Spider Mite Control on Phalaenopsis: Chemical and Eco-Friendly Options

Nwe Lay submitted photos of pests on a Phalaenopsis, asking for eradication methods. The expert listed effective miticides: Kelthane, Temik granules, diazinon—repeated every 2–3 days until all hatchlings are gone. For eco-friendly options: predatory mites (hard to source), Neem oil (Dyna-Gro), and Cinnamite (Mycotech Corp., cinnamon-scented). Both plant-derived sprays require repeated applications.

Mites have five stages; only later stages show red coloration. The expert prefers systemic granular insecticides absorbed into plant tissue, effective for 6+ weeks, though mites have a non-feeding dormant phase. Constant monitoring and isolation of infected plants are essential.
