How to Use a Plastic Owl to Keep Bats Out

Bats are beneficial mammals that eat 30 to 100 percent of their body weight in insects each night. However, you may want to avoid having them near your home. Keeping bats out of your home is as simple as placing one of their natural enemies, the owl, near their roosting place.

Step 1

Purchase a plastic owl that has a lifelike all-weather surface.

Step 2

Mount the plastic owl as high up as possible, ideally above where the bats are roosting or could enter your home, and against the skyline for maximum effect. Use mounting screws to secure the plastic owl to the tree, trim or roof .

Step 3

Move the plastic owl at least three times a year to keep the bats aware and fearful of it.
