Mosquito control

Mosquito control for yards across Snohomish and King County.

We treat yards for mosquitoes across Lake Stevens, Snohomish, Monroe, Woodinville, and the wetter low-lying parts of Snohomish and King County. Real mosquito control does two things at once: it knocks down the adults you feel and eliminates the standing water they breed in. Doing only one never holds. Anywhere near the Snohomish wetlands or the river valleys gets heavy pressure from May through September, so we treat the source and the resting spots together.

Mosquitoes at a glance

What you need to know about mosquito control.

Mosquito control that actually works starts with the standing water in your yard, not the fog. A backyard fogger kills the adults for about a day, then the breeding source refills them by the weekend. We find and treat every standing-water source, larvicide the water we can't drain, and barrier-treat the shaded spots where adult mosquitoes rest, which keeps the population down for weeks at a time.

What we treat

What you're
actually dealing with.

Identification matters more than treatment. The same product on the wrong species can scatter a colony and double the problem. Here is what we typically find on calls in the Lake Stevens, Lynnwood, and Edmonds area.

What to watch for

Signs you have
a real problem.

One sighting isn't always a problem, but a few of these together usually means it's time. We're happy to take a look and tell you what's going on.

  • 01

    Persistent biting in your yard, especially at dusk

  • 02

    Standing water in gutters, low spots, or untouched buckets

  • 03

    Larvae visible in birdbaths, pet bowls, or planter saucers

  • 04

    Heavy mosquito activity along shaded fence lines and under decks

  • 05

    Bites on legs and ankles after walking through the lawn

How we work

Our process
for mosquitoes.

Every visit runs the same way: a real walk-through, a written report after every service, and warranty re-treatment at no charge, within 48 hours, if the pests come back between visits.

01

Identify breeding sources

We walk the property and find every standing-water source: gutters, planter saucers, low spots in the yard, neglected birdbaths, drainage pinch points. Drain or treat each one.

02

Larvicide where we cannot drain

Some water cannot be removed (rain barrels, ponds, low spots in clay soil). We apply targeted larvicide that kills mosquito larvae without harming the pond ecosystem.

03

Barrier treat the resting spots

Adult mosquitoes rest on the underside of leaves, on shaded foliage, and under decks. Eco-friendly barrier treatment in those spots reduces the adult population for weeks at a time.

Why call us instead of DIY

A backyard fogger that only treats adults gives you about 12 hours of relief. The mosquitoes you fogged are replaced from the breeding source the same week. Real mosquito control eliminates the source, then keeps the adult population suppressed with seasonal treatments.

How does a mosquito yard treatment work?

We treat the shaded resting spots where adult mosquitoes wait out the day, like dense shrubs, tree lines, and under decks, and we knock down standing-water breeding sites. It is a backyard treatment calibrated to the season, heavier from May through August.

How much does mosquito control cost?

Mosquito control is a seasonal program rather than a single visit, since the treatments hold for a few weeks and then need a refresh. Price depends on the size of the yard and how much standing water it has. We walk the property and give you a seasonal number upfront, before any work starts.

Does mosquito spraying actually work?

Spraying the adults works, but only for a day or two if that is all you do, because the breeding source keeps producing more. The treatments that hold combine barrier spraying of the resting areas with larviciding or draining the standing water. That is the difference between a fogger and real mosquito control.

How long does a mosquito treatment last?

A treatment typically holds for several weeks, which is why most yards are on a recurring schedule through the warm months. Heavy rain and fast growth can shorten that, so we time visits to the season and your property.

When should I start mosquito control in the PNW?

Late spring is the time to start, before the population builds. Getting ahead of the first hatch makes the whole season easier than trying to knock down a heavy population in July.

Is mosquito treatment safe for pets and pollinators?

We use products rated for occupied yards and apply them to resting areas rather than blooming plants where pollinators feed. We will walk you through timing so kids, pets, and bees stay clear of fresh treatment.
