Patients who are inadvertently bitten by fire ants can often take different clinical treatments according to the severity and scope of the bite: 1. If the patient is bitten by fire ants to a lesser extent, the local injury is more limited and does not cause extensive infection.

Most of the patients after 3-5 days of local treatment, the swelling symptoms can subside on their own, playing a better therapeutic effect. 2, if the patient is bitten by fire ants is extensive, the damage is more serious, the local swelling, pain, skin temperature increases, activity is limited.
