Organic Japanese Beetle Control: Soap, Pyrethrin, and Realistic Expectations

Organic options exist, but they require direct contact and frequent reapplication:

Neem oil—labeled as a repellent, but Ohio research shows limited effectiveness.

No organic silver bullet. Hand-picking into soapy water remains the most reliable organic method.
