The two-spotted spider mite (Tetranychus urticae) multiplies particularly fast in warm and dry surroundings.
Drip-feed fertiliser/irrigation systems and computer climate control produce a dry environment ideal for its development.
They make a network of webs beneath which they prick the plant and lay their eggs.
Chemical control for thrips is suitable for spider mites also, but if it is used intensively then resistance may appear.
Nowadays biological methods of control appear to be an alternative to chemicals that is well worth considering.
