Wasps can be social and build nests together or solitary and lay a single egg in a crack or crevice.
At their peak a social wasps nest can contain 6 to 10 thousand wasps which tend to be more aggressive toward the end of the year when the workers die off.
Wasp stings are painful and can be dangerous. Their presence will spoil the pleasure of drinks on the patio and food from the barbeque, they also come into the premises looking for sweet treats.
As well as treating nests Pestokill also provide wasp traps to attract the wasps toward an area, once inside they cannot escape.
