This naturally occurring bug killer comes from the seeds of the neem tree, Azadirachta indica. “I use neem oil primarily as a foliar (leaf) spray in the garden, to keep pests like aphids at bay. It’s also great for helping keep powdery mildew under control,” says Bordessa.
Azadirachtin, the primary lively ingredient in neem oil, is poisonous to some bugs. Once they eat it, it disrupts their hormones, makes it tougher for them to put new eggs, and suppresses their urge for food till they ultimately starve. You can both spray it in your vegetation as a safety measure or apply it the place you see small, soft-bodied bugs.
