Experts are predicting huge increases in wasp populations this year with the early start to the warm weather.
Queen wasps have been especially active and larger than average nests are expected.
In the past month, pest controllers have seen a fourfold increase in the number of calls from people to get rid of wasps.
By August, huge nests containing up to 6,000 wasps each will be turning up in roofs and garages, Rentokil predicts.
Rentokil said: "Wasps are out early and in large numbers. By starting earlier, they have the opportunity to create larger nests, with larger populations."
Just days ago wildlife experts said the early sunny weather had sparked a population explosion among ants, which have an abundance of food.
