The critters are gone. The mess in your attic isn’t.
Scratching in the ceiling at night, a musty smell in the upstairs hallway, droppings on the attic hatch: once the wildlife company has done its job, you’re still left with rodent-damaged insulation. Matted, tunneled, and soaked with urine, it doesn’t insulate well and it can keep smelling for years.
Sean, Caleb, and Luke handle the part that comes after trapping and exclusion. We tell you honestly whether the damage is a small area we can clean and patch or a whole attic that needs insulation removal, then we seal the gaps that let the animals in and blow in fresh attic insulation.
🔍 Signs Your Attic Insulation Has Rodent Damage
- Droppings on the attic floor, around the hatch, or along the top of exterior walls.
- A stale, ammonia-like odor near the attic access or in upstairs closets, especially on hot days.
- Tunnels, trails, and flattened spots in blown-in insulation, or batts pulled out of place.
- Nesting material such as shredded insulation, paper, or leaves piled near the eaves.
- Chewed wires, flex ducts, or bath-fan hoses. Raccoons and squirrels will tear into ductwork.
- Rooms that suddenly feel hotter or colder, because packed-down insulation loses much of its value.
🧭 The Right Order: Trap, Exclude, Clean, Seal, Re-Insulate
Wildlife Control
A licensed wildlife or pest pro removes the animals and closes the main entry points. We coordinate with your wildlife company or can suggest one.
Free $0 Inspection
We go up, photograph the damage, and show you whether you need spot cleanup or full removal.
Removal & Sanitizing
Soiled insulation is vacuumed out through hoses to sealed bags outside; the attic floor is sanitized and deodorized as needed.
Seal the Gaps
With the attic floor bare, we foam-seal top plates, wire holes, and gaps around pipes and flues that let air and pests move around.
Fresh Insulation
We install rafter baffles and blow fresh fiberglass or borate-treated cellulose to 18–22 inches (R-49–R-60).
Damaged ductwork is common after raccoons. One Overland Park homeowner put it this way on Google: *”Installed new and upgraded insulation in the attic of our 3,400 sq ft home, and repaired ductwork in upstairs rooms damaged by raccoons. Very pleased!”*
⚖️ Spot Cleanup or Full Removal? We’ll Show You
Not every rodent problem means tearing out the whole attic. Mice often stay along a few runways near the eaves, while raccoons and bats tend to use one area as a latrine. When the damage is confined, we remove and replace just that section, seal the entry points, and top up the rest of the attic.
A full tear-out makes sense when droppings and urine are spread across the attic, the smell has soaked in, or the insulation is wet or crushed everywhere. In that case we follow our no-mess Attic Cleaning & Insulation Removal process and finish with new insulation. Either way, you’ll see photos before you decide.

💰 Rebates on the Re-Insulation
Cleanup itself usually isn’t what utility programs pay for, but the air sealing and new attic insulation that follow can qualify. We help Missouri homeowners with Evergy Missouri, Spire, and PCEC programs and Kansas homeowners with Evergy Kansas programs where applicable, and we’ll check your eligibility during the inspection.

❓ Rodent-Damaged Insulation FAQ
Do you trap or remove the animals?
No. We focus on the insulation, sanitizing, and sealing after a wildlife control professional has removed the animals and closed the main entry points. We’re happy to coordinate with your wildlife company.
Can I just leave the old insulation and add new on top?
If droppings are limited to a small area, we can often clean that section and top up the rest. If urine and droppings are spread throughout, covering them up traps the odor and contamination, so removal is usually the honest answer.
Is it safe to clean up mouse droppings myself?
For a few droppings in a garage, follow the CDC’s wet-cleaning method: gloves, ventilation, disinfectant, and paper towels, with no sweeping or vacuuming. A whole attic of soiled insulation is a different job and is best left to a crew with the right equipment and protection.
Will the smell go away after cleanup?
Removing the soiled insulation takes away most of the source. We also sanitize and deodorize as needed and seal gaps so attic air isn’t pulled into your rooms.
How long does a rodent cleanup take?
It depends on attic size and how much needs to come out. Many jobs are finished in a day, and we’ll give you a timeline with your free quote.
