Pest identification
What's eating my pansy orchid?
Spider mite
Signs: Fine pale stippling on thin leaves; 'accordion pleating' distortion on new leaves (a classic Miltoniopsis mite symptom); webs in severe cases.
Control: Raise humidity to 60–70%; wipe leaf surfaces with a damp cloth; apply very dilute insecticidal soap or neem oil carefully; repeat weekly.
Scale insect
Signs: Brown flat oval bumps on undersides of leaves and on pseudobulbs; yellow patches on upper surface above each scale.
Control: Scrape off gently; wipe with isopropyl alcohol on a cotton pad; apply diluted neem oil; inspect all neighbouring orchids.
Mealybug
Signs: White fluffy wax at pseudobulb bases and between leaves; affected plants lose vigour; honeydew attracts sooty mould.
Control: Dab with alcohol swab; remove wax manually; apply neem oil drench to the medium; isolate the plant.
Fungus gnat
Signs: Adults hover at compost level; larvae damage the fine root system in the bark mix, causing yellowing and stalled growth.
Control: Do not overwater; allow medium surface to dry slightly; apply Bti (Steinernema feltiae) nematode drench; yellow sticky traps for adults.

Pansy Orchid pests — FAQ
What is eating my pansy orchid?
Pansy orchids (Miltoniopsis) need cool, humid conditions — the same conditions that attract spider mites when humidity drops and scale insects on mature leaves. Mealybugs shelter at pseudobulb bases. Fungus gnats breed in the fine bark medium. These cool-growing orchids are sensitive to chemical sprays; use diluted, mild treatments.
