What are the pests on plant leaves?
Most houseplant pests are small insects or mites that spend most of their time on the undersides of the leaves. These include aphids, whiteflies, mealybugs, scales, thrips, spider mites, and broad mites. Heavy infestations of any of these pests can cause houseplants to be unsightly and undesirable. Symptoms include small white or brown mites crawling across the surface of your houseplant’s dirt. Soil mites are often present in continually moist compost or when situated in darker areas of the house with little natural light.
