Natural Home & Garden Pest Control with Andy Lopez

Sunday, August 9, 2026

On this episode of Dr. Health Radio, host David Snow (“the snowman”) welcomes Andy Lopez—known as The Invisible Gardener and once called “the King of Compost” by the Miami Herald—for a practical conversation on natural home and garden pest control.

Andy shares time-tested, chemical-free alternatives that actually work: food-grade diatomaceous earth, boric acid solutions, pure white vinegar, citrus essential oils, Dr. Bronner’s castile soap, cold-brewed coffee (caffeine), and compost tea. He explains why pests are usually a symptom of unhealthy soil biology and how building living soil is the best long-term defense against ants, cockroaches, and garden invaders.

You’ll also hear why city water can harm soil life, the importance of earthworms and true compost, and simple steps to keep both your indoor spaces and outdoor lawn or garden thriving without toxic pesticides and herbicides. Plus, David covers related health notes on heat, hydration, microplastics, and more.
