Paper wasps are social insects commonly found around homes and other buildings, constructing their distinctive nests under the eaves of roofs, in trees and shrubs, under decking, in pipes and in other suitably sheltered locations. They are most active and prolific during the summer months. 

  There are a number of species found in South Africa, including an invasive species, the European paper wasp (Polistes dominula). The different species vary in size and colouration. Like bees it is only the females that have the ability to deliver a painful sting. When a nest is disturbed the wasps often react by vigorously vibrating their wings as a warning. If further approached or provoked they may launch a squadron of aerial defenders to ‘encourage’ the ‘threat’ to rapidly vacate the immediate area. Fortunately though, and generally speaking they are docile creatures and will not chase you. They are unlike bees, who can only deliver a single sting – their barbed stinger remains embedded in their victim, the bee thus makes the ultimate sacrifice in defense of the colony. Paper wasps on the other hand can sting repeatedly with no ill effect. The level of pain experienced varies from species to species. Some species can deliver an extremely painful sting while others are only moderately painful. Most stings only result in pain and localized swelling, however there is always a risk of an allergic reaction in sensitive individuals. The pain usually subsides within 10 to 15 minutes whereas the swelling may persist for a number of days.
