Pest identification
What's eating my caladium aaron?
Spider mites
Signs: Minute pale dots across white or green leaf areas; webbing underneath leaves; foliage loses vibrancy and drops early.
Control: Maintain humidity, rinse leaves weekly, and apply neem oil or insecticidal soap spray every 7 days for 3–4 treatments.
Mealybugs
Signs: Fluffy white colonies at leaf bases and axils; honeydew and sooty mold reduce the plant's ornamental appeal.
Control: Spot-treat with isopropyl alcohol; follow with systemic neem soil drench where root mealybugs are suspected.
Aphids
Signs: Clusters of soft insects on young leaves; foliage curls and yellows; sticky residue on lower leaves.
Control: Blast with water to dislodge, then use insecticidal soap spray. Outdoors, attract natural predators like hoverflies.
Slugs and snails
Signs: Holes and scalloped edges on leaves at soil level when plants are in outdoor beds; slime trails present.
Control: Use iron phosphate pellets, set beer traps, and remove mulch hiding near stem bases to reduce shelter.
