Mosquito Control in Portland, OR
Mosquito Control in Portland, OR
Portland's reputation for rain is exactly what makes mosquito control here so important. West Nile virus has been detected in mosquitoes across Multnomah, Washington, and Clackamas counties in recent years, and species like the western encephalitis mosquito thrive in the standing water left behind by our frequent showers. Yards in areas like Beaverton, Gresham, Lake Oswego, and inner Portland all face the same challenge: moisture, shade, and lush vegetation that mosquitoes love.
We serve homeowners across the metro area with treatments designed for Oregon's climate — timed around the spring emergence and the long breeding season our mild summers extend. Whether you're near the Willamette's riverbanks, the wetlands of Sauvie Island, or just a typical leafy Irvington lot, we'll help you take your outdoor space back. Get your free quote today and enjoy a mosquito-free Portland summer.
Portland's rainy springs and lush greenery create ideal breeding conditions for mosquitoes. From May through September, standing water in gutters, planters, and the shaded corners of typical Pacific Northwest yards can produce wave after wave of biting mosquitoes — turning your patio or garden into a place you avoid instead of enjoy.
Our licensed technicians provide targeted mosquito control throughout Portland's neighborhoods, reducing populations at the source and protecting your outdoor space all season long with treatments tailored to our region's unique climate.

Our Mosquito Control Process
- Property Inspection We walk your Portland yard to locate mosquito resting and breeding sites — standing water, dense shade, clogged gutters, and drainage problem areas.
- Custom Treatment Plan Based on our findings and your yard's layout, we build a plan targeting larvae in water sources and adults in vegetation where they hide.
- Targeted Application Our technician treats shrubs, tall grass, fence lines, and other harborages with precision equipment, focusing on the areas mosquitoes actually use.
- Ongoing Protection Monthly visits from spring through September maintain the barrier, since our wet climate continually produces new broods throughout the season.
