Rattlesnake Gives Birth Under a House! Late summer in Arizona means baby rattlesnake season, and things can get interesting fast. In this episode, Marissa responds to a call at a home she’s been to before. A western diamondback is resting along the side of the house, but as she approaches, it quickly disappears into a small hole. When she floods the hole to safely remove the snake, we find out it’s not just one—this is a mother with babies.
