Squirrels in Homes: Ceiling Noise, Wiring Risks

Scratching in the ceiling at dawn or dusk is often squirrels.

The short answer

Squirrels enter roofs, false ceilings and chimneys, nest, chew wires and insulation, which can cause electrical faults and fire risk. Seal entry points, trim branches that touch the building, use mesh covers on vents, and use humane measures. A professional can inspect, remove squirrels humanely and proof entry points. Have an electrician check chewed wiring.
