To make raccoon repellent, boil five chopped habanero chiles and 1 cup of cayenne pepper in a pot of water. Strain the mixture into a spray bottle, and spray the mixture in the affected areas. Repeat the application every three to five days until the raccoon activity ceases. For best results, clean garbage cans with vinegar and water to avoid attracting the pests, and remove other food and water sources in the area.
Another option is to combine a bottle of hot sauce, or a container of cayenne pepper, with 1 teaspoon of liquid dish detergent and 1 gallon of water. Pour the mixture into a spray bottle, and spray the affected areas frequently until the raccoon activity stops. Use pepper-based sprays with caution, as the spray causes irritation to the eyes, nose and mouth.
Scent-based deterrents are also an option. To use scent-based deterrents, soak a cloth in apple cider vinegar or ammonia, and place the cloth in the affected areas. If the raccoons remove or bury the cloth, replace it with a newly soaked cloth.
To increase the effectiveness of the chosen deterrent, remove debris from the property, and keep the lawn and garden well-maintained. Avoid using mothballs to deter raccoons, as mothballs are toxic to humans and animals.
