What are some good bat repellents?

Some effective bat repellents include mothballs, Mylar strips and commercial pet repellent products. Placing these items near the bats' roosting area can encourage them to relocate. Spraying the bats with water is another option that causes no harm to the animals.

No method is guaranteed to repel bats during their maternity period, since adult bats refuse to leave nursing babies. In the United States, the season lasts from approximately the beginning of May until the end of August.

When attempting to deal with a bat infestation, never touch the bats with your bare hands. The animals carry diseases, including rabies, that can harm humans.
