    If anyone ever tells you that fungus gants won't hurt your plants, they are wrong. I have caught a few larvae red handed working their way through my utric pots. I'm going to try the Bt strain (Bti or Bt H/14) designed to kill them. Has anyone tried this? The products I've seen are called "Gnatrol" and "Knock-out Gnats".

    well, fungus nat larvae won't hurt them that's the best food source for them. they might hurt flytraps. if you don't want them, transplant a sundew in all of your utric pots and that should do it...

    I wouldn't argue with Dodec. If he says that his plants (95% of which are Utrics) are being eaten by gnat larvae then in all probability his plants arebeing eaten by gnat larvae

    Spec, I realize that the conventional wisdom is that they don't harm plants, but I've seen it with my own eyes! It was crawling across the surface of a pot of U. blanchetii mowing down the leaves. I also have suspicious little dead spots in a few other pots. Anyway, the flies are pretty annoying too.

    the safest and fastest and best way to get rid of them is to flood your utrics in buckets for a couple of days.







    I now believe you that they would harm the plants. they could eat all of the stolons! [img]http://www.**********.com/iB_html/non-cgi/emoticons/wow.gif[/img] I'd get rid of them fast!

    Flooding doesn't help, the little buggers seem to do best in Utric pots which I know Dodec has on a flood and dry cycle. I think the BT treatment might work, maybe predatory nematodes as an alternative [img]http://www.**********.com/iB_html/non-cgi/emoticons/confused.gif[/img]

    Fungus gnat larvae do feed on roots and can cause root rot and plant decline.

    Careful where you crawl, it might be a trap!
