Wasp Season in the UK: What You Need to Know

Wasps are most active in the UK between June and September, with nest populations peaking in late summer. A single nest can contain up to 10,000 wasps by August, making late-season nests particularly dangerous.

The Wasp Lifecycle

Queen wasps emerge from hibernation in spring and begin building a new nest. Worker wasps hatch in early summer and the nest grows rapidly. By late summer, the colony produces new queens and males. Once the new queens have mated and found a hibernation spot, the original colony dies off in autumn.

When to Act

The earlier you treat a wasp nest, the easier and safer it is. A nest treated in May or June will be much smaller than one treated in August. If you notice wasps entering and exiting a specific point on your property — such as under roof tiles, in a shed, or through a gap in brickwork — contact a pest controller promptly.

Why Not to DIY

Attempting to remove a wasp nest without professional equipment is extremely dangerous. Disturbing a nest can trigger a mass attack, and wasps can sting multiple times. For anyone with an allergy to wasp venom, this can be life-threatening.

What We Do

Our technicians wear full protective equipment and apply a professional insecticide directly into the nest entrance. The colony is typically eliminated within 24–48 hours. We can also remove the inactive nest afterwards to prevent secondary infestations.
