best stuff to get rid of mites is pure spray green. It will get rid of them in 2 applications. Just spray underside of leaves. 10-20 min before they go to sleep. Then re-apply in 3 days. It kills adults, babies, and eggs. Its organic and omri listed. Its very concentrate. It will last a very long time. Its around $17 for a quart. Mixes with water. you can sleep right next to the plants after using it and it wont effect you. Neem oil works too, but its in inhibitor though. So doesn't always work
I've tried everything. This stuff is the best. Ive been using it fo 4 years. I have not had mites in at least 2 years. Now I use it to kill gnats when they become immune to neem. Gotta switch it up sometimes.
