As stated previously, neem is the way to go for pest issues. I have always used Azatrol with great results. Works for soil pests (in my case some annoying root aphids) as a drench and can be used as a dunk for clones. It can also be sprayed for established plants. BUT, if you already have flowers, I do not recommend spraying. Even though it is natural, neem had a smell and taste that I would not want to smoke.
Also, clean everything and figure out how they got into your grow. This is assuming that you have mites.
