I know there's a name for them - gnats of some type - and I would include a photo if I had a microscopic lens and could get one of them to pose for me, but I don't....

So, I'm talking about these tiny little flies - that really do fly - and kind of buzz around the top of the medium, and, like fruit flies, drop dead all over the shelf on a daily basis. I think I've read that they're not particularly harmful to the plant, but I'm not sure, and I despise them anyway. I have also read, I think, that they lay their eggs in the medium, which is why yellow sticky-paper doesn't get rid of them.

I have insecticided my plants a few times and it gets rid of them for a little while, but they always come back, and I don't want to have to use insecticide every time I water my plants.

By the way, I don't think I'm overwatering - if anything, my plants are drying out so fast I can hardly keep up with them.

Anyone have any solutions or similar experiences?

Thanks.
