Hmm... so maybe I've never noticed any harm, because I don't grow pygmy
drosera. That would explain. Even my VFT-seedlings never showed problems,
but I wouldn't claim, the fungus gnats cannot harm the plants.

I think so too (eggs in the compost, not for your wife...) - but since the
gnats are flying (rather running...) around everywhere once you have one
infected pot, who knows. But microwaving the compost: Now THAT's a
brilliant idea! That may also kill other pest squating in there.

Take care,
