OK, maybe you should read this. About half way down I go into some detail about spider mites. It may answer some questions in this thread. There are pictures and links.

Other than pesticides, there is really only one thing that works well, and that is preditor mites. They are expensive. Use at least double the recommended dose. And by "works well", I mean for good. The "no more applications needed" kind of "works well". Anything else may work, but as far as I know, not for good.

Real simple:

In order of preference, with most prefered at the top.
unsafe and effective:
- No Pest strips
- Avid
- Perithium boms
safe and effective:
- preditor mites
- other preditors

ALL ELSE SHALL FAIL TO COMPLETELY RID YOUR GROW OF MITES IN ONE TRY AND FOR GOOD!

Good Lord, looking back I can't believe all the hours I wasted fiddling around with neem oil. The first couple of times I was so dissapointed after a few days of the treatment. I thought they were gone from the neem oil, but it only brought them back more resistant to neem oil, and madder than hell at me. They all banded together and were determined to really screw me over even more this time.
