Despite their innate deviousness, raccoons can sometimes be pretty sensitive, especially to sound and light. As a result, you can use that to your advantage to ward off the sneaky creatures. You can start by setting up a radio or speaker in your garden and have it play music or a radio talk-show on repeat all night long, which is when raccoons are most active. That’ll make them think that a person is actually in the garden, so they’ll keep their distance. Setting up motion-activated sprinklers or spotlights can also be a good idea, as these can scare the raccoons off and make them think twice before ever coming back.
