Book a Free InspectionWasps and hornets defend nests aggressively — a small accidental disturbance can trigger swarming and multiple stings. Accurate species ID drives the right approach: dusk knock-down for paper wasps, in-ground injection for yellowjackets, ladder access for hornet aerial nests.
Bright yellow with crisp black bands and a smooth, shiny body. Nests in ground holes, wall voids, and abandoned rodent burrows. The most aggressive wasp in Winnipeg — defends nests with multiple stings. Peak danger August–September.
Big black-and-white wasps that build massive grey football-sized paper nests in trees and tall shrubs. Highly defensive and able to spray venom at threats. Treatment requires ladder access and careful timing.
Long-legged, slender wasps that build open umbrella-shaped paper nests under eaves and deck rails. Less aggressive than yellowjackets but still defensive when threatened. The most common Winnipeg wasp.
Solitary wasps that build tube-shaped mud nests on walls and porches. Long, thin black or metallic-blue body with a thread-thin waist. Rarely sting humans and are often left alone unless near doors.
If you're seeing any of these warning signs, DIY sprays usually trigger defensive stinging without reaching the queen deep inside the nest. Call a licensed Winnipeg wasp exterminator before someone gets stung — especially urgent if anyone in the home has a sting allergy.

Identify the species, locate the nest, and assess access. Aerial nests need ladders, ground nests need direct injection — different species need different tools.
Treat at dusk when wasp activity is at its lowest. Direct application at the nest entrance kills the queen and resident workers. Returning foragers contact the residual treatment over the next 24 hours.
Health Canada–approved products are applied directly into the nest cavity — never sprayed across the yard. Treatment is safe for surrounding plants and nearby pollinators.
Remove the nest after treatment, seal the entry point, and advise on landscaping to discourage re-nesting. Free re-treatment applies if a new nest appears in the same spot.
Winnipeg's short summer pushes wasp queens to build nests fast — paper wasp queens emerge in May and start construction by mid-June; yellowjacket populations explode through July and August. By September a single nest can hold 5,000+ workers ready to defend at any disturbance.
Bald-faced hornets build grey football-sized paper nests up to 60 cm wide in trees and tall shrubs across River Heights, Wolseley, and St. Vital. Mud daubers prefer sheltered porch overhangs and garage walls across the city — far less aggressive but worth removing if near doorways.
FAQ

Pricing is affordable and based on inspection findings, pest activity, access, and treatment scope. We confirm the recommendation before work begins.
Yes. Terra13 runs a 24/7 emergency line for active wasp and hornet situations — aggressive nests near doorways, someone with a sting allergy at risk, or kids and pets in the yard. Same-day response is available for most Winnipeg addresses inside the perimeter.
A standard paper wasp or mud dauber treatment takes 15–30 minutes on-site. Ground yellowjacket nests usually take 30–45 minutes with a verification visit at 48 hours. Large bald-faced hornet aerial nests require ladder work and run 45–90 minutes.
Yes. Treatments are applied directly at the nest entrance at dusk when wasps are calm and inside the nest — never sprayed across open yards or flower beds. Re-entry to treated areas is typically 30 minutes once treatment dries.
No. Wasp removal doesn't require evacuation. We'll ask you to stay inside with windows closed during the treatment window, and to keep pets indoors for an hour afterward to avoid contact with stunned wasps falling near the nest.
Free re-treatment applies within the warranty period — typically 30 days for paper wasps and mud daubers, 60 days for yellowjacket and hornet nests. If a new nest appears in the exact same spot within warranty, we come back at no cost.
Yes — wasps and hornets are pollinators and eat huge numbers of garden pests, so they are ecologically valuable. We only treat nests when they pose a direct risk to people, pets, or property access. We'll tell you straight up if leaving a distant nest alone until fall is the right call.
Free inspection, affordable inspection-based quote, and a satisfaction guarantee. Especially urgent if anyone in the home has a sting allergy. Call our 24/7 line or send photos and we'll triage the species before we arrive.
