Pest & Vermin Droppings Cleanup in Chicagoland 

Guaranteed Attic Decontamination

Rats, mice, squirrels, raccoons, and bats don’t just chew wires and ruin insulation — their urine and droppings carry dangerous pathogens like hantavirus, salmonella, and histoplasmosis. One attic full of contaminated insulation can make your entire home unhealthy.

At The Attic Genius we’ve removed countless pest infestations and restored attics to clean, breathable condition for over 25 years. 400+ combined five-star reviews across our companies prove we’re the team homeowners trust when animals have taken over their attic.

Why Pest Droppings Are a Bigger Problem Than Most People Realize

Animal waste isn’t ordinary dirt. It’s biohazardous:

- Urine soaks into insulation and wood, creating permanent odor and health risks 

- Droppings harbor viruses, bacteria, and parasitic roundworms, and fungal spores 

- Contaminated insulation loses almost all R-value and becomes a magnet for mold 

- Fleas, mites, and ticks often stay behind even after the animals are gone 

Simply setting traps or sealing entry points is only half the job. The mess they left behind must be completely removed and the attic sanitized — otherwise you’re still living with the danger.

Our Complete 7-Step Pest Cleanup & Attic Restoration Process

1. Free Attic Pest & Damage Inspection 

   We identify the animal, locate all entry points, assess droppings volume, and check for chewed wiring or structural damage.

2. Full Home Protection & Containment 

   HEPA-filtered negative air, sealed work zones, and crew in full PPE so nothing spreads.

3. Safe Removal of Contaminated Insulation 

   Every bit of soiled, urine-soaked, or nesting-laden insulation is vacuumed into sealed bags and removed the same day.

4. Droppings & Debris Removal 

   HEPA vacuuming of every rafter, joist, and corner — no sweeping, no dust clouds.

5. Sanitization & Disinfection 

   Hospital-grade, EPA-registered antimicrobial fogging and wipe-down of all surfaces.

6. Odor Neutralization 

   Enzymatic treatments and thermal fogging eliminate urine smells permanently.

7. Prevention & New Insulation 

   We seal obvious entry points (partner with trusted exterminators for full exclusion if needed) and install fresh, clean blown-in cellulose or fiberglass insulation to current code.

All work backed by our written 10-year warranty.
