Erythromycin ointment cannot remove mites. Erythromycin is an antibacterial drug that is mainly used for infections caused by Gram-positive cocci, like Staphylococcus aureus, which are common on the skin surface. So erythromycin ointment is generally used for secondary infections caused by infections or ulcerated surfaces on the skin surface and can also be used to treat acne. However, mites are a parasite and erythromycin has no effect or no effect on this mite. The treatment of mites will generally choose metronidazole, which is anti-protozoal and can treat various worm infections, such as metronidazole gel, and if topical application is not sensitive enough you can also take oral metronidazole tablets. However, erythromycin ointment is only anti-bacterial and limited to infections caused by sensitive gram-positive cocci, so erythromycin ointment cannot remove mites.
