3 months is a very short time for observation because it may take several years to attract bats. Batcon.org regularly updates their guide to bat houses based on volunteer research (which you can help with). The design, finishing and placement of the bat box will determine the success so read the guide carefully and experiment to see what attracts bats. The color of the house and amount of sun make a big difference. Research shows multiple boxes near each other will greatly increase your success rate. Placing bat boxes in an area that already has bats (especially that are using a building) will help. Consider contacting pest control companies to find a build owner that wants to exclude bats and set up your bat boxes as an alternative. The location is already proven and you will be providing needed homes for the bats. Properly placed bat houses can find success in almost all climates.
