Aside from the fact that bats serve as roving pest control specialists, bat houses are just plain cool. The Schrodt Colony Bat House features a brass moon and bat design that adds to its fun nocturnal charm. Bats eat beetles, wasps, mosquitoes and moths. So, having them nearby is a good thing. That is, unless, you like beetles, wasps, mosquitos and moths. This recycled redwood bat house model is a triple chambered nursery capable of accommodating dozens of mature bats and their offspring.
