If you are bitten by black ants, you may be stimulated by the substances secreted by the ants and cause an allergic reaction to the skin. Generally, the main substance on the ants’ teeth is ant acid, so you can use alkaline cleaning agents to clean them, for example, you can rinse them with soap and water to help remove the ant acid. If you have a sensitive body, you may have obvious allergic symptoms, such as hives and itching, which need to be treated with anti-allergy medication, such as topical cycloheximide cream or oral loratadine. You can also take oral calcium gluconate or vitamin C to help reduce the permeability of blood vessels and relieve the symptoms of allergy. For severe symptoms, attention should also be paid to timely disinfection with iodophor to prevent infection.
