Moth Fly

6209  Hello, I live in Burlington Ontario. We have those flying insects, they look like flies but shorter with more round wings, they fly very quietly so they are not annoying like flies or mosquitoes but they started to get everywhere, we found them inside the coffee machine in couple of cases. Are they harmful? Where did they come from? How to stop them? From Burlinton, Ontario

Their larvae usually are found in small accumulations of very foul water, such as in seldom used floor drains or drip trays under refrigerators.
