Rodent control

Rodent control for rats and mice across Snohomish County.

We handle rats and mice for homes and businesses across Snohomish County and north King County, from Lake Stevens and Everett through Lynnwood, Edmonds, Bothell, and Kirkland. Good rodent control is bait and exclusion together: we seal the ways they're getting in, set tamper-resistant bait stations around the outside and refill them every time we come out, and trap the ones already inside when that's what it takes. With mild winters and this much cover, PNW homes get rodent pressure all year.

Rodents at a glance

What you need to know about rodent control.

Rodent control that lasts takes both halves. Bait keeps the population outside knocked down, and exclusion means the next one can't get in when it does show up. Do one without the other and you're either killing rats forever or sealing a house that already has rats in it. Roof rats come in high at the roofline, Norway rats come in low at the foundation, and mice need only a quarter-inch gap. We inspect inside and out, seal every opening, set locked bait stations around the exterior that get refilled at every visit, and trap indoors when there's activity to clear.

What we treat

What you're
actually dealing with.

Identification matters more than treatment. The same product on the wrong species can scatter a colony and double the problem. Here is what we typically find on calls in the Lake Stevens, Lynnwood, and Edmonds area.

Roof rats

These are the smaller, sleeker climbers that show up in attics and upper-story crawl spaces, and they're the most common rat call we get in Lake Stevens, Lynnwood, and Edmonds.

Norway rats

These are bigger and heavier and stay at ground level, burrowing under sheds, in drainage areas, and along foundations. They're more common in older neighborhoods with established trees and outbuildings.

House mice

These are small and gray and only need a quarter-inch gap to get in, and once one is inside, more are coming. We trap aggressively and find the entry point on the same visit.

Deer mice

These are less common indoors but turn up in detached garages and outbuildings. They can carry hantavirus, so cleanup isn't optional once we find a nest.

What to watch for

Signs you have
a real problem.

One sighting isn't always a problem, but a few of these together usually means it's time. We're happy to take a look and tell you what's going on.

  • 01

    Scratching, scurrying, or squeaking in walls or ceilings, especially at night

  • 02

    Small dark droppings near baseboards, behind appliances, or in cabinets

  • 03

    Gnawed wires, chewed insulation, or bite marks on plastic and wood

  • 04

    Greasy rub marks along baseboards on rodent travel routes

  • 05

    Pets fixated on an empty wall or corner

How we work

Our process
for rodents.

Every visit runs the same way: a real walk-through, a written report after every service, and warranty re-treatment at no charge, within 48 hours, if the pests come back between visits.

01

Inspect inside and out

We walk the attic, crawl space, garage, and full exterior. Identify rodent type, locate active nesting, and pinpoint every entry.

02

Seal them out

Close every gap a quarter-inch or larger with hardware cloth, sealants, and proper rodent-proof materials. No more reinforcements coming in while we work.

03

Bait, trap, and verify

Tamper-resistant bait stations go around the exterior and snap traps go in the active runways inside. We come back to check both, remove what we catch, and confirm the activity is gone. On recurring service we refill the bait every visit so the pressure never builds back up.

Why call us instead of DIY

Most rodent jobs fall apart at the same spot: somebody baited or trapped, but nobody closed the entry points, so it just opens a vacancy for the next rat. We do both halves. We seal the house up, keep bait stations working around the outside, and we don't call it done until we've confirmed the activity is actually gone.

Do you use bait or traps for rats and mice?

Both, because they do different jobs. We place tamper-resistant bait stations around the outside of the house and refill them every time we come out, which keeps the outdoor population down so there is less pressure on your home. Inside, we snap-trap the confirmed runways and remove what we catch. The bait is an anticoagulant, essentially a blood thinner, and rodents that feed on it dehydrate and tend to move off away from the structure rather than settling deeper into it.

How much does rodent control cost?

It depends on how the rodents are getting in and how much sealing the house needs, so we quote it after the inspection. A straightforward mouse job in a newer home is very different from sealing an older home with a wide-open crawl space. You get the price before we start any work.

What is the fastest way to get rid of mice?

Snap traps in the active runways clear the mice already inside within a week or two, but speed is not the point if you skip the exclusion. As long as the entry points are open, more keep coming. We seal first so the trapping actually finishes the problem instead of running forever.

How are rats getting into my attic or crawl space?

Roof rats almost always enter at the roofline through gaps at the eaves, vents, and roof penetrations. Norway rats come in low, through foundation gaps and crawl-space vents. We inspect both and identify which one you have before we close anything up.

How long does it take to get rid of rats?

Most homes are clear within a couple of weeks. We exclude the entry points first so no new rodents come in, then trap the ones already inside and return to verify. We do not close the job until two consecutive checks come up empty.

Is rodent control safe for pets?

Yes. The bait stations we use are tamper-resistant and locked, they sit outside the home, and only a rodent can get to what is inside one. There is no loose bait anywhere a dog or a cat can reach. Traps go where rodents travel, not where your pets go, and we will show you exactly where everything is placed before we leave.

Do you seal the entry points or just trap?

We seal, and it is the step most companies skip. Baiting or trapping without exclusion just opens a vacancy for the next rat. We close every gap a quarter inch or larger with hardware cloth and proper rodent-proof materials, clear whatever is already inside, and keep the exterior baited so the pressure stays off the house.
