The short version: do not do it yourself. This is the one pest where the DIY attempt is genuinely dangerous rather than merely ineffective.
Have it treated professionally. £90 fixed cost, guaranteed. The colony is treated at the nest, foragers carry the treatment in, and it dies within a day or two.

View Wasp Nest Removal Wealdstone →The most common and most damaging mistake. Wasps chew through plasterboard, insulation and soft mortar. Blocked outside, they come inside — into the room, not the garden.
It does not reach the nest. It does provoke the colony into defending it, from a distance of a few feet, with you holding the can.
This is where the real injuries come from. Wasps defending a nest at head height, on a ladder, produces falls. The sting is rarely the serious part.
It happens every summer. Roof fires, burns, and a nest that is still there afterwards.
A visible nest under an eave or in a shed is a colony of hundreds to thousands. Knocking it down releases all of them at once.
Wasps defend the nest. Anything that reads as an attack on it gets treated as one, and you are standing next to it.
From late August the colony structure breaks down, the workers stop rearing brood, and their behaviour changes — more interested in sugar, less predictable, more likely to sting. A nest that was tolerable in July can become a real problem in September.
If it is late in the season and near a door, balcony or window, it is worth dealing with rather than waiting for the first frost.
