Rat extermination deals with rats that have moved into your Olympia home. A local provider first identifies which rat you have — roof rats, which nest in attics and rooflines, or Norway rats, which burrow and nest in crawl spaces and basements — then sets a removal plan for the spaces where that species is active. The distinction matters because the two species travel different routes and need different trap placement and sealing.
Mice/rat control starts with the same question every time: how many rats, and where do they enter? Rats in crawl space areas leave larger droppings and heavier sounds than mice, while a rat in the kitchen usually means rats are already established in the walls or below the floor. Removal covers the rats present; sealing the gaps they used is what keeps new rats from replacing them, especially in older Olympia homes near the waterfront and greenbelts.
What rat extermination includes
- Identification of the rat species — roof rat or Norway rat — and where it is active
- A removal plan fitted to attics, rooflines, crawl spaces, basements, or kitchens
- Trapping placed along rat runways, out of the way of children and pets
- Sealing of ground-level and roofline entry points after removal
- Cleanup advice for droppings and nesting material left behind
How it works
Call (360) 812-9464 and describe what you have seen — droppings, sounds, or a rat itself. We connect you with a local Olympia provider.
The provider inspects the attic, roofline, crawl space, and kitchen to confirm the species and map activity and entry points.
Traps are placed along rat runways and checked, and captured rats are removed.
Entry points are sealed at ground level and roofline, and the provider explains what to watch so new activity is caught early.
Rat Extermination in Olympia
Olympia's waterfront and older neighborhoods give rats steady opportunity. Norway rats burrow near foundations around West Bay and downtown, while roof rats use trees and rooflines to reach attics in leafy areas like the Eastside and Bigelow Highlands. The wet climate keeps shelter valuable year-round, so a home with open ground-level gaps or overhanging branches can draw rats in any season. That is why rat work here pairs removal with sealing at both levels — ground and roofline — rather than trapping alone.
Keeping rats from coming back
Removal clears the rats present, but two habits decide whether they return. The first is the roofline: overhanging branches and vines give roof rats a bridge to attics, so trimming limbs back from the roof and sealing roofline gaps and attic vents closes the high route. The second is the ground: burrows near foundations, low openings, and gaps where utilities enter give Norway rats their route, so sealing at ground level and clearing harborage close to the foundation closes the low route.
Both levels matter in Olympia, because the city holds both species. A home that seals only the roofline may still admit Norway rats at the foundation, and a home that seals only the ground may still admit roof rats from above. Pairing removal with sealing at both levels, then watching the attic, crawl space, and kitchen edges for fresh signs, is what keeps a rat result from being a single-season fix.

Rat Extermination questions, answered
How do I know if I have rats or mice?
Droppings are the clearest clue: rat droppings are larger than mouse droppings, and rat sounds in a crawl space or attic tend to sound heavier than the light scratching mice make. A rat in the kitchen or rats in crawl space areas usually point to rats, while small droppings in pantries point to mice. An inspection confirms which rodent you have, because trap size, gap size, and the areas to check all differ.
What is the difference between roof rats and Norway rats?
Roof rats are slimmer, agile climbers that nest in attics, trees, and rooflines, reaching the house from overhanging branches and upper gaps. Norway rats are larger, ground-dwelling rats that burrow and nest in crawl spaces and basements, travelling along the ground and through low openings. The species decides whether the work focuses on the roofline or the ground level.
How does rat extermination work?
A provider first inspects to confirm the species and map activity, then places traps along rat runways — attic beams, roofline gaps, crawl space edges, and kitchen routes — checks them, and removes captured rats. After removal, entry points are sealed so new rats cannot follow the same routes.
Do I need sealing as well as removal?
Yes, in most cases. Removing rats without sealing the gaps means new rats follow the same routes, often within the same season. Sealing at ground level for Norway rats and at the roofline for roof rats is what makes the result last.
What should I do if I see a rat in my kitchen?
Do not ignore it — a rat in the kitchen usually means rats are already established in the walls, attic, or crawl space. Note where and when you saw it, check for droppings nearby, and call (360) 812-9464. The details you report help the provider plan the inspection and come prepared.
