A double sided wall, filled with straw and incorporating very little soil, can become an attractive feature as mosses and lichens colonise. The spaces will be available as roost sites for bats, as well as home for some of the invertebrates upon which they prey. Alternatively, an earth bank faced with dry stone walling may be more suited to your garden. Leave cavities in the centre as well as plenty of small holes in the facing. As artificial tree holes, bat boxes offer an additional option for bats searching for a roost site.
Entrance is usually by way of a narrow slot underneath.
Use of Chemicals Avoid using chemicals. Certain insecticides may not only cancel out much that you are doing to encourage bats, but also harm the bats themselves.
