Can flies bite hamsters?

First of all, flies are just smelly things, they don't bite people, they just eat some rotten things, so don't worry about flies biting hamsters.

Obviously, flies rarely meet hamsters, so in fact, flies pose no threat to hamsters. If there is anything wrong, assuming that hamsters have too much feces and urine, it may attract flies and bring germs, which may pose a threat to hamsters, but this is already a very dirty situation.
