Simple remedies for wasp stings – try these for yourself
What can you do if you’re stung by a wasp? Allergic reactions should be reported to a doctor immediately. "Normal" ones can be treated with simple household remedies.

Wasps like to gatecrash any garden party. The sting of these uninvited guests hurts and can last for several days. It can help to either cool the sting or place a hot cloth or spoon on it (be careful of burns!). Heat destroys the protein in the venom and reduces the itching and inflammation.
Better safe than sorry
Rubbing half an onion on the sting also helps to reduce the swelling. Better still, take precautions to drive wasps away before they sting! A table decoration made from lavender, carnations and citrus fruits is a great deterrent to these pesky insects. An attraction station with ripe grapes, honey and jam also keeps the insects at bay. Important: Place food and drinks on the table in sealable containers and always check them before every sip or bite!
Dr Paola Maltagliati-Holzner, a dermatologist with Medgate:
“If you’re stung in the mouth or throat, you should see a doctor immediately. Rapid medical treatment is required as it poses a risk of suffocation. You should also see a doctor straight away if you’re allergic to wasp stings, if you experience a reaction in places other than the sting site, or if you experience other symptoms (e.g. a rash; itchy palms, mouth or soles of the feet; difficulty breathing; or dizziness).
