After the Exterminator Leaves
The exterminator killed the rats. Congratulations. Now you have a crawlspace full of droppings, shredded insulation, and nesting material that smells like something between wet dog and death. The exterminator doesn't clean that up. That's a different job entirely.
Pest debris removal sits in an awkward gap between pest control and junk removal. Most exterminators won't touch it. Most regular cleaners won't either — and honestly, they shouldn't without proper protection. This is one of those jobs where cutting corners can literally make you sick.
Why You Shouldn't DIY This
Rodent droppings carry hantavirus. That's not a scare tactic — the EPA explicitly warns against sweeping or vacuuming mouse droppings because it aerosolizes the virus. One deep breath of contaminated dust and you're looking at a serious respiratory infection.
Oregon's wet climate makes this worse. Moisture plus rodent waste creates mold conditions fast. A garage that had rats for six months doesn't just have droppings — it has contaminated insulation, chewed wiring insulation, and possibly mold colonies growing on nesting material.
Proper removal requires:
- N95 respirators minimum — P100 for heavy contamination
- Disposable gloves and coveralls
- Wet-down method — spray droppings with disinfectant before disturbing them
- HEPA-filtered equipment if vacuuming is necessary
- Proper disposal — contaminated materials go in sealed bags
A professional crew doing a garage cleanout after a rat infestation runs $300 to $800. An attic or crawlspace is $500 to $1,500 due to access difficulty. Compare that to a hospital visit for hantavirus pulmonary syndrome.
What Actually Needs to Come Out
After a rodent or pest infestation, here's what typically gets removed:
- Contaminated insulation — rats love fiberglass batting, and once they've nested in it, the whole section needs replacement
- Nesting material — shredded paper, fabric, cardboard, leaves, whatever they found
- Droppings and urine-soaked materials — drywall, subflooring, stored items
- Damaged stored goods — boxes of clothes, holiday decorations, documents that got chewed through
- Dead animals — in walls, under floors, in HVAC ducts
The stored goods are the heartbreaker. People keep boxes in garages and attics for years, then discover rats turned grandma's quilt collection into a nest. Those items are gone. Getting them removed quickly at least stops the contamination from spreading.
Crawlspaces and Attics: The Hard Jobs
A garage infestation cleanup is straightforward — back up a truck, load it, go. Crawlspaces and attics are a different beast.
Oregon homes, especially older ones in Portland and Eugene, have crawlspaces that are 18 to 24 inches high. Pulling contaminated insulation out of a space you can barely fit into, wearing a respirator, in July — that's not a DIY project. It's barely a two-person job.
Attic access is usually through a tiny hatch. Everything removed has to fit through that opening or get bagged and passed down. A full attic cleanout after a raccoon infestation (yes, raccoons in attics are common in the Portland metro) can take a full day and fill two truckloads.
Budget $1,000 to $2,500 for crawlspace work and $800 to $2,000 for attic cleanouts. The price reflects the difficulty, not just the volume.
Preventing Round Two
Removing the debris is only half the job. If you don't address how they got in, you'll be doing this again in six months.
After the cleanout, seal every entry point. Mice fit through holes the size of a dime. Rats need a quarter-sized gap. Common entry points in Oregon homes: where utility lines enter the foundation, garage door seals, dryer vents without proper covers, and gaps where rooflines meet siding.
Steel wool packed into gaps, hardware cloth over vents, and spray foam for irregular openings. Your exterminator should handle exclusion work, but verify it's actually done. Walk the perimeter yourself.
For properties with recurring pest problems — especially rural properties in Lane County or older homes in inner Portland — consider an annual inspection and preventive cleanout of vulnerable areas. A $200 annual maintenance visit beats a $1,500 emergency cleanout every time.
