Why Are There Bats in the Walls?
Bats sometimes enter a home in search of a place to nest. Common indoor roosts include vacant upper floors, wall voids, and attics. These spaces provide the darkness and seclusion that the pests crave.
Finding droppings on siding or roofs is a serious sign that these animals are nesting in the house. Homeowners can also listen for rustling, scratching, or squeaking noises at night to detect bats in walls or attic spaces.
Problems with Bats in Walls
In addition to creating noise, a bat in house walls may become stuck. This is especially common for young bats, which have not yet mastered flying. If left alone, trapped bats often starve and die in wall voids, attracting rodents, cockroaches, and other pests with the smell of decay.
Baby Bats in Wall Voids and Attics
When homeowners seal off access points to exclude a colony of bats in the walls, newborn or baby bats may remain in the roost. These juveniles are flightless and depend on their mothers for roughly the first three months of their lives. For this reason, residents should avoid bat-proofing homes from May to July.
Getting Rid of Bats in Walls
Attempting to seal entrances without removing all bats first can also push the pests into other areas of the home. Bats without an exit route are more likely to find their way into living spaces looking for a way out. Residents who discover bats in house walls or elsewhere should contact the wildlife experts at Critter Control.
