Bee/Wasp/Hornet Stings
Look carefully in the affected area and see if the stinger is still in the bite. Use tweezers or a fingernail to remove it. Be careful not to pinch the stinger because it may still be capable of injecting more venom into the bite.
Use ice on the affected area, putting a towel between the ice and the bite to protect skin. Elevate arms or legs if they were the sting areas, and make sure you remove any jewelry, like rings, that might be hard to remove if the area swells.
Pain can be controlled with any over-the-counter medication like ibuprofen or acetaminophen. Use an antihistamine for itchy conditions or apply calamine lotion or a solution of baking soda and water.
The symptoms should abate within two to five days of treatment following the incident.
Fire Ants
Those who encounter fire ants usually receive multiple bites when their mounds are disturbed. The result is boil-like blisters that can sometimes fester into a secondary infection.
Wash the affected areas with plain soap and water, and then ice it to reduce the potential for swelling and ease any pain. Topical treatments include steroid creams to ease itches and pain. The bites should go away in about a week.
