How to Place a Bat House Safe From Squirrels
Bats are welcome nighttime predators. They feed on mosquitoes and other insects, helping to keep these populations in check. Hanging a bat house near your home encourages bats to nest nearby, where their feeding habits will benefit you most. While you may never see your nocturnal tenants, the decreased amount of biting insects in your yard will be a welcome gift. Squirrels will take over bat houses and drive away the occupants if you don't take measures to stop them, so you must be sure to squirrel-proof your house. Does this Spark an idea?

1
Purchase a bat house with an open bottom. Bats do not require a floor in their nest but squirrels do. Choosing an open-bottomed house prevents most squirrel problems.

2
Hang the bat house on a pole or tree 15 to 20 feet above the ground. Choose an area that receives at least six hours of direct morning sun and some afternoon shade.

Place a baffle on the pole both below the house and above it. Cone-shaped baffles form a barrier on the pole and prevent squirrels from climbing over it to the bat house. Make your own by cutting a piece of aluminum sheeting to fit around your post. Wrap it around until the ends meet, adjusting it to form a cone. Position the cones on either side of the house so the wide end of the cone is closest to the house and the narrow end is furthest away. Nail in place.

Check the bat house in late winter before the bats return for any unwanted pests such as squirrels or wasps. Remove any nesting material from the house and dispose of it to drive the pests away.

Tips & Warnings
Hang the bat house on a post or wall when available, as squirrels are less likely to find them there than on trees.
Keep bird feeders away from bat house locations, otherwise birds may also begin trying to nest in your bat house.
