Wasps are yellow and black in colour and are social insects living in nests of up to around 10,000 worker wasps. Wasps can grow up to 19mm in size and are mainly found in gardens, woodlands and meadows.
Wasps live in paper nests, made by chewing small amounts of wood from trees, reeds or garden fences. In gardens, wasps will not construct their own burrow but will use existing ones abandoned by other animals. Wasps can also live in garden sheds, garages and lofts where they will construct their nests within the eaves. They will defend the nest and will sting anything that disturbs them.
