Controlling Spider Mites on Indoor Tropical Plants Without Repotting

Banana and Hawaiian plants indoors for winter were loaded with spider mites. Banana plant reduced to new growth only.

Good News

Spider mites do not live in soil. No need to repot or treat soil.

Treatment Steps

1. Blast leaves (especially undersides) with strong water spray to dislodge mites/eggs.
2. Spray entire plant with soapy water (1 tsp dish soap per quart).
3. Rinse thoroughly after soapy spray.
4. If more than a tiny bit of soapy water enters soil, flush 3× with distilled water and empty tray.
5. Increase humidity (pebble tray, grouping) after mites are gone.

Banana Plant Specifics

• Bright light, no direct sun.
• Water when top 2 inches dry.
• Fertilize lightly & often (½ strength balanced liquid) while actively growing.
