Eradicating Spider Mites on a Long-Term Indoor Palm: Spraying, Washing, and Humidity

Webbing = Spider Mites

18-year-old indoor palm with webbing and drying new shoots: classic spider mite infestation from dry winter air.

Treatment

1. Spray insecticidal soap or horticultural oil (Ultra-Fine).
2. Let work overnight.
3. Wash off next morning (hose or shower).
4. Mist daily forever after.

Soil Refresh

Repot annually. Change soil, add gravel base. Water periodically during repotting so roots don't dry completely. Misting is the mite deterrent.
