Wasps are social insects forming large colonies inside nests constructed of chewed
wood and saliva, they will construct their nests in roof spaces, hollow walls, trees,
embankments and are often associated with domestic housing.
There are two main wasp species in the UK that are deemed to be a pest, these are
the Common Wasp (Vespula Vulgaris) and the German Wasp (Vespula Germanica) both are
very similar in appearance having only a few subtle differences which are the markings
on the head and body. Both species can sting but do not normally become a nuisance
until late summer, however there are instances where wasps construct their nests
in areas that are frequently used by people presenting a possible threat to health,
making the need for control necessary.
After the treatment of a nest the complete elimination of the wasps normally takes
about 24 hours.
