Bat Belligerance

Although we have several different species of bats here in Western Washington, the two most common varieties that infest buildings are the Little Brown Bat, Myotis lucifugus, and the Big Brown Bat, Eptesicus fuscus.

As far as dealing with an infestation of bats, regardless of the species, the Bat Removal procedure is the same.

Although not all bat species are endangered, ALL the bat species are very beneficial for managing insect swarms, and so every effort should be made to avoid harming any bats.  Thus, the focus to solve the problem should be on the building.

Bats do not have calcified bones like we do, and this flexibility enables them to squeeze through extremely small openings.  In order to eliminate a bat infestation, it is important to find all the potential gaps in a structure and seal them.

If you have a metal roof, concrete/slate/or rubber tile roof, or cedar shake roof, you should start by replacing it with an asphalt composition roof.  There is just no way to seal metal, tile, or cedar roofs against bats without adversely affecting the moisture properties of those roofs.  Metal roofs also pose a unique problem in that they expand and contract significantly in the heat and cold which forces new gaps to open in surrounding materials.

If you already have an asphalt roof, then I start by finding all the gaps in your structure.  Your Home is Your Castle, I can make it a fortress. When I have found the bats’ primary access points, I will begin sealing all the OTHER access points, and leaving the primary access points open.  When the bats are restricted to just one to four remaining holes, I will place one-way doors over those access points to make sure the bats can get out, but not get back in again.  They will have to find a new home. Our Bat Removal service creates a permanent solution to your problem.

Timing is also important with bats.  During the late spring and early summer, female bats may leave their flightless young behind in the nursery while they go out foraging.  To make sure that no juvenile bats are trapped inside to die, a nursing colony should not have any one-way doors placed from April to August.  By the time September rolls around, the young are old enough to fly, and so the doors can be placed at that time.   If an exclusion is done in the winter, the one way doors should be left up until May just to make sure that no hibernating bats are trapped inside.

Once I am certain all occupant bats have successfully escaped the fortified structure, we can take down the doors, and then we can seal those access points permanently.

If you are interested in making your structure bat-proof, call!
