What bird & bat guano cleanup covers:
Family members, tenants, staff and pets stay out while the crew plans the work and gets into protective equipment.
Moisture and containment keep spores and particles from becoming airborne during removal.
Guano, matted insulation and nesting debris are packed out, and salvageable items are set aside for cleaning.
Odor and air are checked, and the owner is shown what was done and what remains for other trades.

Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.
