What's Included in Crawl Space Rodent Control
Crawl spaces need a different playbook than attics — low clearance, damp soil, and constant ground contact. Every job covers all four:
- Under-house trapping and removalWe place snap traps and live traps along foundation walls and pier footings where Norway rats and deer mice travel, returning until the space reads quiet. Low clearance means slow, careful work — we don't rush it.
- Vapor barrier repair and replacementRodents shred plastic sheeting into nesting material; we remove the ruined sections and lay fresh 6-mil poly, sealed at the seams and walls, so the ground stops feeding moisture upward.
- Foundation vent and access sealingWe replace rusted-out vent screens with galvanized hardware cloth and rebuild damaged crawl space access doors, closing the gaps rats have been using for years.
- Debris and nesting cleanupWe haul out nests, droppings, and old fallen insulation from the crawl floor, then spot-sanitize the worst areas so the space starts clean.
Crawl Space Rodent Control for Homes
Most Corvallis homeowners never go under their house — which is exactly why rodents love it down there. We do the crawling for you, document what we find with photos, and hand the space back sealed and dry.
- Ranch homes with shallow crawl spaces where Norway rats burrow under the footing
- Homes on sloped lots where one side of the foundation sits open to grade
- Older homes with original rusted vent screens rats push through
- Houses near fields or creeks where fall drives field mice under the floor
Crawl Space Rodent Control for Businesses
Strip malls, offices, and restaurants with crawl spaces face the same ground-level pressure — plus health inspectors who check under buildings. We work around business hours and provide the documentation inspectors ask for.
- RestaurantsWe clear rodents from under-kitchen crawl spaces and seal grease-area entry points that attract Norway rats.
- Small office buildingsWe protect subfloor wiring and plumbing runs that rodents damage out of sight.
- Daycares and clinicsWe use enclosed, tamper-resistant trapping under buildings where children and patients are above.
- Apartment buildingsWe coordinate with managers to treat shared crawl spaces without disturbing tenants.
What Is Crawl Space Rodent Control?
Crawl space rodent control removes rats and mice living under your home and repairs the damp, open conditions that drew them there. In the Willamette Valley, crawl spaces stay moist most of the year — and a wet, undisturbed space under a warm floor is ideal rodent habitat.
Norway rats burrow along foundation walls and chew through old vent screens, while deer mice slip through gaps you could barely see. They shred vapor barriers for nesting, foul subfloor insulation with droppings, and chew on plumbing and wiring in the dark. Because the damage hides under the house, most infestations are months old by the time anyone notices the smell.
What happens under the house doesn't stay under the house.
Our Crawl Space Rodent Control Process
Crawl space work is slower and more physical than attic work — here is the sequence we follow.
Under-house inspection
We crawl the full perimeter and interior, photographing entry gaps, burrows, damaged vapor barrier, and droppings trails. You get photos of a space you've probably never seen yourself.
Trapping along foundation runs
We set traps against foundation walls and around piers where Norway rats patrol, keeping poison out from under the house where it could wash into soil or reach pets. Return visits clear and reset until activity ends.
Vapor barrier and debris removal
We pull out shredded sheeting, nests, droppings, and fallen insulation, bagging everything for disposal before anything new goes down.
Sealing vents and access points
We fit galvanized screens over every foundation vent, rebuild the access door, and close pipe and conduit gaps with mortar and mesh.
Fresh barrier and final verification
We lay new vapor barrier, set monitor traps, and return to confirm the space is quiet. The job is done when the crawl space is clean, dry, and sealed.
Tools and Methods We Use
Low-clearance snap traps
Compact traps that fit in tight foundation runs where Norway rats travel; placed against walls, never in the open.
Tamper-resistant bait stations (exterior)
Locked stations placed outside the foundation to intercept rats before they reach the vents — never loose poison under the house.
6-mil polyethylene sheeting
New vapor barrier laid wall-to-wall over the crawl floor, lapped and sealed to cut ground moisture.
Galvanized hardware cloth
Rust-proof mesh cut to fit foundation vents and access openings; rats can't chew through it and it survives valley humidity.
Mortar and masonry sealant
Closes gaps where pipes and conduits pass through the foundation — the entry points caulk alone won't hold.
Headlamps and inspection cameras
Light every dark corner of an 18-inch crawl so nothing — burrows, nests, chewed lines — gets missed.
Full PPE with respirators
Crawl space air carries dust, mold, and droppings particles; we suit up for every entry.
Subfloor insulation supports
Wire stays and mesh that hold replacement batts tight to the subfloor so rodents can't nest behind sagging insulation.
When to Call for Crawl Space Rodent Control
Musty or animal smell rising through floor vents
Odor from below travels up through gaps around plumbing and ducts. We find the source under the house, remove it, and seal the air paths.
Noises under the floor at night
Scurrying beneath the floorboards means active rodents, often Norway rats. We trap the foundation perimeter and close their entries.
