There are over 7,000 species of wasps in the UK. They are considered to be pests to many since they often live in manmade structured and can provide painful stings if one gets too close. Wasp nests tend to appear in the spring and become more common during the summer months.
Wasps will usually only attack a person if they feel threatened. The problem is a social wasp in distress emits a pheromone that sends nearby colony members into a defensive, stinging frenzy.
If you’re sensitive to wasp stings then they can send you into anaphylaxis - a severe, potentially life-threatening allergic reaction.
