Questions & answers about wasp nests
Sarah asked:
Hi Paul I have noticed lots of wasps entering a hole at the side of my extension. It is difficult to get to as you have to walk inbetween the neighbours extension and my conservatory (which has been built infront of my extension). There is a lot of activity at the moment and the entrance is a hole under a plank. Please advise, my husband sprayed a can of rentokil nest destoyer spray at dusk but it seemed to make no difference and how do you know where to spray as the plank has a long hole running across it and they are entering underneath the plank. Awaiting your kind attention. Regards Sarah.
Paul Sweet replied:
Hi Sarah, most pest controllers use a dust based insecticide pumped into the entrance or hole where the wasps are entering. This is residual dust that is then carried into the nest by the wasps which become contaminated as they walk through it. The foam wasp nest destroyers will not work in these sorts of situations, as the nest needs to be accessible to spray the foam onto it. The best course of action is to have a pest controller come out and deal with them for you. If you are in our area, we can arrange a visit, or if you are not in our area, please use our sister site to find your local pest controller. http://www.wasp-control.co.uk Hope this is of some help.

Michael asked:
Just been in the loft and there are hundreds of dead wasps on the floor. Why are they dead. Also loads of dead wasps coming out of the air brick by the front door. Worried if I have a problem that will eventually kill me
Paul Sweet replied:
Michael, if all the wasps are dead, what's the problem?
Becca asked:
hi i have just cut some trees back outside my house and now have wasps flying in and around them,is it possible they are building a nest or are they just collecting the sap from where the branches have been cut?.What would be the best time to look into the trees to see if there is a nest as i am not to keen to get to near them ? thank you .
Paul Sweet replied:
Hi Becca, sorry for the delay in reply! It is possible that a nest was in the trees and you accidentally destroyed it while cutting the trees? Wasps will feed on aphids and also nectar from certain trees, and this could be what's 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 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 reasonably close. Regards Paul.
