There are many species of spider mites (around 1,200 species) all belonging to the family Tetranychidae. They generally prefer living in the undersides of leaves, where they spin protective silk webs which are also used as a means to protect their colonies as well as to travel from plant to plant. Spider mites can be difficult to spot but if unchecked, later move to the upper leaves. Spider mites vary in color, thus scouting and identification are key.

There are specific natural enemies for different species of mites.
