Bats in your home
Fall is a good time to make repairs to houses and sheds if you want to prevent bats from getting into structures. By now resident bats have gone to their winter quarters. If you know the entry points for bats using a building, cover the hole with a flap of duct tape or roofing paper. If a bat was inside, it could get out but the flap will prevent a bat from re-entering the structure. Remember that a bat only needs a 5 mm (1/4 inch) crack to be able to crawl inside.

One you’ve sealed the holes, erect a bat house so that next year’s bats have a place to roost. Ideally situate the house facing south or exposed to the full sun. The bats like a clear area to fly into so avoid decks, shrubs, or tree foliage in a three meter area around the bat house. If you are using a pole, put up a house on two sides so the bats get a choice of temperatures. Sealing up or destroying a maternal colony can spell disaster to a local bat population so anyone in this situation is asked to contact wildlife authorities to get advice on erecting an alternate structure.
