Pest identification
What's eating my chocolate orchid?
Scale insects
Signs: Brown, waxy or shell-like bumps fixed to pseudobulbs, stems, and leaf undersides; sticky honeydew and sooty mold follow.
Control: Dab individual scales with a cotton swab dipped in 70% isopropyl alcohol. For heavy infestations use horticultural oil spray; repeat every 2 weeks for 6 weeks.
Spider mites
Signs: Silvery or bronze stippling on leaves, fine webbing at leaf junctions, and overall dulling of foliage — worst in low-humidity indoor air.
Control: Increase humidity around the plant; wipe leaves with a damp cloth and treat with neem oil or insecticidal soap spray. Repeat weekly.
Mealybugs
Signs: White cottony masses in pseudobulb sheaths, leaf axils, and root crowns; leaves yellow and growth stalls.
Control: Remove with alcohol-dipped swabs, flush roots with water, and spray with insecticidal soap. Isolate the plant immediately to prevent spread.
