After animals are removed, the damage remains. Bat guano, raccoon feces, rodent droppings, urine-soaked insulation, parasites, and fungal spores do not disappear on their own. TriState Wildlife performs full attic decontamination and restoration for homes across New York, New Jersey, and Connecticut. We remove contaminated insulation, HEPA-vac the space, apply antimicrobial treatment, and re-insulate. Insurance claim assistance included. In many cases, your homeowners insurance covers the full cost.
How We Work
Our Decontamination Process
Step 1: Containment. We seal off the attic from the rest of the house using plastic sheeting and negative air pressure to prevent cross-contamination. Spores, dust, and particles stay in the work zone.
Step 2: Removal. Trained technicians wearing hazmat-grade protective equipment bag and remove every piece of contaminated insulation. Material is double-bagged and disposed of at a licensed facility.
Step 3: HEPA Vacuuming. The entire attic space is vacuumed with commercial HEPA-vac equipment that captures particles down to 0.3 microns. This removes residual droppings, dust, and spore-laden material.
Step 4: Antimicrobial Treatment. We apply a professional-grade antimicrobial agent to all surfaces. This kills bacteria, fungal spores, and neutralizes odor at the molecular level.
Step 5: Re-insulation. Once the space is certified clean, we install fresh insulation to the appropriate R-value for your climate zone. Your attic is restored to pre-damage condition or better.

When Is This Needed
Common Decontamination Scenarios
Bat colonies. Bat guano accumulates over months or years. The fungus Histoplasma capsulatum grows in guano and causes histoplasmosis when spores are inhaled. This is the most common scenario requiring full decontamination.
Raccoon latrines. Raccoon feces contain Baylisascaris procyonis (raccoon roundworm), which causes severe neurological damage in humans. Professional decontamination is required, not optional.
Rodent infestations. Mice and rats contaminate insulation with urine and droppings. Hantavirus and other pathogens are transmitted through airborne particles from disturbed droppings.
Squirrel damage. Squirrels compress and contaminate insulation, reducing R-value. They also chew wiring, creating fire hazards that must be addressed before re-insulation.
Insurance
Insurance Claim Assistance
Attic decontamination and restoration from bat and raccoon damage is often covered by homeowners insurance. Bats and raccoons are mammals, not pests, and the damage they cause is typically covered under the same provisions as other animal damage.
We document the damage with detailed reports and photos, prepare the claim documentation, and work directly with your insurance adjuster. In many cases, our clients pay nothing out of pocket for the decontamination.

"Bat guano everywhere. Three inches deep in some areas. TriState removed all the insulation, HEPA-vacuumed the entire attic, and re-insulated. Insurance covered the whole thing. Our attic looks brand new."

Common Questions
Attic Decontamination FAQ
In many cases, yes. Bat and raccoon damage is often covered by homeowners insurance because bats and raccoons are mammals, not pests. We document the damage, prepare the claim, and work directly with your adjuster. Many of our clients pay nothing out of pocket.
Pricing depends on the size of the attic, extent of contamination, and amount of insulation to be replaced. We provide a detailed written estimate after inspection. With insurance, your out-of-pocket cost may be zero.
Yes. Bat guano can harbor the fungus Histoplasma capsulatum, which causes histoplasmosis when spores are inhaled. Symptoms include fever, chest pain, and cough. Do not disturb bat guano without proper protective equipment. Professional decontamination is recommended.
We strongly advise against it. Bat guano, raccoon feces, and rodent droppings contain pathogens that become airborne when disturbed. Professional equipment (HEPA-vacs, hazmat suits, respirators) and containment procedures are needed to prevent exposure and cross-contamination.
Most residential attic restorations are completed in 1 to 3 days depending on the size of the attic and extent of contamination. Larger projects may take longer. We schedule efficiently to minimize disruption.
