The Q&A Archives: Neem oil

Question: What is Neem oil? Are there any downsides? Does Home Depot carry it?

Answer: Neem oil is a vegetable oil pressed from the fruits and seeds of Neem (Azadirachta indica), an evergreen tree which grows in the tropics. Formulations made of Neem oil find wide usage as a bio-pesticide for organic farming, as it repels a wide variety of pests including the mealy bug, beet armyworm, aphids, the cabbage worm, nematodes and the Japanese beetle. Neem Oil is not known to be harmful to mammals, birds or some beneficial insects such as honeybees and ladybugs. 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 oil also controls black spot, powdery mildew, anthracnose and rust (fungus).

Home Depot carries products containing Neem Oil. It is also available online.
