Aphids are small-scale, soft-bodied insects that pull sap. They can cause stunted growth, yellowing leaves, and distorted flowers. Neem oil works by disrupting the hormone system of aphids, causing them to stop feeding and eventually die.

Whiteflies are tiny, winged creatures that gather on the bottom of leaves. They feed by sucking the sap out of plants, which can cause yellowing leaves and stunted growth. Neem oil works by suffocating whiteflies and preventing them from laying eggs.
