rattlesnakes are specialized desert reptiles, which means that they aren’t great at new things. While a Sonoran Gophersnake or Kingsnake might be found deep into the valley, making use of well-watered lawns and a growing roof rat problem, rattlesnakes are different. Without the presence of native desert habitat, rattlesnakes will not be found.

If you select a home on the interior of the valley, more than a half-mile from the nearest native habitat, your chances of seeing a rattlesnake in your yard are exceedingly low. That doesn’t bar a freak happening, like a snake that hitches a ride in a truck or someone releasing one, but those aren’t meaningful considerations.

The 5-year “Snakey” scale

The easiest way to look at it would be to use this general formula. It’s based on an estimation from our experience and data collected from relocation calls over a 10 year period. It’s not exact, but can be used as a general guideline that is accurate enough to help make home-buying decisions. If you want to go deep on a lot of this, here’s peer-reviewed research using our relocation data to shows some of the reasons how and where contact zones occur.

The scale I will use here is how many rattlesnakes a homeowner may encounter per 5 year period of occupancy. For example: a score of 1.5 means that a homeowner can expect 1.5 rattlesnake encounters per 5 years of occupancy.

Score: 4 on the Snakey Scale. From the nearest native desert habitat, the first row of immediately adjacent homes has the highest chance of encounters, at greater than 100% chance if occupied per 5 years. This group includes, specifically, homes found at the corners or street-ends, where the highest rate of encounter occurs. Homeowners in this situation should to see a rattlesnake about every year or every other year.

Homes on the corner or end of the street, closest to direct access to native desert habitat, have the highest rate of encounter. Generally, each home or street from there decreases the rate of encounter.

Score: 3 on the Snakey Scale. From there, the second home or row (across the street) has a pretty high rate of encounter, but not nearly. Rattlesnakes tend to stick closer to access points. While they may be more inclined to just pop around the corner and stick to the wall, we nearly as often see them use the entire side of the first house into the second yard, and across the street as well. Homes in this situation will likely see a few rattlesnakes in a 5 year period of occupancy.

Score: 2.5 on the Snakey Scale. Any home in the first street row backing up to the desert. The likelihood in these instances is that the snake could come from both sides, regardless of the placement of the wall. Fortunately this can be easliy fixed, which may dramatically reduce that figure.

Score: 1.5 on the Snakey Scale. Homes across the street from the row immediately next to the edge of the desert may expect to see 1 or 2 rattlesnakes in the yard during a 5 year time period.

As you go further from access to native desert, the likelihood of seeing a snake changes quickly. However, it’s seldom this simple.

Score: 0.7 on the Snakey Scale. Homes on the first 2 (or so) interior streets could encounter a rattlesnake at some point, but it’s also possible to not see one at all during a 5 year occupancy.

Something as simple as an opening, or a drainage “park” as we commonly see them in Arizona, can dramatically change things for the neighborhood.

Score: 0.3 on the Snakey Scale. Homes greater than 2 streets in from native desert habitat, but closer than 5 streets may see a rattlesnake in their yard at some point, but a slim majority will not.

Score: 0.1 on the Snakey Scale. Homes more than 5 streets in, but less than 10, from the nearest native desert habitat could see a rattlesnake, but it’s not entirely likely. If it is one, it would more likely be due to construction, displacement, or a wandering baby rattlesnake. Around 1 in 5 homes will experience a rattlesnake in the yard in a 5-year stay.

Score: 0.05 on the Snakey Scale. Homes that are more than 10 streets in from the nearest desert habitat will most likely never encounter a rattlesnake in their yard. However, it’s still a possibility, and homeowners should continue to be on guard and follow all of the available safety precautions.

Score: 0 on the Snakey Scale. Homes on the interior of the city, more than a mile from the nearest native desert habitat, have almost no chance of seeing a rattlesnake in the yard. Having to cross numerous roadways, a maze of walls and fences, and limited access would make it incredibly hard for a rattlesnake to find its way there. In addition, there’s probably just nothing there that the snake would want, so it wouldn’t be all that motivated to make the journey.

But of course, it’s not that simple. Rattlesnakes are part of a dynamic system.

