Wasp Habits & Behaviour
Wasps are social insects and form colonies. The wasp colony will reside in a nest which they build in a suitable area. For them, a suitable area would be a cavity in a wall or the roof. Wasps can also build nests in soil or trees, usually preferring to nest higher off the ground. Once a wasp colony decides to construct their nest on your property, you have a wasp infestation on your hands.
They build paper nests from wood pulp, which they manufacture by chewing wood fibres and mixing them with saliva. The Queen wasp will start a new nest every year. Queen wasps hibernate during the winter, then emerge in April to find a new nesting site. Worker wasps normally do not survive the cold winter temperatures.
The Queen is the only wasp who is able to lay eggs, and rears broods of worker wasps throughout the summer. Generally, there will be 3,000 – 5,000 wasps in a colony, but they can grow up to 10,000. Wasp nests are greyish or straw-coloured and grow to around the size of a football.
