As a wildlife removal company in the Portland Metro area, we get a lot of calls from people dealing with nuisance wildlife. Most of those calls are from home owners that have not actually seen a raccoon, opossum or other type of animal in or around their home. Most of the calls are from what they hear in their home. Scratching, gnawing and scurrying are usually a sure sign of an animal in your attic or crawl space.
We have a lot of raccoon's living in the Portland Metro area. Some of them live in trees, some live in dens and some of them try very hard to live with you in your home. If they are lucky enough to get access to some of your unused spaces like the attic or crawl space, they will make themselves right at home, get cozy and probably even have a few babies. The damage that they do to an attic or crawl space can be catastrophic. We inspect a lot of homes that have (or have had) raccoon's dwelling underneath them and the damages generally amount to between $1,000 and $4,000 when they are needing a crawl space restoration.
