I keep hearing about is snakes in the attic but not about snakes in my insulation. I saw a snake in insulation for the first time when I went to a clients home in Dayton, Ohio, when the clients were complaining about noises in their walls and thought they has a mouse or rat problem. The snake in the video below was retrieved from insulation in this client’s home. The snake in the video is called a Black Rat Snake which is nonvenomous. This species is a constrictor, meaning it suffocates its prey, coiling around small animals and tightening its grip until they can no longer draw breath, before eating them. Though they will often consume mice, voles, and rats, black rat snakes are far from specialists at this kind of prey and will readily consume any small vertebrate they can catch. Other prey opportunistically eaten by this species can include other snakes (including both those of their own and other species), frogs, lizards, chipmunks, squirrels, juvenile rabbits, juvenile opossums, songbirds, and bird eggs.
Also, if you do in fact have a snake in your home, basement, attic, or even in your insulation most probably you have mice and rats in those places as well. If a rat or mouse can fit into an opening and get into some habitat, a snake can smell that rat or mouse, and it will slither through the same hole, in an attempt to find and eat the mouse and or rat.
