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.

Vinegar can keep some animals at bay, like deer, rabbits, foxes, and raccoons. Keep in mind that your household pets, like cats and dogs, also don’t like the smell of vinegar. You can soak rags in white vinegar and put them up around your garden beds to keep the pesky critters from eating your plants.

Identifying the specific animal running on your roof at night can be challenging without direct observation. Common nocturnal roof visitors include raccoons, squirrels, opossums, and rats. Raccoons are bigger and can create heavy thumping sounds. Squirrels are agile and may produce rapid scurrying noises. Opossums tend to move stealthily with less noise. Rats can make scratching or gnawing sounds. To determine the culprit, look for signs like footprints, droppings, or damaged areas near the roof. For accurate identification, consult a pest control professional or set up wildlife cameras near potential entry points.

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.
