What's eating my dieffenbachia sparkles?
Spider mites

Control: Wipe both sides of leaves with a damp cloth, use a humidifier, and apply neem oil spray every 7 days for 3 weeks.
Mealybugs
Signs: White waxy clusters at stem internodes; leaves yellow and the plant weakens; honeydew encourages fungal growth.
Control: Spot-treat with 70% isopropyl alcohol; apply neem oil to all surfaces and drench soil for root-dwelling populations.
