Wasps
If a nest requires treatment, it is best to get a qualified pest control operative to deal with the problem. Do not try to deal with them yourself. Disturbing a nest can dangerous, particularly in a confined area such as a loft space.
Although wasps are generally disliked because of their sting, most species will only sting when the wasp is aroused or frightened.
As the weather gets colder in the autumn, all the wasps die except the new queens, which fly away to find hibernation sites. The old nests are not re-used the following year. It will only be necessary to treat wasp nests which pose a particular danger to you or your family. There is usually no need to remove a wasp nest following treatment.
