What are three ways in which home gardeners can avoid or reduce pesticide use in their yards or gardens?

Keep it well manicured-decaying leaves provide food & privacy for many insects, use as little water as needed-excessive moisture conditions are asking for snails. Don't let fallen fruit or produce with any openings to sit & attract them or rodents. Many bugs only feed on produce when the skin is broken. Sprinkle salt or ditamacheous earth as a natural deterrent.
