Home Grown: Aphid Control Without Chemicals

Aphid lion larvae consume approximately 400 aphids a week. They compete with lady bugs, parasitic wasps, minute pirate bugs, hover fly larvae, predator stink bugs, praying mantises, assassin bugs, damsel bugs and other beneficial insects for aphids, often making it unnecessary for gardeners to use chemical sprays.

Aphids are phloem feeders, or plant-sap suckers. They congregate on the growing tips of garden plants or on the underside of the leaves. They are small and round and produce a frass (excrement) called honeydew that collects on the plant leaves, making them sticky.

A garden’s aphid population builds at a very high rate due to asexual reproduction by the females giving birth to already pregnant clones. A female aphid can produce 5 to 12 offspring in one day.
