Why this step comes last.
A cleanup done while animals are still coming and going is wasted effort. They simply foul the clean space again. For that reason sanitizing follows trapping and sealing, and it only begins when the technician has confirmed the structure is empty.
When the time comes, the work is methodical. Protective gear goes on, the space is ventilated and the contaminated material is lifted out wet and bagged. Only then can the underlying surfaces be treated.
What gets removed and what stays.
- Bags receive pellets, urine-soaked insulation and nest mats.
- Insulation that is stained or matted flat gets replaced.
- Sound wood, ductwork and vapor barriers are cleaned where they sit.
- Broken ducts are marked for repair and never covered over.
The estimate separates each of these so you can see what is removed and what is saved.
The method, in order.
| Stage. | What happens. | Reason. |
|---|---|---|
| Ventilate. | Open hatches and vents, wait thirty minutes. | Reduces stale air before work begins. |
| Wet. | Drench pellets and nesting with disinfectant. | Keeps dust from rising. |
| Remove. | Lift material into heavy bags, then double bag. | Contains waste during carrying. |
| Treat. | Disinfect exposed wood, ducts and barriers. | Reduces germs and odor. |
| Restore. | Fit new insulation or baffles. | Returns the space to working order. |
For small jobs you might do yourself, the CDC box further down walks through the same order.
Homes with tile roofs, vaulted ceilings and tight attics.
Some houses in the area have attic spaces that are hard to enter, such as low-clearance crawlways above vaulted rooms. We have no survey of which ones do. When access is difficult, the estimate notes it, and the technician may need extra time and different equipment.
If you can reach the hatch, take photographs of what you see without entering. They help the technician plan before the visit.
What to do before the crew arrives.
- Open a way to the hatch and have a sturdy ladder ready.
- Hold children and pets back from the work zone.
- Cover stored items you want to protect.
- Note any insulation type you know of, such as batts, blown-in or foam.

A wet-wipe routine for pellets and nests.
Many homeowners handle small cleanups themselves, even when a technician is on the way, so keep these precautions nearby.
- A single dry pellet can crumble at a touch and release a cloud you cannot see.
- Plan on half an hour of airing before any wiping begins.
- Gloves belong on your hands before you touch the spray bottle.
- Let the liquid sit for around five minutes; the wait does the disinfecting.
- Seal the bag before washing your hands.
- Scrub under the fingernails and up the wrists, then use a fresh towel.
