Wasps are
social insects and form large colonies, or nests, which are socially structured and highly
organised. Wasps are a widespread pest during the summer and cause fear and concern in many
people because of their powerful stings especially as some species are quite aggressive.
Their characteristics. The queen usually
spends the winter in a warm protected site often located in lofts, attics, wall cavities or in
the ground. As many as 30,000 wasps can populate a nest. 

The treatment. The wasps nest will be treated
directly. If the wasp nest cannot be located, treatment may involve the use of perimeter traps.
Alternatively, insect screens on doors and windows will help stop wasps entering buildings and
the installation of electric fly killers will help to control wasps if they do get inside
premises.
