Squirrels are one of the most common causes of attic noise — and one of the most damaging. Fast, light scurrying sounds during the day almost always mean squirrels. They invade attics for warmth, shelter, and to raise their young, and they cause serious damage while they’re at it.
Signs You Have Squirrels in Your Attic
- Fast, light scurrying sounds — especially in the morning and late afternoon
- Chewed wood, wiring, or insulation in the attic
- Small round droppings, similar to raisins in size
- Entry holes around roofline, vents, or eaves — often with gnaw marks around the edges
- Nesting material — leaves, insulation, and other debris gathered in a corner
- Acorns or other food caches stored in the attic
Why Squirrels Are Dangerous in Your Home
Squirrels might seem harmless, but in your attic they pose serious risks:
- Chewed electrical wiring is the leading concern — exposed wires are a direct fire hazard
- Damaged insulation drives up heating and cooling costs
- They breed twice a year (late winter and summer), so one squirrel quickly becomes many
- They gnaw constantly to keep their teeth short — they will chew through almost anything
- Entry holes invite other animals and allow water intrusion
When Are Squirrels Most Active?
Squirrels are diurnal — active during the day. If you hear sounds in the morning and they stop by midday, only to start again in late afternoon, squirrels are almost certainly the cause. They’re most likely to move into attics in fall when seeking warmth, and again in late winter during breeding season.
