Bat Boxes are not the same as Bird Boxes. There are strict laws covering bat nest sites and boxes as all bats are a protected species. If you know you have bats, or have a garden near water and trees, the erection of bat boxes is an excellent way of helping the species survive. There is masses of information available on the Web on the what, where, when and how plus all the laws. But I have a detailed PDF of my own which is sent with each purchase or can be requested separately.
