I'm new to bat house construction and have designed and am currently building three houses. They are 20"tall x 16" wide, four chamber, wood houses constructed of 1/2" exterior plywood. I have used recommended design and construction techniques found at BCM, BCI and other internet sources. I will be using 1/8" plastic mesh, http://www.industrialnetting.com/hobby.html applied with stainless steel staples for grip surfaces.
I have a question concerning the use of the plastic mesh. Should I apply it to all interior surfaces or just one side of each space?
Thanks for any help
