If you live in Vancouver or the Lower Mainland, you may notice wasps and hornets becoming especially active in late summer and early fall.

So, how long do wasps and hornets last in Vancouver before winter?

The answer depends on the weather and species, but wasps can remain active well into the fall, especially during a mild Vancouver autumn.

When Do Wasps and Hornets Disappear?

As temperatures drop, most of the colony gradually dies off. According to the Province of British Columbia, the workers and brood die in the fall, while mated queens survive the winter and establish new colonies the following spring.

This means an active nest can continue to be a problem through September and October, particularly when temperatures remain mild.

By winter, most wasp activity will have stopped. However, if you have a nest near your home, it’s not always a good idea to simply wait for the cold weather.

Why Are Wasps So Active in Fall?

Late summer and fall provide plenty of food sources that attract wasps, including:

• Fallen fruit
• Garbage and recycling
• Sugary drinks and outdoor food
• Pet food
• Compost

Keeping garbage covered, removing fallen fruit, and covering food and drinks can help reduce wasp activity around your property.

Should You Wait Until Winter?

If a nest is high in a tree and away from people, it may eventually become inactive naturally.

However, nests near doors, patios, children’s play areas, decks, attics, walls, or other high-traffic areas can pose a sting risk while they remain active.

You should also be cautious if you see wasps repeatedly entering a hole in your siding, soffit, roofline, or another part of your home. This may indicate a nest inside a wall or other concealed space.

Don’t seal an opening while wasps are still active. They may find another way into your home.
