Yes bat houses do work. Alot of research has been done on bat houses to get an idea of what they like, and it seems that the temp inside the house has alot do with the occupation. It may take the bats a while to find the house and of course only bats the colonize are going to use them. Big brown bats (Eptesicus fuscus) are notorius for using houses.
It is recommended to place the houses from 15 top 20 feet off the ground and preferably around a water site (pond, lake, ditch) that holds water and draws insects for feeding. Again placement is important in relation to sunlight due to the box needs to reach a certain temp and not exceed another. They do work well on the sides of buildings, barns, pine trees and other structures. Some people have researched painting the houses different colors and the research is still out on if this makes a difference in drawing bats.
A good source for this info is at Bat Conservation Internationals website. They even have a bat house builders book that you can purchase that gives examples of different types of houses to build and what types of bats to expect. Hope this helps.[/i]
