Pest management using beneficial organisms (predators, parasites) that naturally feed on pests, reducing pest populations without chemicals.
Instead of spraying pesticides, encourage beneficial insects that eat pests. Ladybugs eat aphids. Parasitic wasps lay eggs in pest insects. Spiders eat many pests. Attract beneficials by planting flowers (pollen and nectar), avoiding broad-spectrum pesticides (kills beneficials and pests), and providing water. Over seasons, beneficial populations suppress pests naturally.
Biological control is sustainable, doesn't require spraying, improves over time as beneficial populations establish, and supports ecosystem health.
