Elimination

Case No. 1: Visible nest

In the summer, it is important to ensure people and pets keep away from the area while the nest is being destroyed. If the nest is visible (gray ball), spray Maheu&Maheu Wasp and Hornet Killer in the nest opening.

Ideally the work should be done at night (in total darkness). Wear coveralls buttoned up at the neck and wrists and stuff the pant legs into your socks. A protective hat with netting and thick gloves provide even greater protection.

Place a flashlight on the ground nearby. Escaping wasps will be attracted to the light beam. It is also a good idea to have some Maheu&Maheu Flying Insect Killer handy to protect yourself because its spray mist kills insects immediately.

Do not try to dislodge the nest by spraying it with water. The wasps will become more aggressive and will remain in the vicinity. They may even try to repair the nest. It is best to remove the nest shortly after killing the wasps because other insects that come to feed on the dead insects may decide to set up house in it.

If you find a visible nest in winter, you can remove it without fear because all the wasps inside will be dead.

Case No. 2: Hidden nest

Some species, such as the German wasp, build their nests in inaccessible places, especially inside walls or in building structures. The nest is therefore not visible, but wasps' comings and goings at a specific point can indicate its location.

In this case, direct intervention on the nest is not always possible. However, regular observation of wasps' routes can help to confirm their point of entry. A Maheu&Maheu Glue Trap can be installed near the entrance: wasps will stick to it, which will help reduce their numbers more quickly.

As with visible nests, it is strongly recommended to intervene at night and to wear protective clothing to avoid bites: zipper suit, gloves, mosquito net.

Finally, never obstruct the entry point with any caulking or other material until all activity has ceased, as this may cause wasps to find another path—sometimes into the house.

Do not hesitate to request the intervention of a qualified technician from our team if the nest is not visible or if you prefer not to approach it.

Actions

  • Work after the night falls
  • Spray visible nests (paper nest) with insecticidal foam
  • Put extra glue traps in places where insects land if the nest is hard to get at
  • Request assistance from one of our pest management experts

Prevention

  • Seal off outside cracks and crevices where insects could get in and build nests in structural voids.

Description and development

There are many wasp species in Quebec, and their coloration (usually yellow and black) and size vary by species. Generally speaking, adult wasps measure from 10 to 25 mm long. They have slender waists (junction between the thorax and abdomen) and their bodies are quite elongate.
Wasps are very widespread in Quebec. They are social insects that live in colonies, with one or more queens (fertilized females), workers (sterile females), and males at certain times of the year.

Habits

Like bees, wasps are very useful insects because they pollinate plants. However, when wasps build their nests near homes or even in the foundations of houses, they can become bothersome. If disturbed, they will not hesitate to defend their nests by stinging.

In contrast to bees, which can only sting once (because they leave their stingers in the victim’s skin), wasps can sting many times.

Tips

It is not recommended that people with insect sting allergies perform these tasks. Ask a friend or pest management specialist for help.
