Spider Mites on Hibiscus: Insecticidal Soap Treatment

A hibiscus in a large pot shows yellowing, falling leaves, loss of shine, limp flower branches, and tiny spiders on leaf undersides.

Diagnosis: Spider Mites

These are spider mites (not true spiders)—tiny plant-feeding mites that spin fine webbing. Nearly all plants have specific spider mite pests. They thrive in hot, dry conditions and can rapidly defoliate plants.

Best Control: Insecticidal Soap

• Use genuine insecticidal soap—not household liquid soap (can damage plants)
• Thoroughly cover leaf undersides where mites feed
• Repeat every 5–7 days until controlled
• Increase humidity around plant (misting, pebble tray)
