- At planting time: Plant resistant types—types resistant to aphids and the diseases they create about. Interplant crops with chives, garlic, mints, onions, and petunias which repel aphids. Fleece floating row covers to exclude pests from seedlings and transplants.
- While crops develop: For delicate infestations spray smaller plants regularly with a formidable circulate of water to knock aphids off—no less than every other day until the colony is long gone. Use insecticidal cleansing cleaning soap every 2 to a couple of days for large infestations; use do-it-yourself garlic sprays (mix chopped garlic with water) or sizzling pepper sprays—the ones spray must hit the aphids to kill them; as a last resort, spray with neem or pyrethrin.

Animal predators include chickadees, nuthatches, pink finches, warblers, chipping sparrows, and toads.
Scientific Determine: Aphis fabae (bean aphid), Myzus persicae (spinach aphid), Acyrthosiphon pisum (pea aphid), Eriosoma lanigerum (woolly aphid).
