This is the one page on this site where the practical advice is: do not do it yourself. Here is why, and what to do instead.
Identify where they are going in, keep everyone away from it, and have it treated professionally. Treatment is £90 fixed cost with our guaranteed service.
We give DIY advice freely on most pests on this site. For wasp nests we do not, and the reason is that the failure mode is a person being stung repeatedly by an angry colony while up a ladder.
Elsewhere on this site we tell people how to deal with ants themselves, when a mouse problem might resolve with a threshold seal, and that most spider enquiries do not need treatment. We are not squeamish about talking people out of work.
Wasp nests are the exception, and the reason is arithmetic. A mature nest can contain several thousand wasps. Unlike bees, wasps sting repeatedly, and a colony that perceives an attack responds collectively and quickly.
The people who come off worst are not the ones who did nothing. They are the ones who went up a ladder with an aerosol.

Most wasp nests that trouble people are above head height — soffits, eaves, roof spaces. Dealing with one means being on a ladder, at height, with both hands occupied, next to a colony that is about to become extremely agitated.
The sting is not usually what causes the hospital visit.
If anyone in the household carries an adrenaline auto-injector, make sure everyone knows where it is while there is a nest on the property.
A photograph from a safe distance settles it. Send one with your enquiry if you are unsure.
Nests are not reused, so an old nest is not a source. But the same locations attract new queens each spring:
£90, fixed, guaranteed, and considerably safer than a ladder and an aerosol.
We advise against it. A mature nest holds several thousand wasps, they sting repeatedly, and most nests are at height — the ladder is usually the real danger.
No. Wasps chew a new exit, and in a wall or roof that often means into the building.
Poorly. They are designed for individual insects, agitate the colony, and rarely reach the nest interior.
No. Wasps navigate toward light, and at night the light is the torch in your hand.
Move away immediately, wash and cool the area, consider an antihistamine. Call 999 for breathing difficulty, facial or throat swelling, dizziness or collapse.
Wasps are bright yellow and black, smooth and sharply waisted. Honey bees are furry and golden-brown — call a beekeeper for those.
For a period, yes. Foragers return to the nest afterwards.
No. But the same locations attract new queens each spring.
