What's Included in Rat Control and Removal
Rats are bigger, bolder, and harder to fool than mice — this service is built specifically for them.
- Species IdentificationNorway rat or roof rat? We confirm the species from droppings, rub marks, and burrow patterns, because the trapping strategy changes completely.
- Colony Trapping ProgramRat-sized snap traps and secured stations placed along established runways, serviced until activity stops — never a single trap and a shrug.
- Burrow and Harborage TreatmentExterior burrows get treated and collapsed, and yard harborage like woodpiles and dense ivy is flagged for removal.
- Heavy-Duty ExclusionRats chew through plastic and weak mesh, so we seal with galvanized hardware cloth, metal flashing, and concrete-grade sealant.
Rat Control and Removal for Homes
Homes give rats everything they want: warm attics, food in kitchens and pet bowls, and quiet wall voids for nesting. Our residential rat work focuses on finding every nest — attic, crawl space, or garage — and cutting off the routes between them.
- Rats scratching in the attic or walls at night
- Burrows appearing along foundations or under porches
- Fruit or nut trees with gnawed, hollowed produce
- Droppings larger than a grain of rice near food or water
Rat Control and Removal for Businesses
Restaurants, warehouses, and farm-adjacent businesses face Norway rat pressure from the ground up. We combine burrow treatment with structural exclusion and keep the documentation your inspectors expect.
- RestaurantsDumpster-area burrow treatment and kitchen exclusion that hold up under health inspection.
- WarehousesPerimeter burrow work and dock sealing for facilities storing food, grain, or pet supplies.
- Farms and OutbuildingsBarn and outbuilding programs that account for constant re-pressure from surrounding fields.
- Apartment ComplexesCoordinated trapping and exclusion across units, with tenant communication handled for you.
What Is Rat Control and Removal?
Rat control and removal is the species-specific process of eliminating Norway rat or roof rat infestations and preventing their return. Because rats are larger, warier, and stronger than mice, the traps, bait stations, and exclusion materials must all be rated for rats — mouse-grade gear simply does not hold them.
Both species thrive around Corvallis. Norway rats burrow along the Willamette and Marys Rivers, under porches, and in crawl spaces, while roof rats climb mature trees, fences, and power lines to reach attics in older neighborhoods. Fall rains drive both indoors, and a single overlooked entry point can sustain a colony for months.
Trap the rats you see and seal the routes of the ones you don't — that's the whole job.
Our Rat Control and Removal Process
Rats learn fast and avoid new objects — our process is designed to outsmart that caution.
Species and Colony Assessment
We identify Norway versus roof rat from droppings, burrows, and rub marks, then estimate colony size from activity signs — the plan depends on getting this right.
Pre-Baiting and Trap Placement
Unset traps go out first so wary rats get comfortable feeding around them; once they are feeding confidently, traps are set along the same runways.
Active Trapping Phase
We return on a tight schedule to clear traps, reposition them as the colony shifts, and track declining activity until the last rat is out.
Burrow Treatment and Exclusion
Exterior burrows are treated and collapsed while entry points get rat-proof sealing — galvanized mesh, flashing, and metal kick plates where gnawing was worst.
Monitoring and Confirmation
Monitoring stations stay in place after trapping ends to confirm the colony is gone, and your final report documents every step for your records.
Tools and Methods We Use
Rat-Sized Snap Traps
Heavy-duty traps with the striking power to kill a Norway rat instantly — placed in attics, crawl spaces, and along exterior runways.
Locking Rat Bait Stations
Large tamper-resistant stations anchored outdoors, holding bait blocks sized for rats and secured against kids, pets, and raccoons.
Burrow Probes
Slender rods that map the direction and depth of Norway rat burrow systems before treatment, so no tunnel entrance is missed.
Heavy-Gauge Hardware Cloth
Galvanized steel mesh that rats cannot chew through, used over vents, foundation gaps, and crawl space openings.
Metal Flashing
Sheet metal shaped over gnawed door frames, corners, and eave gaps — a surface rats cannot chew back through.
Concrete-Grade Sealant
Tough exterior sealant that locks exclusion materials in place and stands up to Oregon's wet winters.
UV Tracking Light
Ultraviolet inspection that exposes rat urine trails and rub marks along baseboards, pipes, and beams.
Heavy-Pack Copper Mesh
Densely packed copper wool for larger pipe chases and foundation voids — it fills the gaps rats widen with their teeth.
When to Call for Rat Control and Removal
Scratching in the Attic at Night
Heavy scratching overhead usually means roof rats nesting in the attic or wall tops. We trap the colony, remove nesting material, and seal the roofline gaps they climbed through.
Burrows Around the Foundation
Norway rats dig burrow systems with multiple entrances along foundations, porches, and sheds. We treat the burrows, collapse the tunnels, and cut off their indoor access.
Gnawed Fruit or Garden Produce
Hollowed-out fruit on the ground or gnaw marks on tree bark point to roof rats working your yard. Yard trapping plus tree-trimming guidance pushes them out for good.
Rat Control and Removal, Done the Corvallis Way
Corvallis gives rats two perfect habitats, and we plan for both. Norway rats follow the Willamette and Marys River corridors, burrowing into yards and crawl spaces in riverside neighborhoods — so riverside properties get exterior burrow treatment as standard. Roof rats ride the mature tree canopy in older neighborhoods like College Hill and South Corvallis, crossing from branches to rooflines — so we always check what overhangs the roof. Fall's first heavy rains flood burrows and push both species indoors at once, which is why October callers get priority scheduling.
