Wasps become a nuisance to humans mainly in late summer as the weather gets cooler and they are more likely to sting. Unlike bees, wasps are able to sting repeatedly. Wasp stings are usually irritating but harmless. A minority of people are hypersensitive to stings and in certain cases can cause a severe reaction.
You are strongly recommended to seek professional help in dealing with a problem wasp nest. The council provides a pest control service for the treatment of wasp nests in domestic properties. Fully trained pest control officers will survey the infestation and then place treatments in the most appropriate locations. Follow up visits will be made in order to ensure the success of the treatment.
If you are experiencing high numbers of wasps in your home or garden it is likely that there is a nest nearby. If the location of a nest is likely to put people at risk, then it should be treated immediately.
