Rat Control in Steilacoom, WA

Two species matter in western Washington. Norway rats dig burrows and stay near the ground, while roof rats climb well and use fences, wires and limbs to reach an attic. Which one you have decides where the technician starts, and the evidence generally settles it.

Steilacoom lies on Puget Sound, and some lots have water on one side and tall trees on another. That fact does not prove your house has rats, and we never assume it. It means the inspection reads the edge of the lot and the roofline together, as animals might arrive from either side.

Rat pellets are clearly bigger than mouse pellets and tend to pile along a regular path. Teeth marks are bigger as well, and a rat can chew through lumber, vinyl siding or thin sheet metal. Oily streaks on a beam, pipe or fence rail mark the lane it runs every night.

Photograph the evidence before moving any of it. A picture taken beside a coin tells the technician how big the pellets are.

Rats shy away from anything new. Traps may be placed unarmed or covered for a day or two, then armed once the animals ignore them. That patience explains why a rat job often takes more than one visit, and we describe the schedule at the start.

Boxed snap traps and enclosed stations follow the routes the evidence shows. Each sits beyond the reach of kids, pets and wild animals, and we tell you its location. Nothing is left behind unrecorded.

When the catches taper off, the openings are closed with metal flashing, heavy mesh and sealant. A rat enlarges a hole by gnawing, so soft materials give way. Our rodent exclusion page lists what we use and why.

• Roofline gaps, soffit corners and unscreened vents.
• Crawl space screens that have rusted or been pushed inward.
• Utility entries where a cable or pipe passes through the wall.
• Garage door corners and the sill beneath a side door.

What happens outdoors decides whether more rats follow. Pet food, windfall fruit, compost and bird feeders are all meals, and thick plantings against a wall are cover. The yard half of the job lives on the backyard and outdoor rodent control page.

Mention it if you keep chickens or store feed. Feed rooms and coops draw rats, so the plan adds metal bins and tidy habits to the traps.

A clear house means silent nights, no fresh pellets and empty traps. If insulation or ducts were fouled, the next stop is attic and crawl space cleanup. If you are not even sure the animal is a rat, begin with an inspection.
