Mealybugs on Kentia Palm: Identification and Safe Treatment

Mealybugs on Kentia Palm: Identification and Safe Treatment

A cottony white substance on new growth of a Howea forsteriana (Kentia palm) is a classic sign of mealybugs. These sap-sucking insects hide in leaf axils and along stems, weakening the plant and producing sticky honeydew.

Effective Low-Toxicity Treatment

Mix a solution of one part rubbing alcohol to five parts water with a squirt of liquid soap. Thoroughly spray all leaf and stem surfaces, paying special attention to crevices where leaves emerge. Repeat weekly until no pests are visible. This method penetrates the mealybugs’ waxy coating without harsh chemicals.

Light Requirements for Kentia Palms

Kentia palms thrive in low to moderate indoor light. Avoid direct outdoor sun, which can scorch leaves. Place the palm near a bright window but out of direct rays. Consistent, appropriate light reduces stress and helps the plant resist future infestations.
