Raccoons have the ability to wreak a remarkable amount of damage in a short period of time. Vent ducts, insulation, fan vents, cooling systems, insulation, and even robust wood beams can all be shredded by their razor-sharp claws and teeth. They also defecate and urinate in large quantities, usually in the same place where they have set up their "restroom." This feces and urine become lodged in the insulation and eventually soak through to the underlying wood. All of this means that your raccoon problem is unlikely to improve over time. It's only going to get worse. If a raccoon dies in your home, you'll know immediately since the smell is terrible.
Skunks are nocturnal, which means that they are most active at night. They don't hibernate in the classic sense, but they do go dormant for the coldest months of the year, when many congregate in communal dens for warmth. One of the only other times that skunks tend to mingle is during mating season. Skunks have 4-12 young in litters that are born between late April and early June. They dig holes in lawns, gardens, and golf courses in search of food, however they prefer insects, earthworms, and grubs. They may even burrow under buildings by entering foundation openings if no other means of shelter is available.
