Biology
Boxwood mites are small and greenish brown. Their presence is typically indicated by small white, yellow, or bronze streaks resembling fine scratches or speckles on the upper surface of leaves. The mites may be found on the upper or lower surface of leaves. Heavy infestations may result in premature leaf drop. Mite infestations are often worse during dry, dusty conditions.
Management Options
Use Integrated Pest Management (IPM) for successful plant problem management.
Non-chemical Management
Select non-chemical management options as your first choice!
- Conserve natural predators such as ladybird beetles, lacewings, and predaceous mites. Avoid use of broad-spectrum insecticides which kill these beneficials.
- Wash mites from foliage with a strong stream of water.
- Maintain plant health. Healthy plants are more tolerant of insect and mite damage.
- High levels of nitrogen in the foliage encourage mite reproduction. Switch to a slow-release or low-nitrogen fertilizer.
Chemical Management
IMPORTANT: Visit Home and Garden Fact Sheets for more information on using pesticides.
- Apply when first noticed or when damage is noticed.
