What do flies do on your skin

In: Biology

Flies carry dirt and Bacteria on them and are generally unclean (although, interestingly, they do take time to clean themselves). When they walk on your skin, they leave those harmful bacteria on it, which is normally OK as your body has natural ways of defending itself. However, if you have an opening in your skin, like a cut or piercing, the harmful bacteria can find their way inside and cause problems. However, considering the fact that your skin is always covered in bacteria (helpful and harmful ones), flies aren’t such a big problem
