What's eating my anthurium brownii?

Anthurium brownii is a tropical aroid grown indoors or in warm greenhouse conditions. Spider mites are the most common and damaging pest, exploiting low indoor humidity. Mealybugs often colonize the sheathing bases of its petioles, which are difficult to inspect. Fungus gnats are a risk in overly moist growing media. Good cultural practices are the best prevention.

Fine pale stippling across leaves, loss of sheen, and webbing on undersides in dry conditions Boost humidity, shower the plant weekly, apply insecticidal soap or neem oil; miticide for heavy infestations

Cottony white clusters hidden in petiole sheaths and along stems; sticky honeydew residue Remove with alcohol-soaked swabs, follow up with neem oil spray; inspect bi-weekly to prevent resurgence

Larvae chew fine roots in wet soil; adult gnats are a nuisance; plant may wilt or yellow Reduce watering frequency, top-dress with sand or grit, use Bti drench and yellow sticky traps
