How to treat wasp stings explained
WASPS are invading picnics and homes as the summer heat brings the queens out of hibernation and they start to colonise.
But what should you do if you get stung this summer?
Why do wasps sting?
Wasps sting when they feel threatened as a way of fending off what they believe to be an imminent attack.
Like bees, it is only the female that can sting but, unlike bees, they are able to attack victims more than once.
Experts say that wasps will not sting someone if they are at rest, and the chance of being stung is higher if you threaten their nest or try to swat them away.
The stings are packed with venom meaning humans find them painful and some can suffer life-threatening allergic reactions to them.
How do I treat a wasp sting?
If you are unlucky enough to be stung by a wasp it is important you remove it as soon as possible.
The sting can be scraped away from the skin using the edge of a credit card, or if you don't have one to hand, you can use your fingernails.
You should never use your fingers or tweezers as it can cause the venom to spread.
After removing the sting you should:
- Wash the affected area with soap and water
- Apply ice or a cold compress for up to 10 minutes to reduce the swelling
- Avoid scratching the area to reduce the risk of infection
- Not apply home remedies such as vinegar or bicarbonate of soda, as they're unlikely to help.
Some people are allergic to wasp stings and they can cause them to go into anaphylactic shock, which requires urgent medical treatment.
Symptoms of anaphylaxis include:
- Severe swelling
- Hives or itching
- Dizziness
- Nausea and vomiting
- Stomach cramps
- A sudden drop in blood pressure
