From what I understand, neem does not kill the larvae of the pests... just the adult versions, so you need to make repeat treatments. And I'm not sure it works on fungus gnats at all (at least it didn't work on mine). I believe the pest has to be sort of "hanging out" on the leaf when you spray/wipe down the leaf with neem, and my gnats certainly didn't just "hang out" on the leaves, waiting to be sprayed.

I did recently buy a Bayer systemic treatment that you can supposedly just water your plants with... it's supposed to work on hundreds of insects, while also feeding your plants. Supposedly it works for 12 months before you need to re-treat. I haven't tried it yet, though... I want to do it outside because I'm pretty sure there's some nasty chemicals in it that I'd rather not risk spilling on my carpet.

But anyway, it IS supposed to kill all bugs that munch on your plants, as well as pests and larvae that lurk in the bark. I'll let you know if I see a difference when I finally use it. I think I'm going to try the stuff I mentioned earlier that's specifically targeted at gnats first, though, since it's non-toxic to people (I think). Apparently it combats the pests by introducing one of their natural enemies into their environment ... it's some sort of larvae I think. But anyway, it's supposed to be fine for us, but terrible for the insects.

I do hope your solution worked, though. I have hundreds of orchids, so unfortunately doing a mass dumping and spraying and drying out is somewhat impractical....

Keep us posted!
