Definition - What does Spider Mite mean?
Spider mites are a garden pest of the Acari or mite family of insects that live and feed on the bottom side of a leaf on a plant.
Because they spin a powdery white web, spider mites are sometimes confused with another plant condition called powdery mildew.
MaximumYield explains Spider Mite
Spider mites are leaf suckers and chewers that can deprive the leaf and plant of nutrients. If left untreated, a spider mite infestation can and will eventually weaken and kill the plant.
They are a common problem for commercial greenhouses and florists, as they can infest nearly any type of plant.
Spider mite infestations normally occur either during or just following a warm dry spell. The two-spotted spider mite can hatch in just three days and mature in fewer than five. Once an infestation is noticed, it can soon spread throughout the entire garden.
Spider mites are most recognized for their white, soft web they spin on the bottom of a leaf. It is only upon closer inspection that they can be identified and treated as a mite and not powdery mildew.
There are many treatments the home gardener uses to reduce or eliminate a spider mite infestation. They range from something as simple as repeatedly washing the infested area of the plant with a mild soapy solution, to utilizing a commercial spray at the agribusiness level.
