First, read the English article below.

Add 1-2 cups of rolled or steel-cut oats to a warm bath, and soak in the tub for at least 15 minutes. The oats may help soothe the itching and reduce inflammation. After brushing off the ants, immediately rinse the area with rubbing alcohol and leave it wet. Note, though, that alcohol could also make the ant bite worse. Elevate the area and sprinkle a generous amount of meat tenderizer on the area. Golfers sometimes use this method in Florida.  Keep a bottle of liquid hand sanitizer handy in your bag. Apply the hand sanitizer to the bite area liberally after freeing your skin of ants. Let it stay in place. Take Benadryl or equivalent antihistamine when you get back home. This may help lessen the itching and can help to reduce redness. A paste made from baking soda and vinegar may also work. As may vinegar on its own. [citation needed] As soon as you are stung, use ammonia to rinse the area as quickly as possible. This may help minimize the effects of the stings.
