How do you get rid of aphids organically?
[1] Organic responses to aphids include biological, cultural and mechanical options. [2] Biological options tend towards controls, and natural enemies. Controls involve botanicals such as pyrethrins, horticultural and neem oils, and insecticidal soaps. The three may need several applications. But they’re friendlier to the environment, people, and wildlife. Natural enemies involve beneficial insects such as the aphid-eating ladybug. [3] Cultural practices are preventive. They aim to keep stresses and stressors from getting established. Or they try to keep them at a minimum. The biggest stress is drought, which raises the flag for stressor bullies such as aphids. So organic cultivation emphasizes compost, organic mulch, and slow-release organic fertilizers. The three make for aerated, fertile, moist, and well-drained soil. They thereby promote healthier soil, and stronger plants. [4] Mechanical options involve row covers for lower-lying plants and food crops.