It should be stated about using this method, too, that there are many variables at play that have nothing to do with location. This is just a general guideline that we use ourselves when evaluating a property for likelihood of rattlesnake encounters. They can usually be mitigated by preparation and snake fencing, and ongoing education. This is also not an indication of how many rattlesnakes actually visit the property, but of how many may be encountered. If you’re a gardener, have a dog, or spend a lot of time in your backyard, you can expect a greater rate of encounter than someone who seldom goes back there.

This is also specific to rattlesnakes. Each group of snakes will have its own scale, based on what it needs and prefers. However, since they’re not harmful, we’re just talking about rattlesnakes here. However, you can use the same guide to loosely estimate similar results for other species, with the knowledge that it’s an entirely different ballgame for more adaptable species.

Additionally, this is based on natural rattlesnake behavior and excludes factors like construction or artificial placement, botched relocation jobs from the fire department, and other activity that more or less isn’t what a rattlesnake would choose to do. This list should not in any way be taken as a guarantee that you’ll never see a snake if you follow these general guidelines.

Most of the time, snakes like this Western Diamondback Rattlesnake use places like this because of easy access and provision of resources. But, as with most things, there are always exceptions to the rules.

How do I know if it’s native desert, or where this scale should start from?

That can be tricky, since neighborhoods are not so black and white as described here. For instance, a 2-acre patch of desertscrub a couple miles into the city just doesn’t have the same quality or snake-carrying capacity as untouched saguaro and Sonoran desert at the edge of the valley … so be subjective.

A good rule of thumb: if you see cactus that wasn’t planted there by someone, you can count on that as being native habitat, and rattlesnakes probably live there. Especially with the presence of rodent holes, you can count on there at least being a strong likelihood of rattlesnake presence.

Watch the washes!

One particular feature to watch for are washes. To our friends moving here from outside the desert southwest: a wash is our word for “stream” or “creek”, or basically a drainage without water in it for most of the year. These areas are one of the most important features for rattlesnakes of most species, and much of their activity is centered around them. Think of washes like desert highways, where animals can travel, find food, and generally find quite useful.

In most of the neighborhoods at the edge of the desert, there are washes that snake deep into the interior of the community. This can’t be avoided – these washes are natural waterways and necessary to prevent flooding and other issues. However that does mean that these homes have a higher saturation level of contact with natural desert habitat than other neighborhoods might. In some areas, washes are common enough that there really aren’t any homes found that don’t score relatively high on our Snakey Scale. If you’re overly concerned with rattlesnakes (or snakes in general, really) the further your new home is from a wash, the better.

But, should you avoid your dream house if snakes are present? No!

Just like moving to the northeast might mean that ticks are on your list of concerns, or moving to Alaska might put bears on your radar, Arizona has snakes. For the most part, you made a pact with Arizona the moment you decided you’re moving here: snakes are here, but they might be part of your life.

Proactive solutions, like having snake fencing installed, can still make it possible to live safely in any area of the state.

However, that isn’t nearly as bad as most people feel it is, and it’s generally easy enough to work with and be totally safe. You can have your dog trained, for instance, to avoid rattlesnakes, and you can make landscaping decisions that make the yard either inaccessible or unuseful for rattlesnakes. Additionally, you can help yourself feel much more comfortable around snakes simply by taking the time to learn about them. In fact, if you’ve read this far into this article, you’re probably the exact type of person who would continue that education and dissolve the fear of snakes.

If you find the perfect home, be careful not to rule it out because of snakes. For the most part, it’s just not the threat most people believe it to be. Even though the fear of them is certainly real, even that can be challenged and defeated in most cases. To either end, if you need any help to sort through it all, feel free to contact us about any area and we’ll tell you what we can. While we obviously can’t divulge any activity that’s actually happened at a house, we can advise on the general area and work with you to be comfortable … or to high-tail it to the center of the city!

End of Rattlesnake Season Checklist – 8 Steps to Make Your Yard Rattlesnake Free this Winter

Posted on October 1, 2020October 1, 2020 by Bryan Hughes

Summer has left us, and cooler temperatures are on the horizon. Yet, rattlesnakes are still incredibly active. In fact, the pre-hibernation flurry of activity means that encounters will be on the rise for a short amount of time.

In just a few short weeks, rattlesnakes need to eat and drink as much as they can, find mates, and travel long distances to their selected winter refuges. That can put them in conflict with people and pets, both on the trail and at home.

