Pest identification
What's eating my monstera deliciosa ronronensis?
Spider mites
Signs: Yellow stippling across large leaf surfaces; webbing concentrated near fenestrations and on undersides in warm, dry rooms.
Control: Shower the plant thoroughly, keep humidity above 60%, and apply neem oil or miticide spray every 5–7 days until clear.
Mealybugs
Signs: White cottony clusters at petiole axils, leaf sheaths, and on aerial roots; honeydew and sooty mold may follow.
Control: Swab with 70% isopropyl alcohol, then treat with diluted neem oil or insecticidal soap; isolate the plant and recheck weekly.
Scale
Signs: Hard brownish bumps on stems and petioles; leaves dull and sticky; slow overall growth.
Control: Manually scrape scale off and apply horticultural or neem oil; inspect aerial roots as well since scale hides there.
Thrips
Signs: Bronze or silver streaks on new leaves; tiny black frass spots; new growth may emerge deformed.
Control: Use spinosad or insecticidal soap spray and blue sticky traps; remove heavily damaged leaves and treat consistently for 4–6 weeks.
