Wasps

– Watch for umbrella shaped paper nests under eaves.
– See wasps flying fast around doors and patios.
– Hear a steady buzz near decks in summer evening.
– Find chewed wood fibers at nest attachment points.

Direct aerosol wasp freeze applied at night; nest removal after confirmed colony knockdown; residual treatment of attachment site to deter rebuilding at same location.

We treat nests at night with a fast spray. Then we remove the nest and clean the site.

– Inspect eaves, door frames, and window casings each spring for early nest construction.

– Apply residual repellent to common nest sites (eaves, shutters) before paper wasp season.

– Seal gaps in eaves and soffits to reduce protected attachment sites.

– Wear protective clothing and approach nests only at night when wasps are inactive.

– Remove and dispose of knocked-down nests promptly to discourage recolonization.

– Inspect eaves and vents each spring for new nests.

– Seal gaps in soffits and under porch beams.

– Keep trash cans closed near picnic spots and parks.

– Avoid sweet drinks outside during Boise River outings.

Open, umbrella-shaped paper nests suspended from eaves, door frames, windowsills, and tree branches; nests are small (20–75 cells) and visible; colonies peak midsummer and die off by first frost.

Wasps show up on Boise porches and eaves. They often nest under eaves and window frames.
