Signs include visible nests, droppings, frequent loud noises, or structural damage caused by these animals, indicating a need for pest control intervention.

Look for goose repellents that contain the ingredient methyl anthranilate. This is a natural chemical found in grape juice. In human food, it’s often used as grape flavoring. With geese, it’s highly irritating. Grape Kool-Aid contains methyl anthranilate, the active ingredient in most bird repellents. It won’t harm geese, but it will deter them.

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.

Fake owls are a common goose deterrent decoy and one of the most humane ways to scare away geese. Unfortunately, some geese are wise to fake predators. Decoys can be more effective if you move them around frequently or purchase ones with motion features. Decoys that move in the wind are also more effective than stationary decoys.
