Tiny hoppy flies that crawl out of the shower drain?

[critterz]

Anyone else get tiny little flies crawling out of their shower drain? They have wings, but if you try to squish them they hop. My photo isn't great as they're so tiny.

Drain flies

Definitely drain flies.
Pour Mr Muscle Drain Unblocker down the drain and put a plug in the drain if you have one. In the morning pour a kettle of boiling water down the drain.
Do that for several days, and they'll be gone.
