Yes. All bats and their roosts are protected by law (even if a bat is not in the roost at the time). It is illegal to deliberately capture, injure or kill a bat, disturb a bat(s) in its roost; damage or destroy a bat roost, possess/advertise/sell/exchange a bat (or parts of a bat) whether dead or alive, or obstruct access to a bat roost.
If you regularly see bats in your garden, it’s possible that they are roosting in your home, or perhaps in one of your neighbours’ houses. Call the Bat Helpline (0845 1300 228) to ask for a copy of the ‘Living with bats’ booklet, which gives advice on what to do if you share your house with bats. Norwich Bat Group would also like to hear about the roost, visit their website at www.norwichbatgroup.org.uk
