A small, soft-bodied pest that feeds on plant sap, reproduces rapidly, and can spread plant disease while weakening leaves, stems, and new growth.
Aphids gather in clusters on young stems, buds, and the undersides of leaves, where they feed by piercing plant tissue and removing sap. Small populations rarely cause serious harm, but large infestations can stunt growth, curl leaves, distort flower buds, and reduce fruit production.
As aphids feed, they produce a sticky substance called honeydew that coats nearby leaves and often attracts ants. Because aphids reproduce quickly, a minor infestation can become a major problem within a few weeks.
Some aphids also spread plant disease by carrying viruses from one plant to another as they feed.
Aphids are one of the most common garden pests, but they're also one of the easiest to manage when detected early. Regular monitoring helps prevent damage before populations become established. Many gardens naturally control aphids through beneficial insects such as lady beetles, lacewings, and parasitic wasps. Encouraging these natural predators is a key part of biological control and integrated pest management (IPM).
