Rat Control in Spokane, WA
Norway rats in the crawl space, basement, or under the deck? Get them removed and the entry points sealed before they chew wiring or spread through the house.
Rat control in Spokane means dealing with the Norway rat. This is the heavy, burrowing rat that digs along foundations, nests in crawl spaces and basements, and works the alleys and yards of older neighborhoods. It is the rat you find in Spokane, not the roof rat, because Inland Northwest winters run too cold for roof rats to establish. When you call 509-401-4897, a local rodent exterminator confirms it is rats, finds where they are living and getting in, and gives you upfront pricing before any work starts.
Rats are a bigger problem than mice for one reason: they gnaw. A Norway rat can chew through soft utility lines, subfloor, and wood framing, and their teeth never stop growing, so they never stop. Left alone through a Spokane winter, a small group under the foundation becomes a colony in the walls. Here is how the work goes.
How Norway rats get into Spokane homes
Rats need warmth and a way in, and Spokane's housing stock gives them both. On the South Hill, in Browne's Addition, and around the Perry District, century-old Craftsman and brick homes sit on basalt rock and mortar foundations that open small gaps as they settle through decades of freeze and thaw. A rat only needs a hole the size of a quarter.
The common entry routes a local technician checks first:
- Foundation and basement gaps. Cracks in rubble and rock foundations, gaps where the sill meets the stone, and old coal-chute or utility openings.
- Crawl-space vents. Torn or missing screens on the vents around the base of the house are a wide-open door.
- Under decks, porches, and sheds. Rats burrow into the soft, protected soil, then work their way toward the warm foundation.
- Utility penetrations. Gaps around water lines, gas lines, and electrical conduit where they pass through the wall.
- Garages and their connections. Under-door gaps and the wall shared with the house, common on newer builds in Spokane Valley and Mead.
Signs you have rats, not mice
Rats leave bigger, blunter evidence than mice. Droppings are capsule-shaped and up to three-quarters of an inch. You may see burrow openings two to four inches wide near the foundation, greasy brown rub marks along the paths they run, and gnaw damage on wood, plastic, and soft metal. The sound is heavier too: mice skitter, but rats thump and drag. If you are hearing something substantial in the crawl space or basement at night, it is worth a rat inspection.
How rat control works
Rats are neophobic, which means they avoid new things in their environment for days. That is why a snap of DIY traps often fails: the rats simply route around them. A local rodent exterminator works with that behavior instead of against it, placing the right equipment on established runways and burrow openings and giving it time.
The sequence that holds in Spokane: confirm it is rats and map the entry points, remove the active population with targeted trapping and follow-up checks, then seal every opening with rodent-proof, metal-backed material so the next group cannot move in. Skipping the sealing is the single most common reason rats come back the following fall.
Why sealing matters more with rats
A rat that can gnaw will reopen a soft patch, so the sealing has to be done with steel mesh, hardware cloth, and rodent-proof sealant, not foam or steel wool alone. That is the difference between a fix that lasts and one that fails by December.
It also protects the house. Rats chewing near wiring is a real fire risk, and burrowing under a slab or foundation undermines soil over time. Getting them out and closing the entry points is home protection, not just pest removal. Ask for the inspection first so the plan matches your specific foundation and layout, and pair it with exclusion and sealing for a result that holds.
Spokane rat control questions
Are the rats in Spokane roof rats or Norway rats?
Almost always Norway rats. They burrow along foundations and live low, in crawl spaces, basements, and yards. Roof rats, which climb and nest high, are rare in the Inland Northwest because the winters are too cold for them to establish.
How long does rat control take?
Removing an active rat population usually takes one to a few weeks of trapping and follow-up, depending on the size of the colony. The sealing can often be done alongside it. You get a timeline after the inspection.
Can I just use poison from the hardware store?
Rodenticide outdoors can send a rat to die inside a wall, creating an odor problem, and it poses a risk to pets and to the hawks and owls that hunt Spokane rats. A local technician can explain safer, targeted options for your property.
Will the rats come back?
Not through the same openings if they are sealed properly with metal-backed materials. Rats return when trapping is done without sealing, because the entry points are still open for the next group the following winter.
