Things You Will Need
Eliminating their shelter and food will naturally cause the bats to come out from hiding and find a new place to live.
-
Control insects around the awning to diminish the primary food source of local bats. Hang fly strips, moth lights, citronella candles or other insect repellents.
-
Hang flood lights or bright bulbs to deter bats away from the porch. Use lighting in combination with insect repellents as the lights may attract insects.
-
Set up a fan under the awning to maintain a constant draft. Bats will not tolerate strong breezes and will move to a draft-free environment.
-
Cover the underside of the porch awning with a mesh screen. Ensure that no bats are under the awning before covering the entrances and exits.
-
Spray a repellent designed for dogs and cats. Chemicals found in pet repellent sprays are also known to keep away bats.
-
Suspend strips of aluminum foil in areas where the bats are nesting. Bats are unlikely to take up residence in areas where light is being reflected towards them.
-
Place moth balls under and around the porch awning. Tie a mesh bag full of moth balls to the awning as the smell is unpleasant to bats.
-
Slap the area beneath the porch awning with a newspaper during the daytime. The noise of the newspaper will most likely drive away the bats.
-
Install a bat house near the awning to drive the bats to their new home. Erect bat houses should stand 10 to 15 feet off the ground and near a water source.
-
Remove bat droppings as bats may be attracted to the odors caused by previous infestations. Clean the affected area with bleach and water solution.
