What's eating my peperomia 'napoli nights' (dark form)?

Peperomia 'Napoli Nights' dark form is a slow-growing cultivar prone to mealybugs and fungus gnats like most peperomias. Its dark, fleshy leaves can hide pest activity, so inspect undersides and stem bases regularly. Avoid overwatering, which triggers fungus gnats. Treat with neem oil or insecticidal soap at the first sign of infestation.

White cottony residue at stem joints and leaf undersides; sticky honeydew and leaf yellowing Remove with isopropyl alcohol swab; apply neem oil spray weekly for 3–4 weeks

Root damage from larvae in waterlogged soil; adult gnats visible near the pot surface Let soil dry between waterings; use sticky traps and Bti drench to break the cycle

Fine pale speckling on dark leaves, most noticeable against the deep foliage color Spray undersides with insecticidal soap; increase humidity around the plant
