Wasps are frequent uninvited guests on terraces and at barbecues. People often resort to chemical products or homemade solutions, such as burning coffee grounds, to deter them. However, once a wasp stings, pain and other symptoms can follow.

A recent example from the RTL office in Kirchberg illustrates a common scenario. A colleague walked through the newsroom with a severely swollen hand wrapped in gauze. He had been cleaning his home's gutter, unaware that wasps had nested in the leaves. They stung him in defence. Fortunately, he required only a brief trip to the pharmacy.

More critical cases occur when individuals are allergic to wasp stings, which can quickly become life-threatening. Guido Genten, a nurse with Air Rescue, notes that their team is deployed on average once or twice a week during the summer for such emergencies.

According to Genten, an early sign of a severe reaction is difficulty swallowing, which can indicate swelling in the oral cavity. This swelling can affect the airways, potentially leading to a life-threatening condition or cardiovascular problems.

Many people are unaware they are allergic to wasp stings, and allergies can develop with age. If symptoms extend beyond normal swelling and pain, it is crucial to contact emergency services by dialling 112.

Once contacted, emergency services assess which rescue unit is closest. Sometimes the Emergency Medical Assistance Service (SAMU) is despatched, but if a helicopter is the fastest option, it will be deployed, Genten explains.

Typically, a wasp sting is not particularly dangerous. While painful, most people can manage with a cold compress, an ice cube, and possibly some ointment.
