Persistent Spider Mites on Miniature Rose in Japan

Webbing, eggs on leaf undersides, and curling/falling leaves confirm spider mites. They thrive in hot, dry conditions. Chemical sprays often fail due to resistance and egg protection.

Effective Non-Chemical Eradication

1. Enclose pot in plastic bag, tied at base.
2. Place under lukewarm tap; thoroughly wash entire plant—undersides especially.
3. Let sit in sink (don’t shake off water) for 10 minutes.
4. Repeat daily for 5–7 days.

Water drowns mites and eggs. Increase humidity; avoid hot, dry locations. If infestation returns, repeat.
