If you’ve had pests in your attic or crawl space, the mess they leave behind in your insulation can continue to pose health risks, cause odors, and ruin your home’s energy efficiency. At Airlock Insulation, we specialize in safely removing contaminated insulation and installing pest-resistant materials to restore a clean, healthy, and energy-smart home environment.
Why Pest Infestation and Insulation Go Hand-in-Hand
Rodents, squirrels, raccoons, and even birds love insulation. It’s warm, quiet, and undisturbed—making it the perfect nesting material. But when pests move in, they do more than just set up shop:
- Urine and droppings contaminate the insulation, leaving behind odors and airborne particles.
- Tunnels and nests create gaps, which drastically reduce the insulation’s R-value.
- Chewing damage to insulation, wiring, and even wood framing.
At Airlock, we’ve worked in hundreds of homes across Northeast Ohio where insulation was no longer safe or effective after a pest invasion.
“We had a home in Geauga County where raccoons got in through a ridge vent. The attic smelled awful. We vacuumed out the insulation, sanitized the cavity, and replaced it with our Nu-Wool cellulose. The homeowner said it felt like a brand-new home.” – Joseph Wolf
Step-by-Step: What to Do If You’ve Had a Pest Infestation
Step 1: Confirm Pest Removal
Before we can address your insulation, make sure the pest control professionals have resolved the infestation. We do not remove rodents—but we specialize in restoring your insulation afterward.
Step 2: Schedule an Attic or Crawlspace Assessment
We’ll inspect the space—and can add a thermal-camera energy audit—to assess:
- What kind of damage occurred
- Whether insulation needs full or partial removal
- Signs of moisture or mold left behind by the pests
Step 3: Safe Insulation Removal
Using our dedicated vacuum truck, we remove contaminated insulation without spreading debris into your living space. Our team wears full protective gear and follows strict protocols.
Step 4: Sanitize and Air Seal
We apply an EPA-approved sanitizer if necessary and perform our signature AIRLOCK Air Seal process to close off any entry points or air leaks.
Step 5: Install New, Pest-Resistant Cellulose Insulation
Our Nu-Wool premium cellulose is:
- Mold-resistant
- Treated with borates (natural pest deterrents)
- Non-toxic, safe for families and pets
We blow it in evenly, creating a seamless barrier that performs better than traditional fiberglass.
Why Not Just Leave the Old Insulation?
Many homeowners are tempted to skip insulation removal to save money. But here’s why we strongly advise against it:
| Problem | Consequence |
| Contaminated insulation | Foul odors, health risks from droppings |
| Gaps from nesting | Reduced energy efficiency |
| Ongoing infestation | Unsealed gaps may allow pests to return |
| Mold risk | Moisture and droppings accelerate mold |
Leaving damaged insulation is like leaving old garbage in your attic—it festers and works against your comfort and health.
Common Questions We Hear
“Can you remove fiberglass insulation contaminated by mice?”
Yes. In fact, fiberglass is often the first material to be chewed through or tunneled into. We safely remove and replace it with cellulose.
“Do I need to replace all my insulation?”
Not always. If only a portion is affected, we can do a partial removal and blend in new material seamlessly.
“Will it happen again?”
We work with local pest control pros and use sealing techniques to help prevent recurrence. Our cellulose insulation also includes borate treatment, which pests hate.
Real Story: When One Mouse Turned Into a Mess
In Lake County, we visited a home where mice had chewed into a crawlspace corner. The homeowner had no idea until the smell hit them upstairs. Our crew removed the ruined fiberglass, cleaned and sealed the joist bays, and replaced it with dense-packed cellulose. Their words? “It’s finally quiet, clean, and doesn’t stink anymore.”
