Why a wasp nest becomes dangerous
A colony can reach several hundred individuals by late summer. Wasps defend the nest as a group and can sting multiple times. For an allergic person, a single sting can be a medical emergency.
Mistakes not to make
- Spraying the nest yourself in broad daylight: the whole colony attacks.
- Using water, fire or blocking the entrance: dangerous and ineffective.
- Hitting or shaking the nest.
- Approaching without a clear escape route.
What you can do while waiting
Keep your distance, close nearby windows, keep children and pets away from the area, identify (from afar) the exact location and activity, and avoid perfumes and bright colours nearby. Note if anyone in the household is allergic: flag it as a priority.
Why call a professional
A technician intervenes with protective equipment, at the right time (early or late, low activity), treats the nest at the source and removes it — including high-up nests or those in a wall cavity, unreachable without risk. Fast response, often the same day in season.

Frequently asked questions
Is a wasp sting dangerous?
For most people, painful but not serious. For an allergic person, a sting can cause anaphylactic shock: it's an emergency. Multiple stings are dangerous for everyone.
Can I remove a nest myself?
Strongly discouraged, especially high up, in a wall or if the nest is large. The risk of multiple stings is high and some reactions are serious. A pro has the equipment and method.
How much does wasp nest removal cost?
From about $99 depending on location and nest size (a nest in a wall cavity takes more work). Clear quote before the job.
Do you respond quickly?
Yes, often the same day in high season (July to September) across the Greater Montreal area, 7 days a week.
