There is really no such thing as “bat repellant”. These little animals are quite durable, and seem to be resistant to any conventional repellants. There is one chemical so-called “bat repellant” on the market, but it is also harmful to kids and pets. It’s a moist crystal you sprinkle on the attic floors. This chemical bat repellant does very little to rid you of these bat tenants, drys up, and then spreads through the air to the human tenants!

If you want a better bat repellant method, consider using noise. Bats are famous for their ultra sonic sensitive ears. So any abrasive, loud sound, played continuously, will eventually drive them out. If you have a boom box, put it in the attic, slide in a heavy-metal album and turn up the volume. The uninvited, disease-ridden critters may be gone before the batteries run out!
