Never touch, catch or tease a wild animal, even a small one, and even if it looks asleep or dead.
Give it space. If you meet one, stay calm, step back slowly and let it go its own way.
If one bites or stings you: stay calm, keep still, call your emergency number (112, 000, 911) or get to a hospital fast. Remember what it looked like, a photo helps.

It is not out to get you. It uses its venom to catch food or to protect itself, and it would much rather hide. More about staying safe
