A steady two-way stream at one point in the roofline is a nest inside the structure. You will not see it, and that changes nothing about the treatment.
Inside the structure, somewhere behind the point they are going in. A steady two-way stream at a soffit gap, under a tile or at an air brick 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 for 30 days.
Wasps around a bin, fallen fruit 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 |
| A junction between two roof pitches | Nest in the void behind it |
| Behind a hopper head or gutter | Nest in the eaves |
| At a dormer or loft conversion junction | Nest in the void behind |
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.

A wasp colony sealed out of its own entrance does not give up. It finds another way, and the other way is usually into your building.
A specific pattern worth recognising.
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.
Nest inside a roof or wall? Still £90 fixed cost in Stanmore, guaranteed for 30 days.
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. A loft conversion, dormer or extension roof creates more places for a nest, not a bigger bill. Still £90.
No. Wasps chew through plasterboard and insulation and end up inside the building — and in a loft conversion that room may be a bedroom.
Usually a nest in the roof void above or beside it, with wasps coming through a light fitting, downlighter or loft hatch. Do not block the gap.
Yes, if it grows large enough. The paper structure gets heavy and plasterboard is not built for it.
Usually yes, once the nest is dead — the same gaps let in squirrels, rodents and birds, which matters more here than the wasps alone.
