There are two types of wasp, the social kind and the solitary one. The social wasps are those that build nests that bring us trouble and problems. The solitary wasp, as the name implies, is a loner and lives by itself. Social wasps are the ones we should be careful with. These type are capable of building a population of 5,000 to 10,000 wasps per nestling. That’s an ugly number especially if the flying vermin decide to build their nest right next to your home.
