Bats in the house
Bats are frequent visitors in both old and new houses. They are small, harmless mammals that do not cause any damage within your house.
Finding bats in your house
They do not make much noise or smell and their droppings soon crumble away to dust. They do not use bedding, or return with any insect prey to the house. Indeed, householders are usually unaware of them.
Whatever the age of your house, it is possible that bats will find somewhere to roost within, either in the roof space, under a roof tile or lead flashing, even between gaps in mortar or behind fascias and soffits. A roost is not likely to be used all year round, but bats will return at appropriate times each year to a traditional site.
All bats and their roost sites are fully protected by law, even if bats are not present all the time. If you have bats in your roof, their access must not be impeded.
If any problems are encountered with bats, or if any repair work to the roof is necessary, advice must be sought from the relevant statutory nature conservation agency.
IMPORTANT: if you find a sick or ailing bat, you should not approach or handle the animal but seek advice from the Bat Conservation Trust.
