The eaves of a building are the part of the roof that overhangs the face of the wall. The fascia is the vertical board attached to the roof rafters and the soffit is the underside part of the eave. This is a prime location for wildlife to enter a building, particularly if the eaves have suffered water damage.
Woodpeckers will drill small foraging holes into the fascia looking for carpenter bees and other insects or drumming holes to attract a mate.
Tree squirrels and raccoons will chew through the eave to gain access to the attic or walls. Smaller holes usually indicate a squirrel has taken up residence, while larger holes provide access for larger animals like raccoons.
Newspaper can be stuffed into a hole to determine if an animal is still using the site. If the paper is not removed after three days, it is safe to start repairs. If the paper is removed, the animal(s) will need to be removed before repairs can begin.

The Wildlife Illinois website was authorized by the Illinois Department of Natural Resources (IDNR) in partial fulfillment of project W-147-T. The website was developed by the National Great Rivers Research and Education Center, 2wav, and the IDNR in partnership with the United States Department of Agriculture Animal and Plant Health Inspection Service Wildlife Services and University of Illinois Extension to provide research-based information about how to coexist with Illinois wildlife.
