Slippery Rock University's Exclusion-First Rodent Team

Gnaw-mark size and dropping shape usually settle it, and the technician confirms on inspection. A full inspection covers roofline and chimney access alongside the foundation, since rodents use whichever gap is easiest.

Yes — trapping clears what's inside now, but sealing is what keeps the next one from moving in. A thorough seal job on the first visit is what actually prevents a second call a few months later, which is why we'd rather spend extra time sealing than rush to the next job.

Dry sweeping can release airborne particles, so it's safer to leave cleanup to the visit.

Most homes wrap in one visit for trapping and sealing, with a follow-up a week or two out to confirm.

Mechanical trapping and sealing come first, especially around pets and kids; bait stations are reserved for specific situations like commercial perimeters.

Pet food left out and gaps around utility lines are frequent culprits we flag on inspection. We recommend a seasonal walk-around of the foundation, since freeze-thaw cycles can open new gaps.
