Squirrels may seem harmless, but when they invade your home, they can cause serious damage. One of the first warning signs is hearing scratching or scurrying noises in your attic or walls, especially during early morning or evening hours when squirrels are most active. These sounds often resemble quick, light footsteps or rolling noises as squirrels move around and rearrange insulation or other materials. Another indicator is finding chewed entry points, particularly around rooflines, vents, or eaves. Squirrels have strong teeth and can gnaw through wood, plastic, and even soft metals to create or widen openings. If you notice small piles of debris, such as twigs, leaves, or insulation, near potential entry points, it could be a sign of nesting activity. Additionally, keep an eye out for droppings, which are typically cylindrical and about the size of a grain of rice. These droppings can accumulate in attics, garages, or crawl spaces. Lastly, if you see squirrels frequently around your property, especially near potential entry points, it’s worth investigating further. Ignoring these signs can lead to costly repairs, as squirrels can chew through electrical wiring, causing fire hazards, and damage insulation, leading to increased energy bills.
