My outdoor containers have millions of microscopic flies...

...on the soil surface. I suspect that the compost/mulch is to blame. My plants are fine, but I want to plant more seeds for another crop and I worry that the flies will eat the seedlings.

Does anyone have a solution to getting rid of the flies and their larvae?

RE: My outdoor containers have millions of microscopic flies...

They are most likely to be fungus gnats. The best and safest way to get rid of them is with BT, a bacteria and one of the oldest organic pesticides. You can buy mosquito dunks and dissolve a small amount in water, then drench the soil. It kills the larva.

Fungus gnats are definitely a sign that your potting mix is too water retentive.
