Vespula Germanica and Vespula Vulgaris
Wasps are social insects, living in large colonies of between 3000 and 5000 individuals, inside wasp nests made in soil banks, roof spaces and cavities, trees and walls, with workers establishing sometimes very large nests around the queen’s initial cell and ensuring she has a plentiful supply of food.
Wasps are most aggressive towards the end of the season, when the new queens have been fertilised and flown away to hibernate through winter making workers redundant. It is this time when they can be most aggressive as they feed on fermenting fruit giving a “tipsy” behaviour and react badly towards anybody interfering with them.
