Bats are mammals. They have hair or fur on their bodies, are warm blooded and are the only mammals that can fly. Mother’s will give birth to a single young which will start flying at three weeks old. Bats living in the UK generally eat a variety of insects. They hibernate in the colder weather to conserve energy when insects are harder to find. Bats don't make nests but choose various places to roost throughout the year with other bats. Some prefer hollow trees or caves, others use both at different times. Many shelter in buildings, behind roofing tiles and boarding or in roof spaces. You may realise you have bats living in your property during the summer time when they are most active. They don't cause damage to cables or timbers and their droppings may concern some people but there is no evidence of any significant disease risk. In addition to this, you may discover bats living at your property whilst carrying out work
