Wasps and bees have stingers that deliver venom and cause pain when injected into the skin. Honeybees sting once and leave a stinger in the wound while wasps and hornets  can sting many times. Most people who are stung by an insect will have redness, itching, swelling, and some pain around the sting site.  Some people are allergic to insect stings. They may experience rashes, itch, headache, dizziness, nausea, vomiting, puffiness of the eyes, lips, tongue and throat, and difficulty in breathing. Symptoms can begin immediately after the sting or up to 30 minutes later and might last for hours. The patient can die of shock if this response is not reversed within a short time. Non-allergic victims who receive multiple stings can also develop serious complications. First aid for wasps and bees stings Scrape out the stinger with a stiff object like a credit card. Do not touch the stinger or pull it out yourself as this would inject more venom into the wound. Remove any rings and watches before any swelling occurs. Wash the sting site with soap and water. Wrap a few ice cubes in a towel and apply on the area for 10-15 minutes to stop the pain and swelling. To prevent frostbite, do not apply ice directly on the sting area.
