We have discovered due to me being stung yesterday evening that we have a wasps nest in our post box.
I have been to Our Marie for advice and she suggested using a spray and also gave me a number of someone who maybe able to help.
Due to their been quite afew I think it would be impossible in case they swarm.
Apparently pompiers no longer help.
Does anyone have any advice that may help.

There are indeed spray-bombs which shoot a stream of wasp-toxic liquid from several meters away. I actually brought one from the USA, but I'm pretty sure I've seen them in stores here--I protected myself with an old bee-keeper's veil, but that really did not seem to be necessary. We had a nest in our eaves, and I had to climb up a tall ladder to access their nests--it worked, but the vapors from the spray may have caused our dog to have a brief seizure, so I'd be careful about it. After the wasps were dead, I plugged up the chink in the masonry which had been their doorway, and in the seven years since, we've had no more problems with them.

The Raid stuff in the supermarkets is very good. The one in the black spray can for guepes and frelons.

I think there is a good time to spray it but I can't remember as its a few years since we used it on the frelons. It is virtually instantaneous.

Thanks guys off to buy some spray.
Such a cheek : I mean move in without paying any rent or a bond and then sting the landlady . They are on the way out no squatters rights here in St Marien .

Use the spray in the evening, as the wasps all come home for the night. That way you won't get any distraught relatives left, bent on revenge.

Thanks for that advice and will do.

We had a small wasps nest on our greenhouse. Judicious application of a paint scrapper knocked it down, the wasps flew off, and I crushed the remains of the nest. Job Done!

The paint-scraper technique has much to recommend it, ecologically.....the chemical warfare approach may be necessary, though, when the nest is inaccessible.

Mmmm not sure if brave enough for paint-scraper approach through a letter box .
Yes think the spray can best idea when they are all tucked up fast asleep I will take my revenge lol
