Quick answer
If your Orchid has pest infestation, the most likely cause is: Aphids (greenfly) cluster at orchid shoot tips and emit honeydew that grows black sooty mould. Red spider mites cause stippling and pitting on leaf surfaces. Mealy bugs appear as woolly masses in leaf joints. Scale insects create pale spots on leaves. Thrips cause silvery mottling on flowers and leaves.
Start here:
- 1. 1. Aphids: spray with systemic insecticide; remove honeydew manually
- 2. 2. Red spider mites: difficult to eradicate—repeat systemic insecticide applications
