Removing droppings and soiled insulation seems simple, but it is the part of wildlife work with the most health risk.

The risks

Dust from droppings, urine and nesting material can carry bacteria, fungus and parasites. Attics are hot, cramped and full of hidden hazards.

The right method

Professionals use respirators, protective suits and HEPA vacuums, then sanitize the area. They remove soiled insulation in sealed bags.

What to do yourself

You can help by clearing stored items from the attic ahead of time and by keeping people and pets out of the area until it is cleaned.
