The winter 2024-2025 was abnormally warm in Quebec, followed by an early-onset spring. These conditions allowed the wasp queens to exit their diapause earlier and start building their nests quickly.

Unlike 2024 where the season had started slowly despite a mild winter, this year, wasp activity is clearly increasing. If the weather remains mild during the construction holidays, we can expect a sharp increase in active populations from early August, which will necessarily lead to a significant increase in demand for intervention.
Wasps usually build their paper nests, visible when suspended outside on a branch or ledge. Some species prefer ground burrows or crevices in developments, while the very common Germanic wasp often settles in structural voids inside buildings. It is important to note that the entry point of wasps is often far from the nest itself, which may not be visible. Therefore, one should never plug the holes through which they enter a dwelling, as this could block them inside, forcing them to disperse in inhabited rooms.
If the prevention of their presence remains difficult, it is useful to remember that wasps play a significant ecological role, notably as pollinators. However, when their nest is too close to frequented spaces or in the presence of people with allergies, it becomes crucial to act quickly to destroy the colonies. In fact, their number can grow exponentially until the first autumn frosts. For this matter, our website offers practical advice to eliminate wasps when their presence becomes annoying.
Finally, false nests are not an effective solution, and it is common to find several colonies, sometimes of different species, on the same property. It is however possible to limit their number by using attractive traps placed at a distance from the outdoor living areas. These traps, equipped with a liquid bait, where they become trapped and are unable to escape.
