Why red ant's bite is so hurting and why the bite makes bloated?

Answer 1

Red ants are also called fire ants.Most often the ants have been crawling on you for 10 seconds or more before they grab the skin with their mandibles, double over their abdomens, and inject their stingers, containing a toxic alkaloid venom. A single fireant can bite and sting its victim repeatedly and will continue to do so even after their venom sac is empty. The stings often leave a burning and itching sensation, usually followed by the formation of a white pustule. There will not always be a white postule. The bites may take up to several weeks to disappear. The blisters become itchy and are prone to infection if they are broken. So try real hard not to scratch them open. If they are not properly cleaned or treated, they may cause an infection or leave permanent scarring.
