Wasps Infestation

Wasps are mainly controlled for their nuisance value, although there is some evidence that they may be vectors of disease, caused by their feeding habits in dustbins, waste skips and also on carrion. 
There is no need to discuss the sting of a wasp here, suffice to say it can be extremely painful and prove life-threatening to those susceptible to venom.  Over 50% of people who die from stings/bites by venomous animals are killed by the (not so) humble wasp.

Lifecycle

1. Young Queens overwinter and emerge in the spring to start nest building and lay eggs.
2. Workers (sterile females) emerge during early summer and take over nest building. Queen continues to lay eggs.
3. New queens and males mate in early autumn.
4. Nest dies during winter, including all the males and workers. Only Queens survive to the next year.
