Pest identification
What's eating my pink mandevilla?
Spider mites
Signs: Yellow stippled dots on upper leaf surface; fine silk webbing under leaves; foliage dries and drops.
Control: Mist foliage regularly to raise humidity; spray with insecticidal soap or neem oil every 5–7 days.
Mealybugs
Signs: Cottony white deposits in leaf axils and stem joints; honeydew leads to sooty mold.
Control: Dab with isopropyl alcohol; apply neem oil drench weekly until infestation resolves.
Scale insects
Signs: Waxy bumps on stems; sap extraction weakens vines and triggers sooty mold on leaves.
Control: Scrape off with alcohol-moistened swab; follow with weekly horticultural oil applications.
Whitefly
Signs: Tiny white insects fly up when foliage is disturbed; nymphs suck sap causing leaf yellowing.
Control: Spray leaf undersides thoroughly with insecticidal soap or neem oil three times at 5–7 day intervals.
