What's eating my anthurium andraeanum 'roseum'?

Anthurium 'Roseum' is targeted mainly by sap-sucking indoor pests. Mealybugs are the most common threat, hiding in leaf axils and along stems. Spider mites attack in dry conditions, while scale insects cluster on stems. Fungus gnats signal overwatering. Wipe pests off promptly and improve air circulation to stay ahead.

White cottony clusters in leaf axils and stem joints; sticky honeydew residue on leaves Dab colonies with 70% isopropyl alcohol on a cotton swab; follow up with neem oil spray weekly for 3–4 weeks

Fine webbing on leaf undersides, stippled or bronzed leaf surfaces, especially in low humidity Rinse foliage under a shower, then apply insecticidal soap or neem oil; raise humidity above 60%

Brown or tan bumps fixed to stems and midribs; yellowing leaves and sooty mold from honeydew Scrape off scales manually, then treat with horticultural oil or systemic imidacloprid for heavy infestations

Larvae chew fine roots causing wilting and stunted growth; adults are a nuisance around soil Allow top 2 inches of soil to dry between waterings; use yellow sticky traps and drench soil with Bacillus thuringiensis var. israelensis (Bti)
