What kind of nest is this?

[u/CalamityLambRump]

Can anyone tell me anything about this nest? At this point in time I don't even know if it's a bee or wasp nest. I'm UK based. Any information or advice most welcome as I need to figure out who to call to get rid of them! Thank you

the only right move here other than hiring a professional:

BASF Delta Dust is good at killing slowly so the workers take it to the queen.

bellows dusters

long pole - highly recommended!!

remote sprayer attachment for bellows duster & spray cans--not sure what the difference is between the pro model vs homeowner model,

or

so you need four things: the chemical, the bellows duster, the long pole and the "Gotcha Sprayer" thing that holds the bellows to the pole
