The name says a lot about these pests. Tiny, moth-like insects, whiteflies have heart-shaped bodies and are about 1/10 inch long. White in colour, you might not notice them until you move your plant. The adults will fly around once disturbed. If you see other white bugs that don’t fly, they’re likely mealy bugs.
Whiteflies suck juices from leaves and flower buds of plants. Eventually, they turn yellow and drop from the plant. They do this at nearly every stage of their life, from nymph to adult. Without treatment, this can cause major damage to a plant and even kill it.
