How to Treat and Prevent Aphids in Houseplants

Aphids are small, soft-bodied insects that can be a major nuisance for houseplant owners. They can quickly infest plants, sucking the sap from leaves and stems, so it’s imperative that you learn how to treat and prevent aphids. This can weaken the plant and make it more susceptible to disease. Aphids can also be a nuisance because they produce a sticky substance called honeydew. Honeydew can attract ants and other pests, and it can also stain furniture and other surfaces.
