Azadirachtin is a compound that is extracted alongside other compounds from the seed kernels, leaves, and barks of the neem tree. The extract is used as an organic insecticide and fungicide owing to its natural ability to kill, harm, and repel some species of insects through various modes of action including feeding inhibition, growth regulation, and sterilization among others. Products containing Azadirachtin are largely considered non-toxic to mammals though potentially toxic to some beneficial insects including bees, ladybugs, and aquatic organisms.
