Bats are an essential part of a healthy environment. They can be an important part of insect-control strategies aimed at reducing pesticide use, thus reducing pesticide contamination of our watersheds. One little brown bat can catch 1,000 mosquito-size insects in an hour! My smallest house can hold approximately 50 - 75 bats.
Unfortunately, many bat species are declining in numbers at an alraming rate. They are slow to reproduce, most bat species have only one "pup" per year. Bats suffer from habitat loss and human fear based on myths.
I have three (3) bat house models, all of which are certified by Bat Conservation International (BCI) — meaning they have passed all the criteria years of reseach by BCI has determined goes into the success of a bat house.
My houses are made with BCX plywood (which is not chemically treated) and solid pine. All exterior sources are primed with an exterior grade water-based primer, then two coats of exterior grade water-based stain. Interior surfaces have two coats of exterior grade water-based stain and a plastic “toehold” mesh is applied to assist climbing.
Exterior grade screws are used, countersunk, and then covered with wood putty for added weather protection. All joints and seams are caulked during and after construction (bats don't like drafts) with a 35-year durable latex caulk.
Other's bat houses I have seen have 1½ inch chambers. This size is more attractive to non-target tenants such as wasps, chipmunks, etc. requiring more frequent monitoring. All my models have chambers that are 3/4".
Bat houses should be placed by early April, however it may take a year or two for the bats to find it. Once residency is established, repeat use is the norm. Plus, if bats have their own home they won’t have any need for your attic. With every order, I include instructions for bat house placement, as well as mounting techniques.
