Wasp & Hornet Control in North Idaho & Eastern Washington

A nest above the door, yellowjackets in the lawn, or steady flights into a wall? Supernova identifies the insect, assesses the nest and access, and explains the treatment. Get local help with wasps around your home—without a long-term contract.

Start with the insect and its nest

Closeup of a wasp

Paper wasps, yellowjackets, and bald-faced hornets call for different approaches depending on where they are nesting. Color alone is not enough to identify them.

If you can photograph the insect or nest from a safe distance, send us the picture. Tell us whether the nest is exposed, in the ground, or hidden behind part of the building. Do not approach a nest to get a better photo.

Paper wasps

Usually slender, with long legs and an open paper comb visible from below. Eaves and other sheltered ledges are common nest sites. Even a small nest matters when it is beside a doorway or play area.

Yellowjackets

Often compact, with black-and-yellow markings. Depending on the species, nests may be underground, in a building cavity, or above ground. Steady traffic through one opening is a useful nesting clue.

Bald-faced hornets

Mostly black with pale face and body markings. They build enclosed paper nests above ground, often in trees or on structures. They are a type of aerial yellowjacket and can defend their nest vigorously.

Could they be bees?

Honey bees and bumble bees often look hairier than wasps. Have the insect identified before treatment. A honey-bee swarm or colony may be a situation for an experienced beekeeper; do not assume every flying stinger needs the same service.

Found a nest? Start here.

Keep people and pets away from the activity. Tell us if the nest is near an entrance, walkway, play area, or a place you cannot easily avoid. Mention any known sting allergy when arranging the visit.

  • Exposed nest: Share its approximate height and what it is attached to. Avoid knocking it down or reaching it from a ladder.
  • Ground entrance: Point out the location from a distance and keep mowing or yard work away from it.
  • Wall or roofline opening: Leave the entrance open until the nest has been assessed and controlled. Blocking an active entrance can redirect wasps into the home.

Late-summer activity or a winter visitor?

Yellowjackets can become more noticeable around outdoor meals and garbage as the season progresses. An insect visiting your food is not proof that its nest is on your property.

In colder months, an occasional wasp indoors may be a queen that sheltered in the building. That is different from regular flights at an active colony. Repeated indoor sightings deserve identification and a closer look.

Our fall pest and overwintering guide explains seasonal visitors, sealing, and what to do when they appear inside.

A severe reaction after a sting is a medical emergency. Call 911 for trouble breathing, tongue or throat swelling, or fainting after a sting. If prescribed emergency epinephrine is available, use it as directed while help is on the way.

Reduce the things that attract wasps

  • Keep outdoor food and drinks covered, including pet food.
  • Close trash lids and clean up spills and fallen ripe fruit.
  • Repair damaged screens and weatherstripping. Coordinate repairs around a suspected nest with us first.
  • Note recurring activity around eaves, sheds, play equipment, or outdoor living areas so we can inspect those spots.

Wasps also prey on other insects. A nest well away from people may be left alone when it can safely be avoided. We can help you decide whether treatment is useful for your situation.

How Supernova handles a wasp problem

Identify and assess. We review the activity, locate the nest where possible, and consider height, access, nearby people, and the surface or cavity involved. Tell us about earlier sprays or attempts to block the opening.

Treat the source. We select the application method for the insect and nest location. Exposed nests, ground nests, and hidden colonies are not interchangeable jobs. Product choice and placement follow the label.

Remove accessible nests where appropriate. We explain what can be reached and removed, and whether a hidden nest needs a different approach. Physical removal from inside a wall may require additional access or repair work; we discuss the scope before proceeding.

Explain the next steps. We tell you which areas to avoid, when they can be used again, and what activity to report. Residual treatment may help manage returning wasps where appropriate, but it does not guarantee that no new wasp or nest will appear.

For docks, boathouses, and other locations near water, tell us exactly where the nest is. Access and the product’s permitted use determine what we can do there. Our preparation and aftercare guide covers general household precautions.

Help with one nest or recurring activity

Supernova Strike offers a one-time service option. We assess the nest and explain treatment, removal access, price, and any recommended follow-up before you decide.

For ongoing pest pressure, Supernova Shield provides regular visits every 90 days. Active quarterly customers receive free re-service between scheduled visits for covered pest activity. Report a new nest when you notice it rather than waiting for the next visit.

Nova Naturals is our botanical program, typically scheduled about every four weeks. Ask us whether it fits the nest and location; botanical products still require precautions.

Call (208) 413-8027 for current availability. Same-day service may be possible, especially if you call earlier in the day; we confirm timing for your location.

Local wasp control across our service area

We serve North Idaho, including Coeur d’Alene, Post Falls, Rathdrum, and Hayden; the Palouse, including Moscow and Pullman; and the LC Valley, including Lewiston, Clarkston, and Asotin.

When you contact us, include your town, the nest’s location and approximate height, and whether wasps are getting indoors. Those details help us plan the visit.

Wasp and hornet control questions

Do you always remove the whole nest?

Accessible exposed nests can often be removed as part of the work. A colony inside a wall or underground can require a different approach. We explain the treatment and removal scope after assessing access.

Can I seal the hole where wasps enter?

Not while it is serving an active nest. Blocking that route can send wasps toward another exit, including indoors. Have the nest assessed and controlled first, then coordinate the repair.

Will treatment stop every wasp from returning?

No. We focus on the nest and activity identified at your home. Foragers from elsewhere or a new nest can create later activity. Contact us if traffic continues at the treated entrance or a new problem appears.

Do yellowjacket traps solve a nest problem?

Traps can reduce some foraging yellowjackets, but they do not reliably eliminate an established nest and do not attract every wasp species. A trap catching insects is not proof that a hidden colony is gone.

Is treatment appropriate around children and pets?

Tell us about the areas your family and pets use. Keep them away during service and follow the return instructions for the actual products and location. A general “safe once dry” rule does not cover every treatment.

Does a wasp indoors in winter mean an active nest?

Not necessarily. A sheltered queen can become active indoors without a colony being present. Repeated sightings or steady traffic through one opening need a closer look. See our fall pest and overwintering guide.

Tell us where the wasps are nesting.

Share the location and activity you can observe safely. We will help you understand the next step and confirm availability.
