Chirping noises, droppings, scratches on the walls, and stains at entries and exits are all signs that you have bats in your house or, more specifically, your attic. Because bats are nocturnal, there’s a chance that bats have already infested your home before you start to see warning signs, so don’t delay if you notice anything. If you see a bat or two at sunrise or sunset near your property, that’s another telltale sign that they could be setting up shop inside your space.

Certain strong smells may help repel bats, though this is not a foolproof method and is best used in conjunction with other deterrence strategies. Scents like peppermint oil, eucalyptus, cinnamon, cloves, and mint are often suggested as natural remedies. To create a spray, you can mix two cups of warm water with half a cup of sugar and a few drops of your preferred essential oil. Apply this mixture using a spray bottle to possible entry points and throughout the affected area, such as an attic. While this home remedy is popular, evidence supporting its effectiveness is limited.

Yes, bats can cause quite a bit of damage to the attic. Their weight and movement from flying around can damage insulation, and they can chew through wiring and the walls. As if this isn’t enough, they leave their droppings throughout, which carry harmful bacteria and is dangerous for humans to breathe in, not to mention the extremely foul-smelling odor.

Metal coil-shaped retriever tools (around $50) help remove empty nests and debris from chimneys. Unless you are sure the nest is vacant, we recommend calling in a pro to handle bird’s nest removal from chimneys, vents, roofs, and other hard-to-reach places.
