|Mite-Rid works by providing a barrier which is harmless to the plant, but fatal to the mites. Some of the components of Mite-Rid are also absorbed by the plant and then suppress the life cycle of the mites. Mite-Rid uses a unique formula of botanical oils, including neem, garlic, eucalyptus plus surfactants to provide a protective barrier against many leaf eating pests, and most effectively, the Spider Mite. The main active ingredient from neem oil is a limonoid called azadirachtin which has the steroids campesterol, beta-sitosterol, and stigmasterol. These interrupt the normal hormonal balance of mites, suppressing their reproductive cycle.
