Why are Flying Squirrels Attracted to Wall Voids?

Flying squirrels find their way into homes through cracks in exterior walls, vent shafts, gaps in roof eaves, and improperly sealed windows. The pests can squeeze through holes no more than an inch wide. Their reasons for invading range from seeking shelter in which to rear their young, to escaping cold weather. Once inside, flying squirrels congregate in wall voids, as they provide an environment similar to the pests’ natural habitat.


Damage caused by flying squirrels in the walls generally starts at the building’s exterior. Flying squirrels will chew or claw at exterior holes until they are big enough to grant entry. They are also extremely chatty and make a lot of chirping and scratching noises throughout the day. They let their waste accumulate in wall voids, as well, which starts to smell bad. Furthermore, there have been reports of flying squirrels carrying typhus, as well as fleas, ticks, and lice.

Prevention & Removal

To reduce the possibility of finding flying squirrels in the walls, homeowners should seal off potential entry points. Keeping tree branches trimmed back from the house also helps deter the pests.
