Organic Pest Control Series: Beneficial Insects

Day and night, pesticide-free organic gardens are abuzz with activity, much of it a life-and-death struggle between predators and prey. We seldom see much of this natural pest control, in which tiny assassins patrol their surroundings in pursuit of their next meal. Assassin bugs aren’t picky: They will stab, poison and devour a wide range of garden pests, including caterpillars, leafhoppers and bean beetles. Soldier and ground beetles work the night shift, emerging after dark from beneath rocks, mulch and other daytime hiding places to feast upon soft-bodied insects and the eggs of Colorado potato beetles. Aphid lions (the larvae of the lacewing) have a hooked jaw that helps them dispatch huge numbers of aphids, caterpillars, mites and other pests.

Learning about the beneficial insects in your garden will make it a more fascinating place, and help you tweak it in ways that intensify the work done by wild garden allies. This is often a simple matter of avoiding the use of pesticides (including organic ones) and growing plenty of flowers to provide beneficial insects with pollen and nectar. In greenhouses or other special situations, you may even decide to purchase and release certain lab-raised beneficial insects. This will not be necessary with the beneficial insects described here, because all will naturally gravitate toward a diversified organic garden.

Below we feature the best beneficial insects for your garden, each one beautifully illustrated. Get to know these garden helpers individually and make a plan for how you can incorporate them into your garden as part of your natural pest control strategy.
