A sure way to get rid of pests is to use chemical pesticides and insecticides. But if you have small children or pets that can go outdoors, or if you simply want to live chemically free, you may want to think about some all-natural alternatives. The best chemical-free way to fight pests was detailed in the previous tip, which is with beneficial insects as your personal battalion. And then there are literally hundreds of homespun tricks you can try, including aluminum foil on the ground surrounding the plant base (pests on the underside of leaves don't enjoy it), or your own mix of natural pesticide with powdered charcoal and calcium dust. You can also try smashing some aphids and scattering them among your plants -- it releases a chemical that makes others scram.
