How to Safely Clean Up After a Rodent Infestation

Rodents leave behind more than just chewed wires and ruined insulation; they leave a trail of dried urine, feces, and nesting materials that carry health risks. Attempting to vacuum or sweep this debris is a common mistake that kicks microscopic, infectious particles into the air where they can be inhaled. Doing this job well means prioritizing containment and personal protection over speed. Success in this project is defined by zero dust generation. You are effectively isolating biological hazards and removing them from your home without allowing them to migrate to your living spaces. Wear the right gear, work slowly, and dispose of everything as if it were hazardous material, because for the next few hours, that is exactly what it is.

1. Clear the Air First. Open every window and door in the attic or crawlspace to create cross-ventilation. Leave the area undisturbed for at least 30 minutes before entering to ensure any airborne particles have settled.
2. Suit Up Completely. Put on a pair of disposable nitrile gloves and an N95 respirator mask. Wear long sleeves and pants that you can either wash in hot water or discard immediately after the job is done.
3. Saturate Everything. Mix a solution of one part bleach to ten parts water in a spray bottle. Thoroughly soak all droppings, nests, and contaminated insulation with the solution and let it sit for five minutes.
4. Bag It All Now. Use paper towels to pick up the soaked waste and place it directly into a heavy-duty plastic trash bag. Carefully peel your gloves off and place them inside the same bag before tying it shut.
5. Wipe All Surfaces. Once the visible waste is removed, mop the floor or wipe down surfaces with the bleach solution. Use clean paper towels to wipe the area dry to ensure no moisture remains.
6. Decontaminate Everything. Spray all tools used with the bleach solution and wipe clean. Place all work clothing directly into the washing machine for a cycle with hot water and heavy-duty detergent.
