spider mites on Phalaenopsis Orchid
Quick answer
If your Phalaenopsis Orchid has spider mites, the most likely cause is: Phalaenopsis spider mites are tiny arachnids (eight legs, not six like insects) that feed on leaf undersides, causing stippled yellowing, fine webbing, and leaf damage. Spider mites thrive in hot, dry conditions (above 80°F with low humidity) and reproduce rapidly in indoor environments. They are often introduced on new plants or via wind currents from open windows.
Start here:
- 1. Identify spider mites: fine stippling (tiny yellow dots) on leaf tops, fine webbing between leaves, moving dust specks (look closely)
- 2. Isolate affected plant immediately - spider mites spread by wind and contact
