Hey luis .....u arnt related to me .....are you .....just see your name......my cousins name ......im a sanchez loool
If you have a wasp nest behind air bricks etc and you kill the wasps , leave the nest where it is as wasps respect other colonies territory and one look at the nest from 'scouts ' and they'll bugger off never to return .
Nasty little ba$tards - one stung me last week proper painful - I flicked it off then it landed on the dog and stung her as well - dog went all dopey for the next 3 hours - didn;t even manage to kill the damn thing after all that (the wasp not the dog).
Fire arse Been a nightmare this year we went on holiday to come back and find they had killed one of my bee hives severely weakened the others and nicked all this years honey
Sorry to hear that matty. I take my hat off to you few bee keepers , battling to prevent the rest of us from starving to death.
If you don't mind a lack of air flow which could cause your wood floor to become damp and rot in time. Never leave a block or part blocked air brick in this way if may cost you in the long run.
The nest in my instance was not directly behind the air brick , but to one side out of the draught , which I am sure is not a random act by the colony. You are of course correct regarding keeping air bricks clear.