Here are some easy things you can do right now to get your property in shape so that any rattlesnakes that might be eyeballing your place as a winter den will keep on crawling.

1. Take care of that long-neglected landscaping project.

We all have one … that overgrown bush along the back wall that just never gets priority treatment, or that messy stack of agave that’s firmly on the “take care of that someday list”. Well, now’s the time! These may be opportunities for rattlesnakes to find the thermal protection they need to den for the winter.

Over the years, we have removed hundreds of rattlesnakes from overgrown lantana, rosemary, and others. Any plants that tend to drop a lot of leaf-litter are suspect. That deep layer of organic material retains moisture and provides thermal protection.

Time for a yearly deep-maintenance landscaping check in. The rule of thumb: if you can see the ground under a ground-laying bush from above, it’s properly maintained.

2. Make any repairs to, and clean up, the pool equipment areas.

As we’ve mentioned many times, pool equipment is a favorite rattlesnake den for the winter. Concrete pads with rodents, combined with relatively high ambient moisture and a little vibration every time they turn on and off, means the formation of caves. These caves, even though they don’t look like much, can go deep, and be the perfect home for rattlesnakes and other animals.

This situation is what we encounter all winter – these often-neglected spots are perfect for rattlesnakes to camp out over winter.

The back corner of the property, complete with the little wall that usually hides it, is made to forget. For that reason, it often doubles as a graveyard for deflated pool toys, pavers, and old buckets.

Spend a little time this Saturday filling in any holes you find with gravel, repairing any concrete you need to, and cleaning it out. If there are no tunnels, the area is useless for rattlesnakes.

3. Bulk pickup day!

If you’re like most of us, you have a stack of roofing tiles or pavers someone on the property. We stack them there to deal with later, maybe have them around just in case a tile breaks or … whatever. But let’s be honest with ourselves; it’s been years and we haven’t touched them.

Time to go! Especially if stored near a wall or against the foundation of the home, as they tend to be, rodents will use them. These situations where rodents create tunnels under a stack of bricks are absolutely perfect for rattlesnakes to use during the winter. Fortunately, it’s as easy to take care of as posting “free pavers! come and get em” on Facebook Marketplace.

Any other debris, too, has to go. You’d be surprised to learn how many winter rattlesnakes we pull out of situations like debris from the previous-summers kitchen remodel, old pool toys and unused stuff of all kinds. If you need a little motivation to finally kick this stuff to the curb, here it is: RATTLESNAKES WILL LIVE IN YOUR YARD IF IT’S THERE. Feel free to use that with your spouse this Saturday. You’re welcome.

4. Get snake fencing installed already.

If you live in Arizona, snake fence installations are probably something you’re familiar with. It’s a physical barrier that is designed and installed in such a way that it keeps them out of an area. If done properly by a reputable company *cough cough*, you could make rattlesnake heaven in the backyard and they’d not be able to come in.

Unlike the other items on this list, this one isn’t free. However, it is the most effective way to go, and removes the subjectivity. While everything else will have a high likelihood to decrease the chances of seeing a rattlesnake, snake fencing all-out prevents it.

If getting a snake fence installed has been on your list for awhile, right now is the best time to do it. It’s also near the end of the season, so discounts may be available. Here’s a massive and detailed guide of what to look for in a snake fence provider to help you in your snake-free journey.

You can barely see it, but this viewfence has snake fencing installed.

5. Seal up and clean out the garage.

If someone told you about a spacious, comfortable house … kept nice and warm (or cool), secure and safe, with free food … oh, and free … would you move in? Rattlesnakes say “YES”! The house we’re talking about is your garage. Every winter and early Spring, we get many calls for rattlesnakes who’ve found a comfy garage to spend the cool months.

That stack of boxes along the back wall? That’s cover. To you the garage may be highschool yearbook and christmas tree storage, to snakes it’s a furnished condo. If possible, find another spot for storage. Especially along the walls, rattlesnakes will take advantage of easy hiding spots.

If you are storing in your garage, use plastic boxes with lids so that rodents and snakes can’t use them, too. You can also get storage shelves (easy to buy and install from Amazon and other places) so that they’re up off the ground at least 5 or 6 inches. These actions help reduce the thermal protection that is attractive to snakes.

