If they are flowering, don't use these chemical products. Use insecticidal soap. Spray the plants down to wash off many of the mites. The predator mites, insecticidal soaps, and strong spray from the hose sprayer ( not a little hand pump) are the safest way to deal with this at flowering. Neem sprayed on the flowers leaves a bad taste on the buds and the chemical treatments have active ingredients that last for days or weeks and some are systemic and are trans-located to all parts of the plant.. If you have been spraying Neem after releasing the predators you could be killing them too.
