During the winter months solitary fertile queen wasps will be hibernating, on their own, in tucked away places in loft areas, sheds, wood pipes. Our photograph shows several sleepy queen wasps hibernating in an unused drawer.
When the weather starts to warm up in the Spring she will emerge from her hibernation place, feed and search for somewhere to start to build her new nest. She will start her new nest from a single cell in places such as lofts, sheds, porches, garages. She will need to establish a colony as quickly as possible. For queen wasps this is a deadly race against time which most of them will lose.
We start treating active wasp nests from end of June to end of September once a nest is established and busy enough to locate and treat effectively.
