Quick answer
What to know first
Squirrels enter attics through roofline gaps, vents, soffits, and chewed openings. Prevention should avoid trapping young animals inside and should use chew-resistant materials.
Check first
- Daytime scratching or running sounds in the attic
- Chewed fascia, vents, or roofline openings
- Droppings or nesting material in attic insulation
Avoid this
- Sealing an opening before confirming that animals and young are outside
- Handling wildlife, nests, or droppings without appropriate protection
- Using a method that conflicts with local wildlife rules
