mealybugs on Giant Caladium
Quick answer
If your Giant Caladium has mealybugs, the most likely cause is: Giant caladiums are largely resistant to most pests but are listed as susceptible to several soft-bodied leaf-feeders, and mealybugs in particular settle along the petioles and on the broad caladium leaves, where they pierce the plant tissue and leave the white, waxy residue that gives the colony away.
Start here:
- 1. Wipe the mealybug colonies off the giant caladium's petioles and leaf surfaces with a cotton swab dipped in isopropyl alcohol, working carefully where the stems meet the tuber because that is where the pests hide on aroid-type plants.
- 2. Spray the entire giant caladium, including the undersides of the leaves and the petiole bases, with an insecticidal soap until the foliage is fully coated, and repeat the treatment on a regular interval until no fresh white residue appears on the leaves.

Keep mealybugs off this Giant Caladium
