There are lots of different kinds of spiders in the world, and while it may be scary to spot them in your home, most of them are harmless and even helpful at managing pests. Still, we completely understand when homeowners tell us they want spiders to do their bug-eating jobs outside rather than indoors.
Rodent nests are cobbled together with whatever they can find: bits of paper shredding, cloth, cotton, insulation, etc. Rodents like to make their nests in dark and secluded places, such as in walls and attics and under or between floors, where they won’t be bothered. If you happen to find one, there is a strong chance that there are or were rodents living in your home.
If the rodents in your home have built a nest, chances are they’ve also found food. If you start to find greasy or dirty marks along floors or the bottoms of walls, they may be the result of contact with a rodent’s oily fur as it searches for food.
