Stay calm. Stay out of the wasp’s flight path if you possibly can. Everybody has their pet theory about what to do if wasps get angry, some people recommend running like crazy, but you should run with dignity, not slapping yourself. Every person I’ve ever seen stung by a wasp has swatted at them. While it’s an understandable reaction, it’s the worst thing to do. Move away slowly and steadily.
Another option is to freeze. This seems to work well too, as long as you have the self-control to watch a wasp hovering past your eyes, checking you out. You hope they won’t do anything more about it, and almost for sure they won’t.

Be Aware of Changes in Behaviour

When observing a nest, you will normally see a steady flow of wasps flying in and out of the nest. When you notice a few wasps just hovering about, this is a sign they have become suspicious of you or your actions. Immediately stop what you are doing and retreat slowly.

Some park rangers say run, run like hell, but some wasp exterminator says freeze and stay out of the flight path. When they lose interest, walk away quietly.  And if you are in the bush carry antihistamine and a first aid kit with you.

Damn, I’m stung. Now what?

Usually, wasp stings cause only local reactions, but sometimes severe allergic reaction occurs – ring 111 if needed.

▪ If stung on the neck, face or in the mouth, take an antihistamine and see a doctor immediately. Stings can cause swelling in the throat, making it difficult to breathe.
▪ Otherwise, apply an ice pack on the area, or apply antihistamine cream (and take it easyfor the rest of the day.)
