Step 1
Locate the point of entry. With the help of friends or family, set up watch posts starting at sundown and lasting about one hour. This is the time when you can expect to see bats exiting your home to hunt at night.
-
Step 2
Build a bat house. Once you've found their passageway, place one or more bat houses in the area to help ensure permanent relocation. This gives the bats an alternative place to nest.
-
Step 3
Choose the right time of year. Before moving on to the next step, be sure that you're getting the bats out of your house between the months of August and May. This is when the babies can fly and care for themselves; if you try to get them out during the summer, they'll only become trapped in your house.
-
Step 4
Block the hole with wire mesh by securing three sides of the screen with duct tape. Leave a small space at the bottom of the hole to allow the bats to leave at night but unable to get back in when morning comes. With re-entry blocked, they'll seek out a new home in the bat houses.
-
Step 5
Repeat as necessary. You may find that a few stubborn bats are reluctant to relocate. Keep the mesh in place until all the bats are out of your house, and if this doesn't work, consider plugging the hole completely each night until they're gone.
