Raccoons can survive on the unwitting generosity of humans, according to the Peninsula Humane Society. The nocturnal critters feast on our garbage, find water in our swimming pools and pet water bowls and seek refuge in home crawlspaces, attics and decks. While it is not possible to eradicate raccoons completely, there are steps you can take to remove them from your area naturally. Installing motion-detecting lights around your home, as well as using heavy-lidded trashcans, are some ways to discourage raccoon foraging. You can also make repellent recipes using a few household items.
Boil the cayenne pepper, onion and jalapeno in 2 qt. of water. Remove from heat and let cool.
Strain the mixture through a cheesecloth and pour into a spray bottle.
Apply the spray liberally in areas where you suspect raccoon activity. Reapply every three to five days.
Place a rag in a shallow dish or bowl.
Pour ammonia over the rag until it is soaked; pour enough so that the rag will soak up the ammonia over the course of several hours at night.
Place the dish where raccoons are a problem; make several ammonia stations, but avoid putting them on your lawn because ammonia will burn your grass.
