Problems with mite injury are most common on hot, dry, dusty sites. In addition' dusty conditions inhibit the effectiveness of natural enemies of spider mites, which are not as well adapted to these harsh circumstances. Though small and inconspicuous, they are an important component of spider mite control. Spider mite destroyers feed only on spider mites. There are predatory mites that feed on mites.
Phytosiied mites are shiny, oval to pear-shaped and move much faster than spider mites.
They also eat other plant damaging mites, as well as scale insects, whiteflies, thrips, and some insect eggs. Although natural enemies of spider mites are available commercially, it is more efficient to conserve resident natural enemies in the landscape and garden by controlling dust, avoiding pesticide applications and supplying plants with adequate irrigation. One cause of mite outbreaks in yards and gardens is the use of insecticides that destroy spider mite predators. Outbreaks occur when pesticides eliminate natural enemies, allowing mite populations to grow unchecked. This allows surviving natural enemies to migrate in from the adjacent unsprayed areas.
