Raccoons can be one of the trickiest pests to remove. Yet they are also common all over North America, meaning that they consistently cause problems in homes in California as well as in every other state. They are fairly intelligent, know how to climb, can recognize traps, and they often want to nest in someone’s attic to have babies. Gardens, rooftops and underground plumbing are also areas that can be devastated by raccoons once the animals decide to visit regularly or reproduce nearby.
