Neem Oil has been used for centuries and is derived from the bark, berries and leaves of the ancient Neem tree. Neem oil eradicates a huge range of fungacides and kills and repels a wide variety of insects and bugs including Spider Mite, Whitefly, Aphids, Stinkbugs and Mealy Bugs. Neem will stop most species of insects, and interrupt the reproductive cycles of bugs that suck the moisture from the leaves or eat the leaves and flowers. Designed for use on fruit, vegetables and ornamentals, the Neem Oil Concentrate should be applied at 5 - 10ml per Litre and works in all substrates and media.
