Why Exclusion Is the Most Important Step
Trapping Alone Doesn't Solve the Problem
Eugene's rodent population is large and established. When you remove rats or mice from a building without sealing their entry points, scout rodents from the same colony typically re-enter within 3–7 days. Permanent structural exclusion breaks this cycle by denying access at the source — the building's physical weak points.
In Eugene specifically, common entry points include deteriorating crawlspace vents (especially in homes built before 1980), gaps around utility conduit penetrations through the foundation, and open soffits or gable vents on older craftsman-style homes throughout neighborhoods like Cal Young, Friendly Area, and the Amazon District.
Our Exclusion & Proofing Process
Professional-Grade Materials, Permanent Results
We perform a full 360° exterior inspection of your home or business, documenting every gap ≥6mm. We then seal all identified entry points using materials rodents cannot chew through — hardware cloth, galvanized steel flashing, copper mesh, and commercial-grade expanding foam — matched to the specific location and vulnerability type.
- Full exterior audit — foundation, roofline, soffits, siding gaps, and utility penetrations
- Crawlspace vent replacement or screening with 1/4" galvanized hardware cloth
- Foundation crack and gap sealing with steel-reinforced caulk and copper mesh
- Pipe and conduit sleeve installation at all wall penetrations
- Soffit, fascia, and gable vent sealing or replacement where required
- Chimney cap and roof stack screening for roof rat prevention
- Photographic documentation of all work completed
Our Lifetime Warranty Guarantee
When you choose our full-structure exclusion service, we guarantee our seal work for the life of the materials. If rodents breach any of our sealed points, we return and re-seal at no charge. We're confident in our work because we use commercial-grade materials — not foam alone.
Common Entry Points on Eugene Homes
Where Rodents Get In
Crawlspace vents
Original mesh vents often corrode or are gnawed open — rats squeeze through gaps as small as 1/2".
Foundation gaps
Settlement cracks, weep holes, and utility conduit penetrations are prime entry points in Eugene's older housing stock.
Soffit and fascia
Rotted wood along roof edges gives roof rats direct access to attic space — common in homes with mature tree canopy.
Garage door seals
Worn rubber seals at the bottom and sides of garage doors leave gaps large enough for mice.
HVAC & plumbing lines
Any pipe or conduit entering through the foundation or wall without a sealed sleeve is an open invitation.
Dryer vents
Plastic louvered dryer vent covers are easily pushed open by rats — metal replacements with fine screening are required.
Pair Exclusion with Full Remediation
Seal the Building. Clean the Damage.
After a rodent infestation, contaminated insulation and waste material remain a health hazard even after the animals are gone. We recommend pairing exclusion work with our attic and crawlspace cleanout service for complete remediation.
