These microscopic pests feed on garlic bulbs, causing damage and reducing bulb quality. To manage garlic bulb mites, practice crop rotation, maintain proper soil drainage and moisture levels, and consider using organic insecticides or predatory mites that feed on these pests. These maggots feed on garlic roots, leading to stunted growth and reduced yields. To control onion maggots, use row covers to prevent adult flies from laying eggs near garlic plants, apply insecticidal soil treatments, and consider using beneficial nematodes that target maggot larvae.
