How to prevent wasp nests around the house?

The arrival of warmer weather also means the return of outdoor insects, and wasps are often at the top of the list of unwanted guests. Unlike bees, wasps can be aggressive and sting repeatedly if they feel threatened. Rather than having to deal with an aggressive colony in the middle of summer, the best strategy is to prevent wasp nests. Here are the key steps to discourage queens from choosing your property to build their kingdom.

1. Inspect and seal potential entry points

At the very beginning of the season, a queen wasp seeks a dark, warm, and sheltered spot to begin building her nest. Cracks in exterior siding or structural openings are her preferred targets.

Seal the openings

Inspect the frames of your windows, your doors and the brick joints.

Protect the upper access points

Make sure the screens on your vents, dryer, and soffits are in perfect condition. An opening in the attic can lead to a major and hard-to-reach infestation.

Inspect the secondary structures

The undersides of balconies, sheds, empty birdhouses and unused electrical boxes should be checked regularly.

2. Eliminate food and water sources

Wasps are attracted to two main things: protein (to feed the larvae) and sugar (for adult energy).

Secure the bins

Use airtight containers for your waste and compost. Clean them regularly to remove sugary or meat residues that give off attractive odors.

Manage outdoor meals

When barbecuing or eating on the patio, cover your food and put away your plates promptly after eating. Avoid leaving open cans of juice or soda lying around.

Pick up the fallen fruit

If you have fruit trees on your property, regularly collect the fruit that falls to the ground, as it ferments and attracts wasps in large numbers.

3. Use natural repellents

Certain odors act as natural repellents and can encourage a queen to seek out another plot of land than yours.

Aromatic plants

Planting mint, thyme, wormwood or lemongrass near your outdoor living spaces (terrace, pool) helps to keep insects away.

Essential oils

A mixture of water and a few drops of peppermint, clove and lemongrass essential oil sprayed under roof edges or balcony railings can disrupt their location.

Too late? The nest is already built?

Preventive measures are effective in discouraging a nest from being built, but they become completely useless and dangerous once the wasp nest has started to grow. Attempting to remove, spray with a hardware store product, or block access to an active nest yourself is the number one cause of serious accidents and multiple stings. Wasps release alarm pheromones that trigger the entire colony to attack as a group to defend the queen.
