Although they rarely attack unprovoked wasps and hornets can be dangerous to Humans. Especially if allergic. If a nest is found and it isn't near or in your home, it's best to leave it alone.Wasps/Hornets can be very beneficial if left alone. The entire colony will die during the winter save for the queen.

There are two types of wasps, Solitary and social. Both meaning exactly that. Social wasps congregate and build a nest about the size of a basketball, whereas solitary spend most of their time alone and build small nests with typically one egg.

What are wasps?

  • Wasps are insects with two pairs of wings (unlike flies with just a single pair of wings). They have a constricted waist and an abdomen covered in yellow and black stripes.

    The Common Wasp, Vespula vulgaris, typically nests either underground or in cavities in trees and buildings.
  • The Queen wasp will hibernate during the winter, making a nest in the spring in which to lay her eggs.
  • The Queen will feed the larvae on insects until they develop into worker wasps.
  • After 3-4 weeks, the workers will forage for food outside of the nest.
  • The Queen will continue to produce eggs which the workers will then tend to, with nests producing upwards of 20,000 wasps!

What problems do wasps cause?

  • Wasps become a particular problem in the summer months, when the workers begin to forage for sweet -based foodstuff with which to feed the reared young.
  • As a result wasps will often come into contact with man in urban environments and are known to become annoyed and ‘irritable’ if threatened, resulting in the wasp stinging.
  • Their threat is twofold. Firstly, they can contaminate foodstuffs they come into contact with; and secondly, they have a sting which at best is painful and at worst can cause a violent reaction to the sting resulting in several people a year dying.

How are wasps controlled?

  • Wasps can be controlled by a combination of methods.
  • Wasps can be excluded from an area using insect fly screens.
  • Wasps can be trapped using a bait
  • Wasp nests can be treated using specially labelled insecticidal dusts and sprays
