A vegetable oil pressed from the fruits and seeds of the neem tree, neem oil is a natural pesticide, insect repellent and medicinal herb that has a bitter taste and garlic odor. It’s practically non-toxic to birds, mammals, bees and plants.
This broad spectrum bug killer can be used on virtually any sort of garden creepy-crawlie – it’s known to be effective against over 200 species of chewing or sucking insects! It also fights fungi, mildews and rusts.
Neem oil spray is most useful when applied to young plants where it can act for up to 22 days. However, rain will wash the oil away, rendering it ineffective.
