Houseplant pests include those that attack house plants by chewing and sucking as well as those that are considered pests by their mere presence. Pests that suck plant juices usually are the most damaging.
Mite injury is first visible as light speckled areas on leaf surfaces.
Later the leaves bronze or yellow, and may die or drop. Heavily infested plants become stunted or die. Flowers may be faded. Thrips are not truly sucking insects as they feed by rasping open leaf tissues before sucking up the liquid contents. There are usually both winged and wingless forms.
