Insects!

As a gardener, there's nothing more frustrating than finding a prized vegetable crop being devoured by insect pests. A couple of hornworms can level a row of tomatoes overnight. Fortunately, every pest has a predator, and we can use that natural food chain to our advantage. A sufficient number of beneficial insects will keep garden pests to manageable numbers. You just have to know how to attract those beneficial insects to your garden.
