Common Houseplant Pests and Their Signs
The best protection for your plants is early identification of pests. Here are the usual suspects and what to look for:
Aphids
These soft-bodied insects congregate on new leaves or under leaf surfaces. They suck plant sap, causing yellow or deformed leaves and stunted growth. Over time, their secretions can lead to mold, further damaging your plants.
Spider Mites
Tiny insects that weave webs on plants and prefer dry conditions. They cause yellowing, which then causes leaves to dry up and fall off. They can quickly build up in population, so catching them early is paramount.
Fungus Gnats
Small flying insects that resemble mosquitoes. Adults are merely annoying; the larvae feed on plant roots, causing wilting and stunted growth. The most common issues arise in overwatered or poorly drained soils.
Mealybugs
White, cottony masses on joints of leaves. They cause yellowing, wilting, and sticky leaves by sucking sap. Heavy infestation often weakens plants.
Scale Insects
Hard-shelled pests that attach themselves to stems and leaves to suck sap and excrete a sticky honeydew-attracting mold. Often not readily noticed since they resemble a shell.
Thrips
Small, elongated insects with a sucking mouthpart; scrape the leaf surface and cause silvery or speckled discoloration, often damaging tender new growth. A little early recognition will save you from their spread.
