Red fire ant bites result in rapid redness and swelling of the wound with a hot, painful sensation, and small red dots. You can flush with running water and apply cold compresses to relieve the pain, and you will recover in a few days. The venom of bees is acidic, and after being stung, the poisonous needle will be pulled out and can be flushed with ammonia, soapy water and other alkaline liquids to neutralize the toxicity. If you are bitten by a centipede, you can first rinse with soapy water, baking soda and other alkaline liquids, then use cupping or other items to suck out the venom, and then go to the hospital for examination.
