Ants attracted to women’s underwear may be caused by factors such as underwear not being washed in a timely manner, or underwear containing sugar-containing urine. 1. Panties not washed in time: women’s panties may contain secretions such as leukorrhea, which contains shed epithelial cells and proteinaceous substances, or panties with a bad odor, which may attract ants. 2. Sugar-containing urine in panties: There may be urine on the panties, and ants will be attracted to the panties if there is a high level of glucose in the urine. In daily life, women should wash and change their panties in time to keep them clean, which can help avoid the occurrence of gynecological diseases; if the phenomenon of panties attracting ants is accompanied by other uncomfortable symptoms, they should go to the hospital in time to find out the cause of the disease.
