When ants bite the skin, they will secrete formic acid, which is corrosive and may cause blisters, redness, swelling, pain and other symptoms after contact with human skin, and the blisters will flow after rupture; in addition, when there is a localized skin infection, the skin may also break down and flow.
1. Ants have formic acid in their bodies, which is toxic, and symptoms such as blisters, redness and swelling may occur after skin contact with formic acid. However, general ants have low content of formic acid, and after being bitten by ants, they usually only show symptoms such as itching and red pimples; after being bitten by ants such as red fire ants, blisters are more likely to appear, and water will flow after the skin breaks down, and even symptoms of toxicity such as anaphylactic shock will appear.
2. If you are bitten by ants, repeatedly scratching the lesion area due to itching may cause local skin to be scratched and bleeding, scabs or secondary infection, and pus, ulceration, running water may also occur, and sometimes eczema can also be caused.
It is recommended that patients after being bitten by ants to avoid scratching the local, can use soap and water, baking soda and other weak alkaline solution to wash the wound, if itching, redness, swelling, blisters and other symptoms do not get better, or when the symptoms are serious, you need to consult a doctor in a timely manner, under the guidance of the doctor to standardize the treatment, so as not to delay the condition.
