Raccoons are very intelligent animals and have been known to remember places where they have found food in the past. If you have a raccoon that is coming around to your property regularly, chances are it has found a consistent food source and will continue to come back as long as the food is available. In some cases, raccoons can become nuisance animals if they are constantly raiding your garbage cans or getting into your garden. If this is the case, you may want to take steps to deter them from returning.
