Home remedies that work well to repel raccoons include installing a double-wired fence, sprinkling cayenne powder around home perimeters and installing motion detector lights. Sealing garbage cans tightly and feeding pets indoors can also help to keep raccoons away.
Planting thorny plants around homes and gardens works well to deter raccoons, as the sharp thorns are painful to cross. Raccoons are also repelled by blood meal and ash, so sprinkling these substances over high-traffic areas can prevent the animals from proceeding further. Live traps that contain foods such as corn or pet food can work to capture raccoons safely so they can be released back into the wild, but it is important to comply with state trapping regulations.
