Humans have always had some sort of relationship with nature. We keep certain animals as pets, and keep other animals to provide us with certain types of food. We like to live in areas surrounded by nature, as evidenced by the 46 million people living in the Wildland Urban Interface (WUI), which is the transition between unoccupied land and human development, such as dwellings, stores and offices. This interface isn't just vegetation but includes a host of wild animals such as squirrels, raccoons, possums, skunks and other creatures. However, as humans move into these interface areas, the interactions between humans and the creatures becomes complicated.

Humans build nice houses, and many animals take note and decide the human dwelling would be a nice place for them to nest too. Raccoons, squirrels, and bats in the attic, raccoons and skunks under the porch, are just some of the ways wild animals have decided to move into our dwellings and camp out.

Unfortunately, the animals aren't the best tenants; they create their own entrances, tend to make a mess when they build nests, don't use the bathroom, preferring to just relieve themselves wherever when nature calls, and they almost always leave the property in a worse condition than when they found it. Homeowners then have to evict these bad tenants and clean up the messes.
