Common Pests In Seattle, WA

Carpenter Ant Control In Seattle

Carpenter ants are one of the most important pest concerns for Seattle homeowners. Unlike termites, carpenter ants do not eat wood. Instead, they excavate galleries inside damp or damaged wood to create nesting areas.

Seattle’s moisture makes homes especially vulnerable to carpenter ant activity. Leaky roofs, damp crawl spaces, aging deck posts, wood near soil, and poorly ventilated areas can all attract these pests. Signs of carpenter ants may include large black ants, sawdust-like frass, rustling sounds inside walls, or ants trailing near windowsills and foundations.

EnviroGuard provides carpenter ant inspections and targeted treatments designed to locate activity, address nesting areas, and help reduce the moisture conditions that make infestations more likely.

Rodent Control In Seattle

Rats and mice are a major concern in Seattle, especially during the rainy fall and winter months when they look for shelter indoors. Norway rats are common in the city and often travel near sewer lines, compost bins, garbage areas, and dense vegetation. Roof rats may also be found in neighborhoods with mature trees and heavy canopy cover.

Rodents can enter through small openings around vents, doors, utility lines, crawl spaces, rooflines, and foundation gaps. Once inside, they can contaminate food, damage insulation, chew wiring, and create health concerns.

EnviroGuard’s rodent control services include inspection, trapping or removal where needed, and recommendations for sealing entry points to help prevent rodents from getting back inside.

Spider Control In Seattle

Seattle is home to several spider species, including the giant house spider. While many spiders are harmless and even help reduce other insects, they can still become a nuisance when they appear in bathrooms, basements, garages, storage areas, and living spaces.

Spider activity often increases when other insects are present. Our spider control services focus on reducing spider activity, treating problem areas, removing webs where appropriate, and helping address the insects that may be attracting spiders to your property.

Silverfish Control In Seattle

Silverfish thrive in humid environments, making Seattle homes a natural fit for these moisture-loving pests. They are often found in bathrooms, basements, closets, laundry rooms, storage boxes, and other damp or quiet spaces.

Silverfish do not bite, but they can damage books, paper, wallpaper, stored clothing, and other starchy materials. Reducing humidity, improving ventilation, and treating active areas can help control silverfish problems.

EnviroGuard can help identify where silverfish are living and recommend steps to reduce moisture and pest activity inside your home.

Ant Control In Seattle

In addition to carpenter ants, Seattle homes may experience problems with nuisance ants that enter kitchens, bathrooms, and other indoor areas in search of food and water. Ant trails often appear when colonies find access to crumbs, sugar, moisture, or pet food.

Successful ant control starts with identifying the species and understanding where the colony is active. EnviroGuard uses targeted ant control treatments to address activity at the source and help reduce future infestations.

Moisture-Related Pest Control In Seattle

Many pest problems in Seattle are connected to moisture. Crawl space humidity, clogged gutters, poor drainage, leaky plumbing, damp wood, and vegetation touching the home can all create pest-friendly conditions.

Our team looks for these underlying issues during inspection and provides practical recommendations to help make your property less attractive to pests. By addressing both the pests and the conditions that support them, we help create longer-lasting protection.
