Why cleanup waits.
It is tempting to start with the mess. Droppings are visible, the smell is bad and the insulation looks ruined. But if animals still use the space, any clean material is fouled within days, and disturbing nests can push them deeper into walls.
So the order is trapping, then sealing, then cleanup. Our exclusion work and trapping logs tell us when the space is safe to treat.
Protecting the people doing the work.
Rodent waste dries into fine dust that can carry germs. The CDC sequence begins with airing out a shut space, then soaking droppings in disinfectant, waiting, and wiping with towels that end up in a sealed bag. A broom or vacuum is the wrong choice for dry waste.
Technicians wear gloves and respirators, work with the space ventilated and keep the area wet while they collect waste. Nobody should be in the attic without a plan, and we ask that you stay out of it during cleanup.
What gets removed and what stays.
- Heavily soiled loose-fill or batt insulation, bagged on site.
- Nests, droppings and urine-stained material from joists and floors.
- Gnawed vapor barrier or duct wrap that cannot be reused.
- Insulation with only light contamination, when it can be treated and left in place.
The line between removing and treating depends on how much waste is present and how deep it reaches. We show you the condition before and after, and the written scope lists each choice separately.
| Space. | Typical challenge. | How we approach it. |
|---|---|---|
| Attic. | Loose insulation spread with droppings and nest piles. | Wet collection, bagging, then treatment of surfaces. |
| Crawl space. | Low clearance and damp ground. | Careful access, moisture check and vapor barrier review. |
| Wall void. | Waste inside a closed cavity. | Targeted access only where it is justified. |
| Cellar. | Stored boxes and uneven floors. | Clear, clean, then discuss shelving or storage changes. |
Smells and moisture.
Rodent urine and decay can leave odor in wood and insulation, and moisture makes it worse. Cold climates add a wrinkle: a poorly vented attic can collect condensation in winter, which dampens insulation and spreads odor. We note signs of moisture and flag them for a roofer or insulation specialist.
Snap a picture of the droppings or gnaw marks and mention it when you call, which speeds up the visit.
Dial (888) 686-4821When the cleanup is done.
Once the area is treated and dry, replacement insulation can go in. Photos before and after, a list of what was removed and a final check are part of the visit. If anything about the building raises a separate concern, such as damp framing, we tell you and do not guess.

Before you call, a quick health checklist
These steps need no phone call. They are the same ones agencies give anyone who finds droppings at home.
- Dry sweeping looks harmless and still launches particles that drift for a long while.
- Stale, closed air holds whatever floats in it, so let a long-shut room breathe before you begin.
- While gloved, keep your hands off your face, and wash up once the gloves are off.
- The rhythm is spray, wait, wipe, with around five minutes in the middle.
- Knot the bag, bin it, then wash your hands again.
- For a few weeks, keep an eye on how you feel, and tell your doctor about flu-like symptoms or hard breathing.
