Norway rats, roof rats and house mice — the Puget Sound region's most persistent structural pest.
Peak months: September, October, November, December, January, February.
We walk the roofline, foundation, crawl space and attic and map every active entry point — not just the room where you heard them.
Targeted trapping placed on actual runways. We prefer mechanical control indoors so nothing is left to decompose in a wall.
Gaps get sealed with rodent-proof materials: metal mesh, hardware cloth and mortar rather than expanding foam that gets chewed straight through.
Contaminated insulation can be removed, the space treated, and new insulation installed so the attic stops smelling like an invitation.
Follow-up visits confirm the activity stopped. On commercial sites, connected SMART devices report activity continuously.
None of this replaces treatment, but all of it makes treatment hold longer. Most of it costs nothing.
They climb. Roof rats travel along fences, branches and downspouts, then enter through gaps at roof-to-wall junctions, vent screens and gable ends. A quarter-inch opening is enough for a mouse; a half-inch for a rat.
We place devices in areas pets and children cannot reach, and we tell you exactly where each one is before we leave. If placement in a shared space is unavoidable, we use tamper-resistant stations.
Most homes see activity drop within the first one to two weeks. Exclusion work is what makes it permanent — trapping alone only handles the animals already inside.
Tell us what you have seen and we will confirm whether it is rats & mice — and what it takes to keep it gone.
