Quick Answer
Safely cleaning rodent infestation aftermath involves critical safety precautions. **Never dry sweep or vacuum** droppings, as this aerosolizes hazardous particles like Hantavirus. Always wear a P100 respirator, thick gloves, and eye protection. First, ventilate the area for 30 minutes, then thoroughly spray all contaminated areas with a 1:10 bleach-to-water solution, letting it sit for 5-10 minutes. Gently wipe up materials with paper towels, double-bag them, and dispose of them in outdoor trash. Disinfect surfaces again and deodorize. For large infestations, contaminated insulation, HVAC involvement, or if deer mice are suspected, professional biohazard cleanup is recommended, costing anywhere from $500 for minor cleanups to $2,000-$7,000+ for extensive work.

Possible Causes
Step-by-Step Diagnosis
Step 1
Gear up with proper personal protective equipment (PPE), including a P100 respirator, gloves, and goggles.
Step 2
Visually inspect the property for droppings, nests, and gnaw marks to identify high-traffic areas and the extent of the contamination.
Step 3
Use a UV blacklight in a dark room to identify hidden urine stains on floors, walls, and other surfaces.
Step 4
Determine if the infestation is active by looking for fresh, shiny droppings or using tracking powder to check for new tracks.
Step 5
Thoroughly inspect the home's exterior and interior for entry points and seal them with steel wool and caulk.
