What's eating my monstera tuberculata?

Monstera tuberculata, like all Monstera houseplants, is most threatened by spider mites and mealybugs. Watch for fine webbing, sticky residue, or cottony white clusters. Inspect leaf undersides regularly, isolate new plants, and treat early with neem oil or insecticidal soap to prevent infestations from spreading to your collection.

Fine webbing on leaf undersides; stippled, yellowing foliage that looks dusty or bronzed Increase humidity, wipe leaves with a damp cloth, then spray with insecticidal soap or diluted neem oil; repeat weekly for 3–4 weeks

White cottony masses in leaf axils and along stems; sticky honeydew and stunted new growth Dab individual bugs with a rubbing-alcohol-soaked cotton swab; follow up with neem oil spray; repeat every 7–10 days

Brown or tan shell-like bumps on stems; yellowing leaves and sticky residue below Scrape off adult scale with a soft toothbrush, then apply insecticidal soap or horticultural oil; repeat monthly until clear

Adult gnats hovering near soil; larvae damage fine roots, causing wilting and slow growth Allow soil to dry between waterings; use yellow sticky traps for adults; drench soil with Bacillus thuringiensis var. israelensis (Bti) or neem soil drench
