Timing is the most reliable initial indicator. Sounds during the day — especially morning and afternoon — suggest squirrels. Heavy thumping and movement at night is typically raccoons. Quiet, occasional rustling in warm weather is often bats. Chattering from a fixed location can be birds in a vent. A professional inspection will confirm the species and provide the information needed to address the situation correctly.

It depends on the species and situation. Going into an attic where raccoons are nesting — especially a mother with young — is not advisable without experience. Bats should not be handled without appropriate precautions. Squirrels will typically scatter from a person entering the attic, but may have created conditions (contaminated insulation, damaged wiring) that require careful handling. For most situations, letting a professional do the initial inspection and removal is the safest approach.

Coverage varies by policy. Some homeowners insurance policies cover damage from certain wildlife — particularly if it can be characterized as sudden and accidental damage. Wildlife contamination and gradual damage are less consistently covered. Contact your insurance provider to understand your specific policy. Document the damage thoroughly regardless of coverage status.

Not always immediately, and not in every case. If contamination is limited and confined to a small area, targeted removal of the affected insulation may be sufficient. Extensive contamination — particularly from a large raccoon colony or long-established bat roost — typically warrants a more complete attic remediation. We assess this as part of the inspection and provide honest guidance on what is actually necessary versus what might be upsold unnecessarily.
