Tiny flies in bathroom

Hi EF,

Since the last few weeks, some tiny flies started to show up in my bathroom. They are very tiny. I have no clues what they are exactly. I suppose they cause no harm, but I think it would be great to get rid of them. Anyone knows what they are, and how best to keep them away? Thank you!

they look like fruit flies

Time flies like an arrow. Fruit flies like a banana.

You have to get rid of their food source. That can be fruit (why would you have fruit in the bathroom), but it can also be the gunge in the drain pipes. You could try sending bleach or boiling water down there.

They like to breed in the drain lock.
