Wasps are seasonal pests, emerging in Spring until the cold months, when the Queen hibernates and the workers die off.
They become a pest after making a nest in our roof spaces, cavity walls or nearby trees.
Wasps will sting without provocation. Stings can be painful but aren’t dangerous unless you are in the 1% of the uk population that has an allergic reaction to the sting. In which case, urgent medical attention must be sought.