This Western Diamondback Rattlesnake found a nice place to hide in the corner of this garage. The leaf litter in the corner is an indication that the seal should be replaced.

You should also seal it up! It doesn’t take long for hot weather and rodents to make short work of the rubber seal on the garage door. If your garage door doesn’t close to allow no greater than 1/4″ at any point, you should consider calling a garage door company out to get it replaced. They may have a seal option that is made to keep bugs out, which would work just fine for rattlesnakes as well.

6. Fix any cracks or openings in the foundation

Not only for homes, but external garages and sheds, too. If there’s access under the home, animals will find it and use it. Rattlesnakes certainly do, too. If you notice that there’s a way in or under the foundation of your home, don’t wait to get it fixed.

Walk the property perimeter (this only takes a few minutes) and identify any potential issues. If you want to fix them quickly, you can get something from Home Depot to quickly seal it up. Or, have a concrete repair company make the repairs … you’ll want to get on that quickly, though.

Any opening into the wall or foundation may be used by a rattlesnake. Fortunately, it’s often an easy fix.

7. Attend to the wood pile!

It’s almost firewood season! Unfortunately, rattlesnakes are excited, too. The pile of debris at the side of your house that you haven’t touched since last year is a dream scenario for rodents and snakes alike. It’s basically a free log cabin.

Firewood maintenance can help avoid this sitation.

Fortunately, there are a couple of easy fixes here:

Use a stand or lift to keep the firewood up off the ground at least 6 inches. This will eliminate much of the thermal protection and make it useless to snakes.
Move the location of the woodpile each year. Even if it’s to the spot immediately next to it, it will help. When a woodpile has been in the same location for years, it invites rodents, often has tunnels under it, rotting material, and all the good stuff that they like.

8. Go deep! Go through the full checklist

The steps you take to keep rattlesnakes away from the yard are really not different than you’d do in other times of year, though the priority may shift to those potential den situations. If you want to do more, that’s always better. Review the Ultimate Guide to Keep Rattlesnakes Away and follow all instructions that apply.

What to expect.

If you take care of these items, and have an overall perspective of keeping habitat opportunities to a minimum, you will likely never see a rattlesnake in the winter. The spots that they choose are very specific, allowing them to survive and wait for Spring. If none of these spots are offered, your yard is simply not useful.

Usually, based on call volume to our snake relocation hotline and surveys, rattlesnakes are more or less where they intend to be for the Winter by the second week of November. That means that October will be busy. You can expect the most activity to occur in the late afternoon until about 1 hour after sunset. It’s important to keep your garage doors closed during this time, even as weather finally becomes more reasonable.

Rattlesnake in a house! How does this even happen?

Posted on September 1, 2020September 1, 2020 by Bryan Hughes

A rattlesnake in the backyard is one thing … but how about in the house, in the bedroom, and even under the bed? It happens, though, thankfully very rarely.

The thing is: rattlesnakes don’t want to be in your home. There are species of snakes that get in often, daily even, like Nightsakes and baby Longnosed snakes. Rattlesnakes, on the otherhand, for one reason or another just don’t make an effort to come inside. If I were to assume, based on how rattlesnakes handle stress and modify their behavior accordingly, the activity inside a home makes them less than ideal hiding spots.

This rattlesnake was found inside a home; a rare event.

How often does a rattlesnake get inside?

Fortunately, Rattlesnake Solutions has a very large collection of human-conflict data of this sort from over ten thousand individual encounters. It happens, but not very often.

Of all encounters we’ve documented, fewer than 100 were rattlesnakes inside the home. If you remove homes that were previously abandoned, missing entire walls, or in a condition where they should be condemned … you end up with fewer than 40. That puts the chances of a rattlesnake encounter in your home, based on snake removal records, at 0.4%. That puts it into a solid “don’t worry about it and go on with your day” category.

Most of the time, a call to catch a rattlesnake inside a home ends up with a Desert Nightsnake in our bucket. These little guys look quite a bit like a rattlesnake and are often mistaken for them.

How does a rattlesnake get into the house?

Fortunately, rattlesnakes are easy to keep out of the house. They come in the same way we do – right through the front door. Most of the time, a rattlesnake inside a house, and in fact a good portion of the other types of snakes as well, come in through a door left open.

