What's eating my pride of brazil orchid?

Pride of Brazil (Cattleya purpurata) is a large-growing species prone to scale insects and mealybugs, which hide inside the thick sheaths protecting its sizable pseudobulbs. Spider mites can attack during dry winters indoors. Stripping old sheaths quarterly and treating with alcohol at first sight prevents major infestations.

Brownish armored or soft waxy bumps on pseudobulbs and leaf underside; honeydew and sooty mold on leaves below Scrub with alcohol-soaked cloth or toothbrush; spray horticultural oil; repeat every 3–4 weeks until no live insects found

White cottony deposits in sheaths, at root collar, and between pseudobulbs; stunted new growth Dab with isopropyl alcohol; remove papery sheaths; apply neem oil solution at 7–10-day intervals; isolate plant

Pale, stippled leaf surface; fine webbing, especially on undersides during dry heating-season conditions Boost humidity; apply insecticidal soap or diluted neem oil spray; wipe leaves; repeat weekly for 3–4 weeks
