Treating Spider Mites on Indoor Palms

Identifying the Problem

Sticky residue on fronds + spreading to nearby plants = spider mites. These tiny arachnids suck sap and excrete honeydew. They thrive in dry, warm indoor air.

Alcohol Spray Treatment

1. Mix 1 part isopropyl alcohol (70%) with 1 part water in a spray bottle.
2. Thoroughly coat all leaf surfaces, stems, and undersides.
3. Let sit 4–6 hours.
4. Take plant outdoors and rinse completely with a hose.
5. Repeat weekly until no mites are seen.

Prevention

Mist palms daily or use a humidifier. Group plants to raise local humidity. Inspect new plants before bringing indoors.