Who leaves the door open in Arizona? Everyone, it seems, on the right cool day. Especially our midwestern friends, where it seems an open backdoor on a breezy spring day is a normal thing, tend to leave that sliding door open a bit during prime rattlesnake activity time.

They also can get in through any other opening. Famously, the wife of a former Maricopa County Sheriff was bitten by a rattlesnake in her office. The reason? Workers had opened gaps into the home, which allowed the snake easy access.

On other relocation calls where we’ve captured rattlesnakes inside the home, the situation is often similar. A home with a wall partially removed during construction, a partially-completed vent removal allowing access, large gaps under garage doors or patio doors, etc. Simply, if there is access to inside the home, animals may find their way in.

What’s going on with this photo of the rattlesnake under a bed?

This photo was from an apartment complex in the North Phoenix, Cave Creek area. Mitch ran out to capture it. Upon arriving, he assumed it would be another nightsnake (which it often is) and had to run back out to the car to get his tongs and bucket after seeing this.

He was able to quickly and safely capture it. But how and why was it in there? And does the resident need to worry about more of them?

As we described earlier, it turns out that the resident left the home for less than 5 minutes, leaving the door slightly ajar. That’s all the time it takes for a wandering rattlesnake to find the cool, air conditioned “cave”, and slip inside.

This also does not mean there are others. Rattlesnakes, while being quite social in a variety of situations, are most often found at homes alone. They do not, as a popular myth goes, travel in pairs.

This also does not indicate that there are more rattlesnake encounters in the Cave Creek area … that is just true, regardless of this particular encounter.

How to keep rattlesnakes out of the house?

The best way to keep rattlesnakes out of your home is to keep doors closed and eliminate access, down to a 1/4″ space.

Sometimes that can be tricky, however. Something we have seen with homes in the valley is an issue with how cabinets are put together. This seems to be the reason behind a majority of nightsnake visits, and at least a few rattlesnakes.

If you look under the sink in your kitchen or bathroom, you’ll most likely see the pipes disappearing into the wall in an orderly, well-sealed way. Behind the cabinets, though, is a different story. The pipes coming into the home may be unsealed. That means if there are any gaps under the cabinet overhang (there most often are), there’s a direct highway from under the home to your bedroom bathroom. This may also be the cause for your scorpion and rodent issues.

The easy fix? Seal the gaps under the cabinet overhang. You could go through the trouble to pull out the whole cabinet, but without knowing for sure there’s a problem to begin with, that’s probably overkill. A Saturday afternoon with some expanding foam is all you likely need.

This small Western Diamondback Rattlesnake was in a kitchen under the cabinets

The other thing you should do is to take steps to reduce the overall number of rattlesnakes visiting your property. That is best done by a combination of property modification (landscaping, etc., here’s our step-by-step guide) and physical barriers, like properly sealed garage doors and rattlesnake fence installation.

So rest easy. While a rattlesnake inside the home is something that does happen from time to time, it’s nothing to be overly concerned with. No need to call the realtor or burn the house down; just keep the door closed and you’ll be just fine.

Past due: Baby rattlesnakes are finally joining us

Posted on August 18, 2020August 18, 2020 by Bryan Hughes

Better late than never – rattlesnakes are giving birth, even without the rain. One of the services we offer are serial property inspections, to continuously monitor properties to evaluate possible rattlesnake activity and provide recommendations to landscapers, pest control, and property managers.

We have been inspecting this particular property for many years, and this is the most interesting thing found there to date.

On the previous inspection, Greyson noted a shed skin in an area at the edge of the property. Knowing a fresh shed during this hot and dry period could indicate an estivation den nearby, he focused on that spot during his visit yesterday, and, whoa.

This mother rattlesnake gave birth to babies after being captured at a home in Phoenix.

Here is what was found: a late-season estivation den with a mixed bag of Western Diamondback Rattlesnakes, with one having given birth in the recent past, and another in a deep blue phase (preparing to shed skin)

While this is not entirely unusual, what is different about this year is that we are seeing that rattlesnakes are having their babies later than usual, and they are doing so in their estivation dens instead of moving to their usually-preferred birthing spots.