- Riverside NeighborhoodsHomes near the Willamette and Marys Rivers face the heaviest Norway rat pressure; exterior stations and burrow treatment are part of the standard plan.
- College Hill and Older NeighborhoodsMature trees and aging rooflines make these blocks prime roof rat territory — attic inspection starts with the trees.
- South CorvallisOlder foundations and detached garages give rats multiple entry options; we map and seal every one.
- Orchard and Garden PropertiesFruit trees, nut trees, and vegetable gardens feed roof rats year-round; yard sanitation is part of the long-term fix.
- Farm-Edge AcreageProperties bordering farmland see constant Norway rat re-pressure; perimeter station networks hold the line between visits.
From problem to finished result.
Roof Rats in a College Hill Attic
BeforeThe homeowner heard heavy scurrying above the bedrooms and found hollowed-out fallen apples under the backyard tree — classic roof rat signs.
AfterAttic trapping cleared the colony over two weeks, and we sealed the eave gaps where overhanging branches had given rats roof access.
Prevention tip: prune branches well back from the roofline — roof rats prefer to stay off open ground.
Norway Rats Under a Riverside Porch
BeforeBurrow holes ringed the back porch of a home near the Marys River, with droppings appearing in the crawl space.
AfterBurrow treatment and crawl space trapping eliminated the colony; we screened the crawl space vents and sealed the porch foundation gaps.
Prevention tip: pick up fallen fruit daily during harvest season — it draws rats in from the riverbanks.
Rats in a South Corvallis Garage
BeforeGnawed dog food bags and droppings along the garage walls signaled a Norway rat nest behind stored boxes.
AfterTrapping along the wall runways cleared the nest in a week, and metal kick plates plus a new door sweep closed their entry.
Prevention tip: store pet food and birdseed in sealed metal containers, never in the original bags.
Problems Rat Control and Removal Solves
Rats cause the costliest rodent damage of any species — and carry the most serious diseases.
Structural Gnawing
A rat's teeth never stop growing, so it gnaws constantly — through wood framing, PVC pipes, and electrical wiring. Norway rats have flooded crawl spaces by chewing through water lines; roof rats have sparked attic fires the same way. Removing the colony stops the damage at its source.
Disease Exposure
Rats spread leptospirosis through urine in damp areas like crawl spaces, and salmonella through droppings near food. Their parasites can also carry disease into the home. Professional removal plus sanitation guidance breaks every one of those transmission paths.
Rapid Reinfestation
Rats breed quickly and follow scent trails, so a half-finished job just invites the next colony. Species-correct trapping, burrow treatment, and rat-proof exclusion close the loop — the colony that is removed is the last one.
Rats Gone, Routes Closed, Done Right
Species-Correct Tactics
Norway rats and roof rats behave nothing alike, and we do not treat them alike. Your plan matches the actual animal in your building — which is why it works the first time.
Burrows Handled, Not Ignored
Exterior burrow systems get treated and collapsed, not just trapped around. That ends the outdoor colony feeding your indoor problem.
Rat-Proof Materials Only
Plastic mesh and foam alone will not stop a determined rat. We seal with galvanized metal, copper, and concrete-grade products rated for real gnawing pressure.
Proof It's Over
Monitoring stations confirm the colony is gone after trapping ends, and your final report documents the species, the work, and the warranty.
What you receive
Clear records you can keep and share.
Trap and Burrow Log
Dates, locations, and results for every trap and treated burrow on your property.
Exclusion Warranty Terms
The sealed entry points, materials used, and warranty coverage in plain language.
Good to Know Before You Book
Rat-specific knowledge that changes how you see the problem.
Rats Avoid New Objects
Rats are neophobic — they distrust anything new in their territory, including traps. That is why we pre-bait before setting traps, and why DIY trapping often fails for weeks.
The Yard Is Half the Job
Indoor trapping alone cannot beat an active outdoor colony. Burrow treatment, harborage removal, and yard sanitation are what keep rats from simply moving back in.
Roof Rats Rarely Touch the Ground
Roof rats travel along fences, wires, and branches, entering through the roofline. If your problem is overhead, the fix starts in the trees, not the basement.

Most rat jobs in Corvallis land between $180 and $450, covering species identification, trapping, burrow treatment, and entry-point sealing. Heavy infestations needing extensive exclusion or attic restoration can cost more — you will get the full written quote before we start. The price reflects a complete colony removal, not a per-trap charge.
Norway rats are burrowers — larger, ground-dwelling, and usually found in crawl spaces, basements, and along foundations. Roof rats are climbers — sleeker, excellent at scaling trees and wires, and most often found in attics and upper walls. The distinction matters because traps, bait placement, and exclusion points differ completely between the two.
We start by confirming whether they are roof rats, then place rat-sized snap traps along their attic runways — pre-baiting first so wary rats feed confidently. Once trapping clears the colony, we seal the roofline and eave gaps they climbed through and advise on safe cleanup of droppings and nesting material. Most attic jobs resolve within two to three weeks.
They can be. Rats contaminate food and surfaces with droppings and urine, spreading salmonella and leptospirosis, and their constant gnawing on wiring creates a genuine fire risk. They can also bite if cornered. Professional removal eliminates the colony quickly, and our exclusion work keeps the next one from moving in.
Not through the routes we seal — our exclusion work uses rat-proof materials and carries a written warranty. New rats can still arrive from neighboring properties, which is why we leave monitoring in place and give you a yard-sanitation checklist. Most clients stay rat-free for years with those basics in place.
