Wasps & Hornets on the Olympic Peninsula

The only pest on this list with a genuine safety dimension. Nest removal is included in the contract.

Active: Nests build from May, peak late July through September Covered by our contract
Identification

How to Tell What You Have

Nest shape tells you more than the insect does. An enclosed grey football hanging in the open is bald-faced hornet. A small open honeycomb under an eave is paper wasp. Steady traffic in and out of a hole in the ground or a gap in siding is yellowjacket, and that is the one to treat carefully. Honey bees are protected and beneficial — a dense cluster of golden-brown bees is a swarm and should go to a beekeeper, not a pest company.

Species

What Lives Here

Bald-faced hornet

Black and white, builds the large grey paper nest hanging from a branch or eave. Highly defensive within about 10 feet of the nest.

Yellowjacket

Yellow and black, often nests in the ground or inside wall voids. The aggressive one at your picnic in August. Ground nests are easy to strike accidentally with a mower.

Paper wasp

Slimmer, long dangling legs in flight, builds the small open umbrella-shaped comb under eaves and rails. Comparatively docile.

Mud dauber

Builds small mud tubes on walls. Solitary and essentially harmless — usually best left alone.

Local Conditions

Wasps & Hornets in Our Service Area

South-facing walls and slopes take the most nesting activity because they stay warm through the afternoon — Bell Hill and Sunland in Sequim are textbook. Barns, pole buildings, and high eaves in Chimacum and Carlsborg give protected nesting with little disturbance. Ground-nesting yellowjackets are the real risk on pasture-adjacent property, where a mower or a footstep can open a nest without warning.

What draws them in

Straight Answer

Does Spraying Actually Work for Wasps & Hornets?

Yes — the contract handles this. Perimeter treatment is the right tool for this pest, and it is covered at no extra charge.

Nest removal is included in the contract, and scheduled visits catch nests while they are still small — which is the whole point. A nest treated in June is a two-minute job; the same nest in September holds thousands of insects and is genuinely hazardous. That is also why we do not recommend homeowners handle wall-void or ground nests themselves.

What you can do yourself, free

Call us when: A nest is inside a wall void, in the ground where people walk, larger than a fist, or anywhere near someone with a sting allergy. Do not attempt those.

What attracts wasps & hornets to a property?

Protected overhangs, eaves, deck rails, and open outbuildings. Uncovered rubbish, compost, fallen fruit, and outdoor pet food. Sugary drinks and meat outdoors in late summer. Existing gaps into wall voids and soffits. Abandoned rodent burrows, which yellowjackets readily colonise.
