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 Inc., our certified technicians are available 24/7 to remove wasp and hornet nests in Montreal, Laval, and on the South Shore.
We use products approved by Health Canada and safe, environmentally friendly methods tailored to each situation.
✅ Rapid response — ✅ Certified products — ✅ Written warranty for up to 6 months
A wasp nest can develop in just a few days, reaching hundreds of insects.
To wait is to risk:
Multiple bites or a collective attack
Rapid spread to other areas of the house
Property damage (plaster, insulation, woodwork)
Found in eaves, hollow walls, fences, or attics
Often invisible until they become dangerous
Can cause long-lasting infestation if left untreated
Removal within 24 hours for any active nest
Complete inspection + targeted treatment around the area
Use of professional safety equipment
Preventive treatment to avoid reinfestation
Not all flying insects pose the same risk.
Here's how to tell them apart 👇
Very aggressive in summer
Papier-mâché nests (roofs, walls, shrubs)
Can sting multiple times
Very dangerous near homes
Larger and noisier than wasps
Very territorial, attack in groups
The European hornet nests in tree trunks or roofs.
The Asian hornet (observed in Quebec in 2025) is invasive and must be eradicated immediately.
Not very aggressive, useful for pollination
Can become a nuisance if they nest in a facade or shed
Business travel recommended to preserve their ecological role
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.
Weather conditions have encouraged massive reproduction of wasps and hornets in Montreal.
👉 Emergency calls have jumped by 40% according to local reports.
Attempting to destroy a nest yourself is dangerous:
Wasps react violently to vibrations and heat.
Consumer products are not very effective.
Improper handling can cause a collective attack.
Our teams wear full protective suits and use telescopic poles and pressurized sprayers to safely remove the nest.

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 prevents the situation from worsening and 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 that is safe for 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 (a few months) to ensure that if the pest returns, it will intervene 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, humidity, structure, surrounding vegetation. Even a clean house can be infested if there is a point of entry or if contaminated furniture is brought in. The local context (neighborhood, type of building in Laval) plays a role.
