Ant Control in Lake Stevens Starts With Which Ant

Carpenter ants are large, a quarter inch or more, usually black, and busiest at night. They do not eat wood; they hollow it out to nest, and the sign is fine sawdust, called frass, under a window, a baseboard or a deck board.

Sugar and odorous house ants are tiny and trail toward food. Spraying them can split the colony and make it worse, so they get bait instead. If you are not sure which you have, carpenter ants vs. sugar ants walks through the differences.

Where Carpenter Ants Nest Around Lake Stevens

Carpenter ants need wood that stays damp. In a town built around a lake and surrounded by woods, there is plenty of it.

Decks, Docks and Boathouses

Wood that sits over or near the water stays damp for months. Deck ledgers, rim joists under a lake-facing deck, dock framing and boathouse sills are where we look first on a lakefront lot.

Decades of wet winters soaking into window framing, sill plates and old siding leave softened wood, which is what carpenter ants hollow out. A leak that was fixed years ago can still be the spot.

Wooded Lots and Old Stumps

Many lots in Lake Stevens back onto second-growth woods, and stumps, buried roots and woodpiles make good outdoor nests. The parent colony often lives out there and sends workers into the house.

Carpenter Ants Inside in Winter Mean the Nest Is Inside

Outdoor colonies go quiet in the cold. So when big black ants are walking across the kitchen floor in February or early March, the colony is almost always living in the house: a wall void, the framing around a window, or the subfloor under a bathroom.

That is the most useful time to call, because the ants lead us right to it. Spraying the ones you can see does nothing to the nest. If a crawl space with a failed vapor barrier is what kept the wood damp, we can fix that too with crawl space cleaning in Lake Stevens.

How We Get Rid of Ants for Good

  1. 01

    Identify the ant

    Carpenter ants and sugar ants need opposite treatments, so we confirm which one you have before anything is applied.

  2. 02

    Follow the trail

    Carpenter ants keep satellite nests away from the main colony. We follow the trails back to find the parent nest and the satellites.

  3. 03

    Treat the nests

    We treat the parent nest and every satellite we can trace. Sugar and odorous house ants get bait they carry back to the colony, not a spray that scatters it.

  4. 04

    Point out the moisture

    Dry wood is not somewhere carpenter ants can nest. We show you the damp spot that drew them, so it gets fixed and the colony does not move back in.

Questions, answered

Lake Stevens Ant Control Questions

I See Big Black Ants Inside in Winter. Is That Bad?

It is worth a call. Outdoor colonies are inactive in the cold, so carpenter ants walking around inside in late winter or very early spring usually mean the nest is inside the house, in a wall void, a window frame or the framing under a bathroom. That is the nest we want to find.

Is It Carpenter Ants or Sugar Ants?

Carpenter ants are big, a quarter inch or more, usually black, and most active at night near damp wood. Sugar and odorous house ants are tiny and trail along counters toward food. We confirm the species on the first visit, because the treatment for each is completely different.

Do Lakefront Homes Get More Carpenter Ants?

They have more wood that stays wet: docks, boathouses and the framing under lake-facing decks. That gives carpenter ants more places to nest close to the house, so we spend more of the inspection below the deck and along the water side.

What Does Ant Control in Lake Stevens Cost?

It depends on the species, the size of the colony and whether the nest is in a wall or out in the yard, so we quote after a look rather than over the phone. A one-time carpenter ant treatment is priced differently than an ongoing program. You have the number before we start.

Are Your Ant Treatments Safe for Kids and Pets?

Yes. We use products rated for occupied homes and apply them to trails, entry points and nests rather than across living space, and we walk you through every product and where it goes before we treat.
