Good morning all,
I saw some wasps going in and out of my vent brick into the space under the
floorboards and I'm worried there could be a nest.
We've just had a carpet laid in the living room where the access hatch is
and I don't want to lift the carpet again.
Is there a product to kill the nest, like the ant bait stuff, that they take
back with them and poisons the nest?

Nippon powder - the same stuff

spray it where they land to enter
