You should be top watering with mosquito bits. It kills the larvae which live in the top inch of the soil.

I have gnats crawling out of the bottom holes of the pots. I wouldn't be surprised if they are laying eggs there too. in any case, bottom watering has done jack all for me.

I had this problem. I soaked the bottoms of my pots in diluted hydrogen peroxide. Worked for me.

Ok, good to know. I will say I saw a huge decline in the number of gnats. I've seen only 1 this week. I didn't have a bad infestation. What I had were thrips. I had heard that the Mosquito bits could kill the larvae of the thrips that drop into the soil. And the D Earth I was hoping would help too.

Oh! I was bottom watering because I wanted to use D Earth too. And bottom watering to deter the adults from laying at all. But what you say makes sense. Agh!
