Are you looking for mosquito treatment this winter so you can plan ahead for a pest-free spring with our expert, family-friendly solutions?

About us
We understand that mosquitoes can turn your outdoor spaces from relaxing retreats into no-go zones. At PCI Pest Control, we’ve developed a comprehensive mosquito treatment program that targets these pests at every stage of their lifecycle.
Our approach combines biological breeding-site stations with barrier treatments to deliver results that last. We don’t just spray and leave. We identify standing water sources, treat breeding areas with slow-release larvicides, and apply EPA-registered adulticides to vegetation and harborage zones where adult mosquitoes rest.
What sets us apart is our commitment to ongoing protection through monthly service visits from March through November. During each visit, we refresh breeding-site stations, re-treat standing water, and reapply barrier treatments to keep your property protected throughout mosquito season.
We offer flexible service tiers to match your needs and budget. Our Standard Plan focuses on breeding-site maintenance and standing water treatment, while our Plus Plan includes fresh barrier spray at every visit with complimentary callbacks for high activity periods.
Every treatment we perform is family and pet-friendly once dried, typically within 60 minutes. Our barrier sprays bond to foliage and remain effective even after moderate rainfall, giving you consistent protection between visits.
Whether you need season-long mosquito control or a one-time treatment before an outdoor event, we have the expertise and technology to help you reclaim your yard.

Our Process
Our Process: Protecting Your Yard From Mosquitoes
01
We begin with a detailed exterior inspection of your property to identify mosquito breeding sites and resting areas. For example, we check for standing water in gutters, flower pots, bird baths, and low-lying areas where fall rains create ideal breeding conditions.
During this first visit, we place one or more biological breeding-site stations that release slow-acting larvicide to sterilize mosquito larvae before they mature. We also treat any standing water that cannot be drained and apply a low-volume barrier mist to vegetation, shaded zones, and under decks where adult mosquitoes rest during cooler fall temperatures.
02
During the second visit, we service and refresh all biological breeding-site stations to ensure continuous larvicide release throughout the property. In November, as temperatures drop and mosquito activity slows in the Pacific Northwest, we focus on treating any remaining standing water from fall rains and reapplying barrier treatment to vegetation and shaded resting areas where cold-weather mosquitoes seek shelter.
For customers on our Plus Plan, we deliver a fresh barrier spray at every monthly visit to maintain protection against late-season mosquito activity. We also inspect for new breeding sites that may have developed since the initial treatment, such as clogged gutters or low-lying areas that collect water during November’s frequent rainfall.
03
During the third visit, we conduct a final inspection to verify that all breeding sites remain controlled and barrier protection stays effective through the end of mosquito season. As November transitions into December and overnight temperatures in the Pacific Northwest drop below the threshold for mosquito activity, we remove or winterize biological stations, treat any final pockets of standing water from late-fall storms, and apply a closing barrier treatment to vegetation where overwintering mosquito eggs may be present.
For Plus Plan customers, we deliver one last comprehensive barrier spray to ensure protection extends through any unexpected warm spells that can trigger late-season hatching. We also provide recommendations for winter property maintenance, such as clearing gutters and addressing drainage issues before spring rains return, so your property stays prepared when mosquito season resumes in March.
