What's eating my urn plant (aechmea fasciata)?

Urn Plant (Aechmea fasciata) is generally pest-resistant, but scale insects and mealybugs target the leaf axils and the central tank. Spider mites appear in dry indoor air. The central water cup can breed fungus gnat larvae if the trapped water becomes stagnant — flush and refill regularly.

Hard brown bumps on leaf surfaces and edges; yellowing; sooty mold on honeydew deposits Scrape off with a soft toothbrush; wipe with isopropyl alcohol; apply horticultural oil spray

White waxy fluff in leaf axils or inside the central rosette; stunted growth; sticky residue Remove manually with alcohol swabs; flush the tank with fresh water; spray with diluted neem oil

Fine stippling on broad leaves; webbing visible in severe cases; foliage loses sheen in dry air Mist leaves, increase humidity, apply insecticidal soap or neem oil spray; repeat weekly
