What's eating my spathiphyllum 'mauna loa'?

Spathiphyllum 'Mauna Loa' is a popular tropical houseplant attacked primarily by mealybugs, spider mites, and scale insects. Its lush, broad leaves attract sap-sucking pests in the warm indoor environments it requires. Mealybugs sheltering at leaf bases and in the crown are the most common and damaging pest found on peace lilies.

White cottony clusters at leaf bases, petioles, and in the crown; leaves yellow and plant wilts Remove with alcohol-soaked cotton swab; spray neem oil or insecticidal soap; drench soil if root mealybugs suspected; isolate from other plants

Pale stippling across broad leaves and fine webbing on undersides; leaves yellow and drop in dry air Mist leaves regularly; wipe undersides with damp cloth; apply insecticidal soap; keep away from radiators and dry heating vents

Brown waxy bumps on leaf midribs and stems; honeydew causes sticky leaves and sooty mold Scrape off with a soft toothbrush; apply horticultural oil or neem oil; use systemic treatment for heavy infestations
