A steady two-way stream at one point in a wall or roof is a nest inside the structure. You will not see it, and that changes nothing about the treatment.
There is a nest inside the structure. A steady two-way stream at a single point — an air brick, a soffit gap, under a tile, a crack in render — is the entrance to it.
You cannot see the nest and you do not need to. Treatment is applied at the entrance; foragers carry it in. £90 fixed cost, guaranteed.
Wasps around a bin, a fallen apple or a drink outside are foraging and tell you nothing about a nest.
| Where | What it usually is |
|---|---|
| Soffit or fascia gap | Nest in the roof void or eaves |
| Under a roof tile or at a ridge | Nest in the roof void |
| Air brick | Nest in a wall cavity or subfloor void |
| Crack in render or a mortar joint | Nest in a wall cavity |
| Gap around a pipe or vent | Nest in a wall or floor void |
| Balcony soffit or underside | Nest in the balcony structure |
| Behind a hopper head or gutter | Nest in the eaves |
The nest is frequently some distance from the entry point. Wasps travel inside the void, which is why treatment goes in at the entrance rather than at a spot you have guessed at.

By late season a mature nest can hold several thousand.
Honey bees do occupy cavities and chimneys. We will not treat them and will point you to a local beekeeper. Golden-brown and hairy rather than yellow-and-black and smooth.
The colony dies at the end of the season. That may be a long way off, and the nest grows continuously until then.

A nest inside the structure. That point is the entrance to it.
No. Treatment is applied at the entry point and foragers carry it into the nest.
No. Wasps chew through plasterboard, insulation and mortar and end up inside the building instead.
Often some distance from the entry point — wasps travel inside the void.
