Neem oil is used for preparing cosmetics such as soaps, hair products, body hygiene creams, hand creams. Formulations made of neem oil also find wide usage as a biopesticide for organic farming, as it repels a wide variety of pests including the mealy bug, beet armyworm, aphids, the cabbage worm, thrips, whiteflies, mites, fungus gnats, beetles, moth larvae,mushroom flies, leafminers, caterpillars, locust, nematodes and the Japanese beetle. Neem oil is not known to be harmful to mammals, birds, earthworms or some beneficial insects such as butterflies, honeybees and ladybugs (ladybirds in UK English) if it is not concentrated directly into their area of habitat or on their food source. It can be used as a household pesticide for ant,bedbug, cockroach, housefly, sand fly, snail, termite and mosquitoes both as repellent and larvicide. Neem extracts act as a phagorepellent (antifeedant) and by blocking the action of the insect molting hormone ecdysone. Azadirachtin is the most active of these growth regulators (limonoids), occurring at 0.2–0.4 % in the seeds of the neem tree.
