Rats and mice mark their paths with urine. Even after they are gone, those scent trails remain in the wood, drywall, and insulation, and they lead the next rodent right back to the same entry points and nesting spots. Attic decontamination breaks those markers down and removes the odor, so the space stops advertising itself.
What Decontamination Does
- Neutralizes urine and odor. We use enzyme-based treatments that break down the compounds in rodent urine rather than covering them with fragrance.
- Sanitizes surfaces. The attic floor, framing, and any exposed drywall are treated after debris is cleared.
- Removes scent trails. Rodents follow scent. Erasing it makes your attic far less likely to be picked by the next one looking for a place to nest.
When You Need It
Decontamination is the step after rodents are out and debris has been cleared. It usually follows attic and basement cleanup or insulation removal, and it comes before new insulation goes in.
You probably need it if:
- There is a lingering ammonia smell upstairs or near ceiling vents
- You see stains on the attic floor, framing, or ceiling drywall
- The attic had an active infestation for more than a few weeks
Dead Rodent Odor
A strong, sweet, rotting smell usually means a rodent died inside a wall, under insulation, or in a duct. Decontamination alone will not fix that. We locate the source, remove it, and then treat the area.
Sealing Comes First
There is no point decontaminating an attic that rodents can still get into. We make sure rodent proofing is done at every opening first, and our sealing work carries a 2-year warranty.
