We've just destroyed the first nest of the year. The cheeky devils were
taking over a bird box hanging in the courtyard outside the tea room's
back door. It would have been a nightmare for everyone! However, the
pest controller did warn me that they love the sort of humid weather
we've had and that the professionals think this is going to be a bad
year for wasps. Or a good year, if you're a wasp, I suppose!

A neighbour called in early this morning to ask for some advice on
what to do with a wasps nest near their front door. Tried to advise
her to get a pest controller in but she seemed to think that it was a
job that her husband would really enjoy (having failed to persuade me
to volunteer).

There's a 'spray' you can get for wasps nests that comes out as a jet
of foam, with a range of about 10 feet IIRC, so you can apply it to
the entrance of the nest from a safe(r) distance. Best applied in the
early evening when the wasps are returning home. Then as they trample
over/through it, they carry the poison into the nest. By next morning,
most of them are dead, and those that aren't are pretty far gone.


The one I have had best results with is the powder again sprayed around
the entrance to the nest, or any other place they walk through; I had
them one year going into the glasshouse after the grapes, they all
entered through a small gap in the corner, dusted that and in a day they
were gone.
