What's eating my aglaonema nitidum?

Aglaonema nitidum, a large-leaved tropical species from Southeast Asia, is most often plagued by mealybugs and spider mites indoors. Its broad leaves are a prime target for spider mites in dry air. Regular wiping with a damp cloth removes dust and deters mites while revealing early-stage infestations.

White fluffy masses at stem nodes and leaf bases; significant populations cause leaf yellowing and drop Remove with alcohol swabs; isolate plant; apply diluted neem oil spray weekly; repeat for a minimum of 4 weeks

Yellow or silvery stippling visible on the large leaf surface; webbing underneath; heavily infested leaves dry up Wipe leaves top and bottom with insecticidal soap solution; spray thoroughly every 5–7 days; improve humidity to discourage re-infestation

Small brown raised bumps on leaf midribs and stems; plant weakens gradually with reduced leaf size Manually remove scale with a toothbrush; treat with horticultural oil spray every two weeks for 6 weeks
