Identifying: Mites are not insects but are more closely related to spiders. Since they are extremely small, plant damage is typically the first sign of their presence. A silky web is often seen with heavier infestations.
Damage: Both spider mite adults and their immature forms damage plants by sucking plant sap. Damage includes light-colored speckling on the upper surface of leaves and results in a plant with an overall faded look. If the mites are left unchecked, leaves become bronzed or yellowed and the plant dies. Spider mites are usually more of a problem on house plants that remain indoors year-round.
Control:
Neem oil- The organic compounds in neem oil act as a repellent. Follow package instructions for diluting the oil in water and spray affected areas. It is often necessary to spray once a week for several weeks to control mites.
Discarding the plants- With a heavy infestation, it may be necessary to discard the plant, disinfecting the garden. Wait for 1-2 weeks before plugging new soils in to avoid continuing the life cycle.
