When fall and winter arrive in Tumwater, you may hear scratching in the walls, find small droppings under the sink, or spot chewed food packages. These early signs show rodents want shelter inside. Our damp climate and dense vegetation in Olympia and Thurston County create an ideal habitat for rats, mice, and other small wildlife.
The most common rodents in Tumwater homes are Norway rats, roof rats, deer mice, and house mice. They get in through crawl spaces, gaps around pipes, or roof vents to find warmth and food. You may also see voles in lawns and chipmunks at feeders. Raccoons may pass through outer neighborhoods.
If you’re already seeing signs of activity, professional rodent control in Tumwater, WA, can stop damage early and keep your home safe. This guide explains common rodent species, why they are a problem, and how pest experts protect your home.

Norway Rats in Tumwater Homes
The Norway rat (Rattus norvegicus) is one of the most damaging rodents in the Pacific Northwest. They stay low to the ground and nest under porches, in crawl spaces, and along foundations. Areas near water attract them, so Tumwater’s streams and wetlands fit them well.
Norway rats dig strong, complex burrows that can lead into homes. Once inside, they chew wood, drywall, and electrical wires. This damage creates safety risks and fire hazards. Look for capsule-shaped droppings, greasy wall marks, and gnawed food boxes in basements or garages.
A small rat problem can grow quickly because they breed year-round. Our team at PCI Pest Control finds nests, seals gaps, and uses family-safe methods to remove rats. We focus on long-term prevention to stop repeat problems.
Roof Rats Around Olympia and Tumwater
Roof rats (Rattus rattus) are slimmer than Norway rats but just as destructive. They climb well and nest in attics, trees, and rafters. In Olympia and Tumwater, they thrive in wooded areas and in homes with overhanging branches or open roof vents.
Also called black rats, they eat fruit, grains, seeds, and pet food. They can get into pantries and garages with ease. Their small, pointy droppings often appear near food.
Since they live up high, you may not notice them until you hear attic noises or find shredded insulation. Roof rat droppings can spread germs on food and surfaces. They can carry salmonellosis, rat-bite fever, and leptospirosis. Urine and droppings can also trigger allergies or make asthma worse. In rare cases, fleas on roof rats can spread murine typhus.
They chew wires, which can start fires. They also damage insulation and stored items. Because they adapt fast and breed quickly, early action helps most.
Deer Mice and House Mice in Washington Homes
Deer mice and house mice are smaller, but they can cause just as much damage. Deer mice are brown with white bellies and long tails, while house mice are gray and slightly smaller.
Both species are extremely common in the Pacific Northwest. Mice and rats can fit through holes as small as a quarter-inch wide, making it easy for them to enter homes through even the tiniest gaps.
Deer mice tend to live in garages, attics, and crawl spaces, especially near wooded areas. House mice, on the other hand, prefer the warmth of indoor spaces like pantries or storage boxes. You might notice shredded paper or insulation, tiny droppings, and faint scratching sounds at night.
Deer mice are known carriers of hantavirus, which spreads through contact with dried feces, urine, or nesting materials. Because of these health risks, professional pest control is the safest way to remove them.
Other Rodents and Wildlife in Tumwater
Not all unwanted visitors are rats or mice. Homeowners in Tumwater and surrounding Thurston County communities often encounter voles, chipmunks, and raccoons. Voles create long surface runways in grass, damaging lawns and gardens. Chipmunks are notorious for stealing seeds from bird feeders and digging under patios.
In wooded neighborhoods, skunks, raccoons, and coyotes often search garbage bins or outdoor pet food for a meal. While these animals typically stay outside, they may cause damage to crawl spaces or siding while searching for shelter. Their activity can also introduce fleas or other parasites to pets.
At PCI Pest Control, we offer full-service wildlife control for Tumwater, Olympia, and Tacoma. Our humane removal methods keep animals safe while protecting your home from further intrusion. Once removed, we provide exclusion work and practical advice to prevent their return.
If you see burrows, chewed siding, or paw prints near your foundation, it’s best to call for an inspection before the damage worsens. Our team can assess whether you’re dealing with small rodents or larger critters and provide the right solution.
Preventing a Rodent Infestation in Your Tumwater Home
Prevention starts with sealing entry points and keeping them sealed, especially in winter.
Check for gaps around vents, pipes, doors, and crawl space doors. Fill holes with steel wool or hardware cloth. Store all food, including pet food, in airtight bins and clean crumbs fast. Keep bird feeders away from the house to avoid spilled seed.
Trim plants and clear clutter in garages and sheds. Move wood, leaves, and debris away from the home. In the attic, look for chewed wires, nests, or damaged insulation. If you see droppings or gnaw marks, call a pro.
At PCI Pest Control, we find weak spots before pests spread. We inspect the attic, crawl space, and exterior. Then we build a custom plan with sealing work and ongoing service through our All Seasons Protection Plans.
