Indeed they will, they will even chew through concrete to get out.. or will they find another exit?
CorrectJust because they are coming and going through the air brick does not mean that is the site of the nest
And do it at night, that is once they have all returned to the nest.I have used Raid wasp nest destroyer spray with some success in the past.
Stand well back and blast that through the holes should do the trick.
Exactly, I have them drop through a ceiling, into a family living area, where they had built a nest mainly from rafters and plaster board.Wasps are generally a bad idea in buildings: they will tunnel though mortar and chew up timber, sometimes creating new entrances into rooms where they are unwelcome. It's fine for them to be in hollow trees etc, but they will cause damage to buildings.
1 gallon of unleaded and a match is usually fairly effective...
Wasps only nest in one place once then move on. So next year they move on
The queen then lays half a dozen eggs that will become new queens, these leave the nest late autumn to find a nesting site, where they hibernate until the following spring
The minute the petrol or anything else "foreign" for that matter, touches the nest, wasps go on the attack, I wouldn't recommend that tbh1 gallon of unleaded and a match is usually fairly effective...
I'd think that would depend on whether the match was applied before or after the petrol touched the nest, however, 'after' is not recommended for reasons unrelated to the wasps.The minute the petrol or anything else "foreign" for that matter, touches the nest, wasps go on the attack, I wouldn't recommend that tbh![]()
Commin' over 'ere, nickin' all our British wasps jobs, Brexit'll sort 'em out..."German wasps"
The first time I was acquainted with the little darlings was about 20 years ago.Commin' over 'ere, nickin' all our British wasps jobs, Brexit'll sort 'em out...
(With apologies to Snoopy)
Ten, twenty, thirty, forty, fifty or more
The Bloody Yellow Bastards chased Cobra out the door
Eighty wasps died tryin' to end that spree
Of a Big Pink snake against Germany...

Having been there done that, next day we shoveled up half a bucket of the little "insects" best way to go but dress up like a terrorist they can still get a bit cross!Had this many years ago in a previous house. Was advised to wait until nighttime when they had returned to the nest. To spray through air brick and then block air brick and leave like that for a few days.
Good luck.
Not many people realise that dead wasps can still sting, don't stand on a dead one in bare feetbest way to go but dress up like a terrorist they can still get a bit cross!
The first time I was acquainted with the little darlings was about 20 years ago.
I'd just injected a Neurotoxin under the (low) roof tiles of a barn conversion.
The wasps "Exploded" as they normally do, when you hit the spot, stepping back about 20 feet to watch them spiral out of control, dropping little fighter planes from WWII is generally sufficient
and a safe distance to remove the veil.
Erm, not 50 feet, 100 feet, 100 yards and the barstewarts were still coming after me!
I put the veil back on PDQ I can tell you
That was my first encounter, ever since then I have been a little more careful![]()
LOL It'd be so fat in a few seconds that it wouldn't fly for a fortnightSounds like you need to trade in one of them hawks for a Bee Eater![]()

All you have to do is poke them, that's enoughGerman wasps are okay as long as you don't mention the war.
Actually no they don't. the minute amount of "meat" is contained within the Chitin shell and this eventually just turns to dust.A large quantity of dead wasps in a wall cavity could cause a bit of a stinK. You probably wouldn't notice a few decomposing but a whole (or even half!) nest full of the buggers will make your eyes water.
That's different, Wasps nest are made of spit and wood, and contain no honey ergo nothing to smell.dead bees in a blocked off fireplace, I can assure you that they do hum
