Bests & Worsts Reviews from Amazon

One way to encourage bats to move to your bat box is to take damp soil and fill the bottom of the box. After a few days, empty out the soil and hang the box. This works even better if you use real bat droppings from a nearby bat colony, if you can get them. This process gets rid of the scent of humans that could otherwise be preventing the bats from colonizing your bat house.
