Social wasps will defend their nests aggressively and will attack if their nests are approached. Multiple stings from the larger wasps such as hornets are dangerous, and the victim needs to be hospitalised immediately. Some victims have died from hornet stings. In Singapore, the common hornets are the banded hornets, the lesser-banded hornets and the slender-banded hornets. These are black with an orange band on the body.
Other social wasps are smaller than the hornet and will also attack if their nests are disturbed. The night wasps nest in bushes and enter our homes because they are attracted to light. They will sting if they land on one’s skin. They usually sting just once.
