Heavy footsteps especially at night can be a dead give away.  In the spring, noises in the attic along with crying or chattering noises can come from a female that has given birth and is very common.  Our insulation makes a wonderful nursery material.  Other signs include a change in smell in the home and staining. 

One important item to note is that after getting raccoons out of your attic, it is important to also treat for fleas.  Most raccoons have fleas and when they are removed from a home the remaining fleas left in your attic have nothing to feed on and will enter the home in search of a blood meal from a resident or pet.  At Elite Wildlife Services, we take the time to investigate and recommend sanitation and pest services so our customers are not left with a flea problem.
