As we get later into the season we find that the usual treatment of spraying the entrance to the nest will result in failed treatments and call backs.
I think the lower numbers of wasps entering the nests leads to less chemicals getting into the heart of the problem.
Hatching Queens wonder from the nest and will drop into living areas of the house.
Making sure your chemicals enter directly into the centre of the problem will reduce these problems.
