The test is traffic, not numbers. Wasps flying about are foraging; wasps going in and out of one specific point are a nest.
Watch the traffic. Wasps flying around a garden are foraging and mean nothing. Wasps repeatedly entering and leaving the same specific point — a gap in a soffit, a hole in a wall, under the eaves of a shed — means a nest is inside.
Ten minutes of watching from a safe distance answers this. Do not go looking for the nest itself.
This is the whole diagnostic and it costs nothing but ten minutes.
Stand back — ten metres is ample — on a warm day, ideally mid-morning or early afternoon when activity is highest. Watch.
| What you see | What it means |
|---|---|
| Wasps flying about the garden generally | Foraging. Could be from anywhere, including next door. |
| Wasps interested in a bin or fallen fruit | Feeding. No nest indicated. |
| A few wasps near one area | Possible. Keep watching. |
| Wasps repeatedly entering and leaving one point | Nest inside |
| A steady two-way stream at one hole | Established nest |
| Wasps disappearing under a soffit or tile | Nest in the structure |
The key word is repeatedly. One wasp going into a gap proves nothing. A continuous procession in and out of the same opening proves a great deal.
Sheds, garages and outbuildings are among the most common nest sites, because they are undisturbed, sheltered and full of the cavities wasps like:
Worth stating plainly, because the instinct is strong and it is how people get hurt.
You do not need to find the nest. You need to find the hole they keep using. Those are different searches, and only one of them is safe.
Booking treatment does not require you to have seen the nest. The entry point is enough.

Plenty of wasp activity has nothing to do with a nest on your property:
If there is no two-way traffic at any single point on your property, treatment at your address will not change anything.

Then it is theirs to arrange. We can only treat with the property owner's agreement.
Often it is the ideal time — a nest in April or May is small and the whole thing is far more straightforward than in September. Same £90 either way.
Same £90 wherever the nest is on the property — shed, garage, roof or hedge — in Harrow Weald and the surrounding areas.
Watch from a safe distance. Wasps repeatedly entering and leaving the same specific point means a nest inside. General flying about means foraging.
Under the eaves, in roof spaces, behind undisturbed stored items, in wall cavities, under the floor, and inside rolled parasols or tarpaulins.
No. You need to find the hole they keep using, not the nest itself — and opening a shed or moving boxes is how people get stung.
Wasps strip wood fibre to build with, leaving fine parallel scrapes on bare timber. It means they are building nearby.
Yes. Foragers range widely, so wasps in your garden may be nesting elsewhere. Without two-way traffic at one point on your property, treatment at your address will not help.
Wasps are bright yellow and black, smooth and sharply waisted. Honey bees are furry and golden-brown — call a beekeeper for those.
Colonies die off in late autumn and nests are not reused, so you can. It depends how close it is to where people go, and whether anyone is allergic.
No — it is the same £90. But it is a more straightforward job than the same nest in September.
Do the ten-minute traffic watch from a safe distance, then tell us where they are going in.
