Aphids - Houseplants

Back to Common Problems - Houseplants

Aphids are small, soft-bodied insects, of various colors, some may be covered with fluffy white wax. They have long, slender mouthparts, which they use to suck out plant fluids. This feeding causes curling and wilting of the leaves. They may also feed on flowers. They excrete honeydew, which makes the leaves sticky and supports the growth of sooty mold.

Management: Aphids can be washed off the plants with water. If necessary, aphids may be controlled with an application of insecticidal soap for houseplants or a houseplant insecticide. Check the label to make sure it is safe to use on the plant and pest.
