ELI5… How do gnats just… show up?

750 views

I understand what their attracted to. Moisture/fungus etc. But I over watered my plants a couple weeks ago and BAM, gnats. They’re indoor plants so I’m just curious how they showed up/ get in the house? Do they lay dormant or something? Are they in the soil? EXPLAIN, PLEASE. Thank you in advanced.

Edit to include that I live in Canada and it’s winter and cold where I live. Obviously gnats can’t survive outdoors in this weather. Do they find a place to live somewhere in the house and lay dormant until it’s snack time? I just don’t get it. They just seemingly magically appear and I need answers!

fungus gnats. their eggs lay dormant in potting soil. when you water it, thats when they hatch and turn into adults a little later. I sometimes have this problem in Canada, in winter, as well.
