Olympia Pest Control | WA’s Premier Pest Pros


Incorporated as a city in 1882, Olympia has been the capital of Washington State since 1853 and currently serves as the county seat for Thurston County. It sits at the southern tip of Puget Sound on Budd Inlet, serving as a major port city for the area. Olympia’s port city status, five miles of Puget Sound waterfront, aged infrastructure, numerous parks and nature conservatories, and homelessness epidemic create an environment heavy with conducive conditions for pest problems.

Our state’s capital is packed with public parks and nature conservation areas like Woodard Bay for us to enjoy. Many pests call these natural areas home, including carpenter ants, termites, and spiders. We certainly don’t want these insects gone altogether, but we do want to do our part in protecting the health and safety of our neighbors.


The aged infrastructure in Olympia may be one of the biggest contributors to the many pest problems that we see. The older historical buildings, structures, and homes from the late 1800s can be really neat to look at, but often come with hidden pest issues like termites, ants, and rodents.

Olympia’s close proximity to the water—especially the port—creates challenges for the pest professional. Our technicians regularly battle rodent infestations in and around the communities near the water. Rats and mice are everywhere here in the Pacific Northwest, but nowhere more than in port cities like Olympia. Poor sanitation will always be coupled with pests. Rodent populations can explode and bed bugs spread like wildfire in some of the conducive conditions throughout our city.


We’ll call you back, and schedule the best time for you!


Our experienced technicians work daily to ensure that populations of rats, mice, and bed bugs maintain manageable levels. Sentinel Pest Control can provide you with comprehensive protection from any pest you may encounter. Let our team be part of your solution!


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.
