How to catch a bat in your house: 10 steps (with pictures)
Bat droppings, guano, can grow a fungus that can infect a human. Histoplasmosis occurs when mold spores are inhaled. Symptoms are like pneumonia and may lead to very serious complications, even death. This problem is not likely to occur just because you see a bat in your house. If you have a bat colony in your house, you should have the bats removed and the roosting area sanitized.
Rabies from bats are the leading cause of human rabies. People are sometime bit while sleeping and are not aware of the bite. Bites from bats may not be visible the next morning. If a bat is found in a room with a sleeping person, contact your physician.
A very small percentage of bats may have the disease rabies. An infected bat bumps into walls, furniture, people and objects or is unable to fly. Avoid a bat on the ground. Rabies can be transmitted by biting.
Rabies is 100% fatal if not treated; but 100% preventable. Do not wait until you have symptoms, by then it will be too late!
When trying to get a bat to leave on its own, turn off anything that makes noise. They “see” by sound. Loud noises (such as music) often confuse bats. Turning off anything that makes noise (not just TVs and radios, but clocks and other devices) will go a long way in helping the bat find its own way home.
In the UK there is the Wildlife and Countryside Act 1981 “ which protects bats and their roosts throughout the UK, making it illegal to kill, injure or disturb a bat and this includes blocking up any entrance holes they may be using. If you need help, contact The Bat Conservation Trust.
