Wasp Removal in Vancouver, BC

Wasp and hornet activity peaks between July and September, when colonies reach their maximum size. A nest that seems manageable in June can become a serious hazard by August.

Pricing depends on the nest location, accessibility, and treatment required. When possible, customers can send our office a photo and description of where the activity is located so we can determine the appropriate service, pricing, and availability.

Along with wasps, Vancouver homes commonly deal with rodents, ants, and cockroaches. See our full Vancouver pest control page for details.

The four species we most commonly treat in Metro Vancouver are Yellow Jackets (Vespula species) — the most aggressive, often nesting underground or in wall voids; Bald-Faced Hornets (Dolichovespula maculata) — large grey papery nests in trees or under rooflines, very defensive; Paper Wasps (Polistes species) — smaller open-comb nests under eaves and railings, moderate aggression; and Mud Daubers (Sceliphron species) — solitary, tube-shaped mud nests on walls and ceilings, low aggression. Each species requires a different treatment approach, which is why identification always happens before we treat.

Wasps do not reuse old nests — every spring, new queens scout for suitable nesting locations and build fresh nests from scratch. However, the same spots that were attractive once (eave gaps, wall voids, dense shrubs, ground burrows) will be scouted again the following season. As part of every job, we provide a written prevention report that identifies and documents these vulnerable areas so you can seal them before the next season begins.

In most cases, yes. Once the colony is fully eliminated, we remove and safely dispose of accessible nests as part of the service. For nests located inside wall voids, underground, or in enclosed structural spaces, physical removal may not be possible without causing damage — but the colony will be fully treated and eliminated. Leaving a treated nest in place does not attract new wasps, as each season new queens build entirely new nests.

Yes. Ridall uses Health Canada–registered treatments applied directly to the nest rather than broadcast-sprayed across your property. We follow all provincial pesticide application regulations. After treatment, we advise a short re-entry interval — typically 1–2 hours — before children and pets return to the treated area. Your technician will give you specific guidance based on the products used and the nest location.

Most residential treatments take 30–60 minutes on-site. For accessible nests under eaves or in trees, you’ll typically see full results within 24–48 hours as the colony dies off. Underground nests or nests inside wall voids may require a follow-up visit 7–10 days later to confirm full elimination. Your technician will advise on expected timelines based on species and nest location at the time of inspection.

DIY removal carries serious risk and is strongly discouraged. Yellow jackets and bald-faced hornets are highly aggressive when disturbed and can sting multiple times without losing their stinger. A mature nest can contain thousands of wasps. Without professional protective equipment, the correct treatment products, and knowledge of nest type and location, disturbing a nest often triggers a mass defensive response. This is especially dangerous for anyone with a known venom allergy.

The most common signs are wasps flying repeatedly in and out of a fixed location — under eaves, into a wall gap, or into a ground hole. You may also notice a visible grey or brown papery nest structure in trees, shrubs, or under rooflines. Audible buzzing from inside a wall cavity without a visible exterior nest is a key sign of yellow jackets nesting in a wall void. If you’re seeing increased wasp activity near food, garbage, or compost bins, a colony is likely nearby.
