Eco-friendly and professional solutions against wasps and hornets
Wasps and hornets pose an immediate danger to your safety and that of your loved ones.
Their sting is painful, sometimes allergenic, and their nest can house hundreds of individuals ready to defend their colony.
At Extermi Pro, our certified technicians intervene 24/7 to eliminate wasp and hornet nests in Montreal, Laval and on the South Shore.
We use products approved by Health Canada and safe and ecological methods adapted to each situation.
Extermi Pro destroys wasp and hornet nests in Montreal, Laval, the North Shore and the South Shore by applying a Health Canada-approved professional insecticide directly to the nest, backed by a written guarantee. The service covers locating the nest and identifying the species, removing the destroyed nest, preventive treatment and post-treatment follow-up. Do you need to leave home? Not always: it depends on the treatment and the areas involved. The technician gives you safety instructions (ventilation, areas to avoid) and chooses a method suited to homes with children and pets.
✅ Rapid response — ✅ Certified products — ✅ Written warranty
Why act quickly against a wasp nest
A wasp nest can develop in just a few days, reaching hundreds of insects.
If you wait, you risk:
Multiple stings or a group attack
Rapid spread to other areas of the house
Property damage (plaster, insulation, woodwork)
The dangers of hidden nests
Found in eaves, hollow walls, fences, or attics
Often invisible until they become dangerous
Can cause long-lasting infestation if left untreated
Emergency response
On-site within 24 hours for any active nest
Complete inspection + targeted treatment around the area
Use of professional safety equipment
Preventive treatment to avoid reinfestation
Wasps, hornets, bumblebees: which one is threatening you?
Not all flying insects pose the same risk.
Here's how to tell them apart 👇
Wasps
Very aggressive in summer
Papier-mâché nests (roofs, walls, shrubs)
Can sting multiple times
Very dangerous near homes
Hornets
Larger and noisier than wasps
Very territorial, attack in groups
The European hornet nests in tree trunks or roofs.
The Asian hornet is an invasive species: any sighting should be reported.
Bumblebees
Not very aggressive, useful for pollination
Can become a nuisance if they nest in a facade or shed
Professional relocation recommended to preserve their ecological role
Bees
Insects essential for pollination and ecological balance
Generally non-aggressive, except when defending their hive
Have a single stinger: they die after stinging
If a colony settles in a wall or tree, a professional beekeeper must intervene to ensure safe removal.
Wasp nest season in Montreal
Wasp nests are most active from July to September in Montreal. 👉 The earlier a nest is treated, the simpler the job.
Attempting to destroy a nest yourself is dangerous:
Wasps react violently to vibrations and heat.
Consumer products are not very effective.
Improper handling can trigger a group attack.
Our teams wear full protective suits and use telescopic poles and pressurized sprayers to safely remove the nest.

Frequently asked questions
It is recommended to call as soon as signs of infestation are observed: noises in the walls, droppings, visible nests, constant comings and goings of wasps or flying insects. Early intervention keeps the problem from getting worse and prevents structural damage.
No: a good professional uses approved products and adapts the treatment to your home. They provide safety instructions (ventilation, areas to avoid) and choose a method suited to homes with children and pets.
It depends on the species to be treated and the extent of the infestation: identification, treatment, follow-up. For example, for rodents: inspection + sealing + traps; for wasps: locating the nest + removal. The technician will give you a timeframe when providing the quote.
Not always. It depends on the treatment used and the areas involved. If chemicals or confined areas are being treated, you may be asked to temporarily evacuate or isolate certain rooms.
A reputable company offers a written guarantee so that if the pest comes back, the company returns to treat it again. Be sure to check the duration and conditions.
Some effective measures: seal cracks/exteriors, keep areas dry, store food in airtight containers, remove debris around the house, monitor humidity.
Every building is different: access points, humidity, structure and surrounding vegetation. Even a clean home can be invaded if there is an entry point or if an infested piece of furniture is brought in. Local factors (neighbourhood, height and location of the nest) also play a role.
The wasps look for another way out, often into the house through a wall or ceiling. Never block the entrance of an active nest: have it treated first, and seal the opening only once there is no more activity.
No. The colony dies in the fall and only the new queens survive the winter, somewhere else. In spring, they build a new nest, sometimes in the same spot if it stays well sheltered: sealing gaps in soffits and siding reduces that risk.
The most common one is the bald-faced hornet, which is actually a wasp: it defends its nest aggressively and can sting several times. The Asian giant hornet, spotted in British Columbia in 2019 and 2020, has never been reported in Quebec.
