Signs of Squirrels in or around Chimneys When selecting places to construct nests, squirrels typically look for secluded areas off the ground with plenty of cover. While squirrels rarely infest chimneys themselves, the pests may nest in metal chimney boxes (see picture below). If a squirrel falls down a chimney and becomes trapped inside the fireplace, homeowners may be alerted to their presence via various sounds, smells, sights. Residents may hear chittering, fighting, or scratching at all hours of the day, smell squirrel droppings, and even see the pests running loose inside the home. Damage Squirrels destruct roofing and siding as they attempt to gain access to chimneys or attics. They bend vents, rip up insulation, and gnaw on electrical wiring inside homes, which creates fire hazards. The pests also chew holes in siding, fascia, and gables while searching for suitable dens. Collections of droppings and urine generate awful smells that permeate houses. Additionally, accumulations of waste contribute to the spread of salmonella and Leptospirosis. Removal Trapping is not legal in many states, and squirrels frequently return to their nests if they're not relocated far enough away. To avoid legal retribution and repeat infestations, homeowners should contact experienced wildlife control experts to handle squirrels in or around chimneys. Professionals not only eradicate existing infestations but provide tips on preventing the pests from returning.