This is likely a response to our exceptionally hot (the hottest on record) summer and near-complete lack of rain. This is similar to a recent visit to a home by Dave in Tucson (I’ll be posting this shortly as well) where he captured a total of 14 rattlesnakes.

Are rattlesnakes giving birth later this year than normal?

According to our observations and activity on the relocation hotline: yes, it appears that rattlesnakes are having babies later this year than usual. In a normal year, we start to receive our first calls to capture groups of mother Western Diamondback Rattlesnakes with their newborn babies in early July, usually hitting its peak around the first week of August, then trickling in here or there until around the first week of September. This year, it took much longer for this to be normal, only now (mid-August) has it become routine.

Rattlesnakes give live birth and hang out with the babies for a period of time afterward.

Likewise, rattlesnakes seen in informal surveys and in our study of rattlesnakes in the Phoenix Mountain Preserve have shown that Western Diamondback Rattlesnake and Tiger Rattlesnakes that would have likely given birth by now are still languishing in a gravid (pregnant) state at estivation dens.

While this is in no way a full representation of what’s happening out there, but does represent 10 years of data collection and informal survey observations. It should also be noted that while this is the case in the Phoenix and Tucson areas, it is unlikely to represent behavior in other regions.

Why are baby rattlesnakes being born later this year than usual?

The most notable difference of this year from previous years is the combination of extreme, prolonged heat and a nearly-complete lack of meaningful rain. It has been documented that the birth time of Western Diamondback Rattlesnakes coincide with the onset of the monsoon rain (G. Schuett et all 2013).

This year makes that a little bit tougher than normal. If monsoon rain triggers pregnant rattlesnakes to give birth, what happens when there is no rain at all?

They have to give birth eventually … so what we are seeing is this: The mother rattlesnakes are staying at estivation sites (spots selected to hide away during the hottest summer months) far longer than they normally would. Rather than moving to a birthing site as they normally would, they are having their babies right in place.

This likely isn’t good for the babies, ultimately and unfortunately. They lose moisture more than twice as quickly as adults (J. Agugliaro, H. Reinert 2005). Unless we get some rain soon, that could be big trouble for this year’s babies. We’re hoping for the best, but looking at the forecast … hoping is all there is to do.

How homeowners can keep baby rattlesnakes out of the yard

Keeping the smallest rattlesnakes out of your area is a bit different than the larger ones.

First, the space they need to get in is much smaller … anything more than about a third of an inch can allow access. Second, they make frequent movements and may not necessarily know where they’re going. Unlike adults, who’ve had a lifetime to map out a homerange, babies may show up any place, any time. For that reason, physical barriers are the best bet. Rather than go too far into detail here, I’ll refer you to our guide to keep baby rattlesnakes out of the yard.

The world is changing, and whether a temporary event or longer-term, we have made some changes to our processes so that we can continue working with homeowners in Arizona to peacefully resolve rattlesnake conflicts.

Fortunately, the nature of our works makes this relatively easy for us with just a few changes. We don’t have a central office and already have used technology to organize and cooperate remotely for almost 10 years. We’re a bunch of snake nerds, so “social distancing” kind of comes naturally for us 🙂

Here’s what we’re doing. A lot of it sounds scary but we want you to know that we are taking this situation as seriously as you are:

Update 05/24/21:
Masks are no longer necessary in most situations, based on CDC guidance. For more information about this update, please read this.

Update 05/17/20:
In accordance with recommendations from State of Arizona, we are changing our COVID-19 response policies to include these revisions:

We will resume cash/check/credit card payments upon request.
We will resume snakes found within buildings and homes, and masks will be worn in these instances.

Company-wide:

All Rattlesnake Solutions employees and contractors are required to follow CDC-recommended social distancing procedures at work and at home.
Though Arizona has not issued any “shelter in place” action at this point, where only businesses determined to be “essential” to the health and well-being of the community, are allowed to operate. Categorically, Rattlesnake Solutions would be listed under “exterminators” and “construction” by the guidelines available for states who have issued this order, and federal recommendations. We will watch this closely and continue to provide rattlesnake-related services as needed for as long as we are able to.
Any employee or contractor who feels ill or has come in contact with a potential COVID-19-infected person will be removed from rotation to follow a 14-day quarantine.
In the event that one of our team is tested positive for COVID-19, any customers who have been serviced by that individual will be notified immediately.
