Common signs are dark droppings that crumble, stains on walls near gaps, a strong ammonia smell and squeaking or scratching at dusk and dawn. Droppings often collect in piles below entry points. A wildlife professional can confirm it.
It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.
The animals come out first. Wildlife professionals handle exclusion, and rules about bats can vary by species, season and place. Cleanup follows once the space is no longer in use by animals.

Buildings with years of buildup can hold thick, dry, dusty guano that is easy to disturb. Crews ventilate, wet down and use respirators and containment to keep spores out of the air.
