Dimethoate was reported to be useful in Malaysia and India. Usually, mites are cotrolled by coccinellid predators and predatory mites. In a glasshouse situation, a predatory mite, Phytoseiulus persimilis, has been very successfully used in controling spider mites in the Netherlands and other countries. It is available as a commercial products by Koppert BV, a Dutch company specialized in biocontrol.

Red spider mite and broad mite are major pest in the Northern Marianas islands. The best way to control them is to mix 2 tablespoons malathion, 2 tablespoons dishwashing soap and 2 tablespoons cooking vegetable oil in 1 gallon of water. Apply in the evening, once a week.

For biological control options, try the predatory mite Amblysueis (Neoseiulus) californicus, which can be effective against both the spider mites and the broad mite. This predatory mite is commercially available from many biocontrol companies.
