Seattle Pest Control | WA’s Premier Pest Pros


When people think of Washington State, Seattle is often the first thing to come to mind. The Emerald City is home to some of the largest companies in the country, including Amazon, Starbucks, and Boeing. Add to that a short drive from tech giant Microsoft and a bustling downtown area and it is easy to see why Seattle has often been voted as the best city in the United States for business!

There’s more to Seattle than its thriving business sector, however. From the countless shops and restaurants of Pike’s Place Market to MoPOP, the Pacific Science Center, and the Space Needle, there are countless things to see and do in Seattle. Take in a concert at Benaroya Hall or check out one of the countless conventions at the Washington Convention Center.

If you’re a sports fan, Seattle also has you covered with the Seahawks, Mariners, and Sounders. Seattle also features a wide array of parks and beaches, including the Alki Beach and Gas Works Park. There really is no city quite like Seattle!


Despite significant urban development, Seattle still has many greenbelt areas that serve as home to a wide variety of pests. Seattle’s unique combination of man-made and natural conditions invites infestation from numerous types of insects, including several species of ant.

The two most common types of ant seen in the Seattle area are odorous house ants and carpenter ants. More commonly known as sugar ants, odorous house ants are more of a nuisance than anything else, commonly found in kitchens eating your food. Carpenter ants, on the other hand, can be extremely destructive and cause major structural damage to homes and office buildings.

Rats and mice thrive in major metropolitan areas, so naturally one of the most common pests we see in Seattle are rodents. The large concentration of different restaurants and people in conjunction with pockets of greenery and water make for the perfect conditions for rodents.

This is especially true for cities located near large bodies of water like the Puget Sound; rodents tend to make their way into homes and take refuge in attics and crawl spaces. While not necessarily aggressive, rodents can pose major health and contamination risks.

Establishing effective prevention methods for rodent infestations can be time-consuming; it requires a thorough inspection, repair of any rodent entry points, mechanical trap installation, and bait station placement. Exclusion is part of the solution!


Treating an ant infestation is a fairly complicated process. Our ant treatment involves a significant amount of detective work, specialized interior baiting, and liquid chemical treatments, as well as an exterior chemical application to the home or building and various areas on the property.


Bed bugs are often found in or around beds and bedrooms. They are notoriously difficult to locate due to their skill at hiding, and made even more challenging by their fast maturity rate and longer life span. Identifying the origin and scope of an infestation requires more detailed inquiry.


The most common species of termites in Washington are the Pacific Dampwood and Western Subterranean termite. Termites can do significant structural damage to a home or business, and require extensive preventative treatment to be fully eliminated and excluded.


There are several different species of stinging insects native to the Pacific Northwest. Many are non-aggressive and serve a vital ecological function; however, some species—particularly yellow jackets, wasps, and hornets—can be extremely aggressive and require removal.


There are various species of spiders found throughout Washington and the Puget Sound region. While spiders in general can be beneficial in the elimination of other pests, they are not usually welcome visitors in our homes and their bites should be avoided.
