Amblyseius andersoni Bottled - Introduction Rates
Bottled Release Rates
General starting points. Adjust for the pest, the plant and how bad the infestation is, and check pests and predators regularly.
- Light infestation: 2–5 mites per sq. ft., every 1–2 weeks
- Heavy infestation: 5–7 mites per sq. ft., every 1–2 weeks
For a heavy infestation, don't just raise the andersoni rate. Combine it with a spider mite specialist and bring the pest population down with an IPM approach.
