Spider mites are members of the Acari (mite) family Tetranychidae, which includes about 1,200 species.[1] They generally live on the under sides of leaves of plants, where they may spin protective silk webs, and they can cause damage by puncturing the plant cells to feed.[2] Spider mites are known to feed on several hundred species of plant.

[edit] Description
Spider mites are less than 1 millimetre (0.04 in) in size and vary in colour. They lay small, spherical, initially transparent eggs and many species spin silk webbing to help protect the colony from predators; they get the 'spider' part of their common name from this webbing.[2]
[edit] Life cycle

Hot, dry conditions are often associated with population build-up of spider mites. Under optimal conditions (approximately 80 °F or 27 °C), the two-spotted spider mite can hatch in as little as 3 days, and become sexually mature in as little as 5 days. One female can lay up to 20 eggs per day and can live for 2 to 4 weeks, laying hundreds of eggs. A single mature female can spawn a population of a million mites in a month or less. This accelerated reproductive rate allows spider mite populations to adapt quickly to resist pesticides, so chemical control methods can become somewhat ineffectual when the same pesticide is used over a prolonged period.[3]
Spider mites, like hymenopterans and some homopterous insects, are arrhenotochous: females are diploid and males are haploid.[4] When mated, females avoid the fecundation of some eggs to produce males. Fertilized eggs produce diploid females. Unmated, unfertilized females still lay eggs, that originate exclusively haploid males.
[edit] Genera
The best known member of the group is Tetranychus urticae, which has a cosmopolitan distribution,[5] and attacks a wide range of plants, including peppers, tomatoes, potatoes, beans, corn, Marijuana, strawberries.[3] Other species which can be important pests of commercial plants include Panonychus ulmi (fruit tree red spider mite) and Panonychus citri (citrus red mite).
The family is divided into the following subfamilies, tribes and genera:[6]

Yeah I got a mite problem at the worst time. At any rate I probably will just go ask the guy at the local grow shop as he knows his stuff and it is just down the road tomorrow. Wanted to get informed before hand with options and questions in my mind before I go to the store tomorrow.
