Paul Sweet replied: Hi Becca, sorry for the delay in reply!

It is possible that a nest was in the trees and you accidently destroyed it whilst cutting the trees?

Wasps will feed on afids and also nectar from certain trees and this could be whats happening.
If there is a nest present, there will be a high concentration of wasps in a localised area, if the nest has been destroyed, they will look lost as if they are there without a purpose. Likewise, if the nest is present you should be able to follow where they are heading too. If they are just feeding on smaller insects and nectar, then they will be spread out across a wide area across the trees. However, if in any number then that would indicate that a nest is fairly close.
Regards
Paul.

Paul Sweet replied: Hi Kate, the pest controller that undertook the job should have advised you on what to expect.

It depends on the size of the nest and what he used to treat the nest.

We use Ficam D which is a dust. This is fast acting and also kills the entire nest, not just the ones that were in the nest at the time of treatment.
We always advise our customers to stay away from the area of the nest for at least an hour, sometimes more if it is a big nest.

There will be dead wasps on the floor underneath where the nest was and if you tread on them with bare feet they can still sting.
Hope this helps.
Regards
Paul
