2017 could be the worst wasp summer for a long time! Due to the warm spring, the buzzing mourners have been traveling much earlier - and they could spread rapidly, experts warn.

Means for us: For our barbecues or our extensive sessions on the sun lounger we need this year probably strong nerves and patience. And of course self-restraint - because when the striped critters swarm our ears, we could go up the walls regularly.

In such situations, many try to scare away the wasps and waving wildly with their arms and hands. However, this is the wrong reaction, because these wild movements make the animals aggressive. So it can happen that wasps, which actually have no interest in us humans, attack suddenly and sting us.

Blowing is also a bad idea: the air in our breath contains carbon dioxide that sets wasps in alarm. So best: sitting still or lying still - even if it is difficult?
