Signs and symptoms of aphids on indoor plants

  • 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 and the area around the plant sticky and supports the growth of sooty mold.

Management strategies

  • Aphids can be washed off the plants with water.

  • If necessary, aphids may be controlled with an application of insecticidal soap labeled for indoor plants or a houseplant insecticide.

  • Check the label to make sure it is safe to use on the plant and pest.
