This will be a big one … as the season winds to a close, snakes are busy. Not only are they looking for a last meal or two and mating, they have to travel to the places they plan on spending the winter. These dens, in the low and warm desert, can be just about anywhere that a snake can escape freezing temperatures and preserve the moisture they’ve been able to get during the year.
Typically, we remain quite busy through October and into about the second week of November. After that, rattlesnake activity decreases dramatically.
When do snakes go to sleep for the winter in Arizona?
Typically, primary rattlesnake activity ends in mid-November in the Sonoran Desert, and a few weeks earlier in higher elevations.
