MR 24/7 MR 24/7 works by providing a barrier which is harmless to the plant, but fatal to the mites. Some of the components of MR 24/7 are also absorbed by the plant and then suppress the life cycle of the mites. MR 24/7 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. Use: Spray generously to the underside and top of the leaves. Repeat 3 to 4 days later to ensure any eggs that survived and hatched are treated before they themselves lay more eggs. Box Qty. Wholesale Retail Cat
