Cynoff EC is an emulsifiable concentrate insecticide intended for use by professional pest control operators. Its active ingredient is Cypermethrin (24.8% by weight), which is a synthetic pyrethroid. This product is designed to control a wide variety of pests, including ants, fleas, cockroaches, spiders, wasps, bed bugs, mosquitoes, and various other crawling and flying insects. It can be applied both indoors and outdoors. Indoor applications include treating cracks, crevices, baseboards, and window/door frames, while outdoor applications involve treating cracks, crevices, eaves, and vegetation. When used indoors, it should be applied to specific target areas rather than as a space spray. For outdoor use, it is limited to crack-and-crevice treatments and certain vegetation applications. Always follow specific dilution rates: 0.1% for certain pests like ants and fleas, and 0.2% for bees and cockroaches. Users must wear appropriate Personal Protective Equipment (PPE), including long-sleeved shirts, long pants, shoes, socks, and chemical-resistant gloves when using handheld nozzles. Avoid contact with skin, eyes, or clothing, and do not breathe vapors or spray mist. The product is highly toxic to fish and aquatic invertebrates; avoid runoff into drains or water bodies. Re-entry interval (REI) is not explicitly listed in the provided text, but users should follow all precautionary statements regarding occupant safety.