Torn vent screens or open access doors
A missing screen or a warped access door is a standing invitation. We rebuild the barriers and check whether anything already moved in.
Crawl Space Rodent Control, Done the Corvallis Way
Corvallis crawl spaces are a product of the valley: high water tables, winter rain that never quite stops, and older foundations built before modern vent standards. Many homes near the Willamette and Marys rivers sit on ground that stays damp into June, and a damp crawl space draws both rodents and the moisture that ruins wood. We plan every job for valley conditions — drainage-aware barrier work, rust-proof materials, and sealing that holds through flood-season humidity.
- Homes near the Willamette RiverHigh water tables keep crawl spaces damp, and damp soil is easy digging for Norway rat burrows.
- Older foundations near downtownUnlined vents and crumbling mortar give rats direct routes under the floor.
- Sloped lots on the west sideUphill foundations sit open to grade on the downhill side — a natural entry ramp for rodents.
- Homes backing onto fieldsFall harvest pushes field mice and rats toward the nearest warm crawl space.
- Mid-century ranch neighborhoodsOriginal vent screens have rusted through after fifty valley winters.
From problem to finished result.
Ranch home, damp crawl
BeforeThe owner smelled something foul through the floor registers every time the furnace ran, and the crawl space hadn't been entered in a decade.
AfterWe removed a Norway rat colony, replaced the shredded vapor barrier across the floor, and rescreened every vent.
A working vapor barrier cuts both moisture and rodent appeal.
Sloped-lot house
BeforeDeer mice were nesting in fallen subfloor insulation on the downhill side, where the foundation sat exposed to grade.
AfterTrapped and cleared, insulation re-secured, and the exposed grade sealed with mesh and mortar.
Walk your foundation line each fall — gaps show up after wet winters.
Downtown duplex
BeforeTenants complained of scratching under the floors; the landlord found a vent screen kicked in at the back.
AfterSpace cleared, access door rebuilt with a locking panel, and vents fitted with galvanized screens.
Locking access doors keep out both rodents and curious hands.
Problems Crawl Space Rodent Control Solves
Under-house rodents damage what you can't see — until the repair bill arrives.
Shredded vapor barriers and rising moisture
Rats tear plastic sheeting into nesting strips, letting ground moisture rise into joists and subflooring. We replace the barrier and stop the damp cycle that rots wood and feeds mold.
Fouled subfloor insulation
Mice and rats nest in the batts between your joists, compressing them and soaking them with urine. Heating costs rise while floors stay cold; we remove the ruined sections and secure fresh insulation tight.
Chewed pipes and wiring under the floor
Norway rats gnaw PEX lines, Romex, and low-voltage cable in the dark. We remove the rodents and flag every chewed run for your plumber or electrician before a leak or short finds you first.
A Dry, Sealed Space Under Your Home
Rodents gone, verified
Trapping runs until monitor traps sit quiet — not until we feel like stopping. You get the log to prove it.
Moisture under control
New vapor barrier and sealed vents cut the damp air that rots joists and invites the next colony.
Lower energy waste
Intact, properly secured subfloor insulation keeps heat in the house instead of leaking into the dirt below.
Documented for buyers and inspectors
Photos, sealing lists, and trapping logs give you paperwork that holds up at sale or inspection time.
What you receive
Clear records you can keep and share.
Trapping log
A written record of trap placements, visits, and every animal removed.
Sealing and barrier list
Every vent, gap, and barrier section we repaired, with materials noted.
Good to Know Before You Book
Three things that surprise Corvallis homeowners about crawl space jobs.
Crawl spaces take longer than attics
Low clearance and damp ground slow every step, so most crawl jobs run two to four weeks. The extra time is the work, not a delay.
Moisture and rodents are one problem
Fixing the rats without fixing the damp just invites the next colony. Barrier and vent work is part of rodent control, not an upsell.
You should see the photos
Ask any company to show you dated photos from under your own house. If they can't, they didn't do the crawl.

Typical crawl space jobs run $180–$450, with most landing mid-range once trapping and vent repairs are included. Full vapor barrier replacement or extensive sealing adds to that, and we'll price it line by line after the under-house inspection. You approve the number before we start.
Smells through floor vents, scratching under the floorboards at night, and unexplained spikes in heating bills are the classic signs. The surest check is a photo inspection — we crawl it with cameras and show you exactly what's living down there.
Yes, when rodents have shredded it — and they usually have. We remove the ruined sheeting, clear the debris, and lay new 6-mil poly sealed at the seams. An intact barrier is one of the best long-term rodent deterrents a crawl space can have.
Most crawl spaces here go quiet within two to four weeks of trapping, then we seal and verify. Damp ground and low clearance make this slower than attic work, but the monitor-trap confirmation is the same: no activity, no closure.
Yes — air moves upward from the crawl space into living areas through gaps around pipes and ducts, carrying dust, mold, and droppings particles with it. Clearing the rodents and sealing those paths makes a measurable difference in what your family breathes.
