Natural Pest Control: Interplanting & Homemade Remedies for a Healthier Garden

Chemical pesticides aren’t the only answer to aphids, slugs, and beetles. Generations of gardeners grew abundant harvests using nature’s own defenses. Interplanting—strategically placing certain plants together—can repel pests naturally, while simple kitchen ingredients make effective, non-toxic sprays.

Companion Plants That Repel Pests

DIY Organic Sprays & Treatments

• Soap spray: Strong soap-water solution kills aphids and mites on contact.
• Garlic oil spray: Effective against onion flies, aphids, thrips, ermine moths. (Onion/chive sprays work similarly.)
• Mineral oil on corn silk: Apply with dropper when silks brown to stop corn earworms.
• Salt: Sprinkle directly on slugs/snails.
• Hot pepper + salt + sour milk: Spray for cabbage maggots.
• Paper/tin can collars: Push into soil around stems to block cutworms.

Make Plant-Oil Sprays

Chop/grind plant material, mix with equal parts water, strain, add emulsifier (fish oil or liquid soap). Use immediately—oil separates quickly.

By working with nature instead of against it, you’ll grow healthier, better-tasting produce while protecting pollinators, soil life, and your family’s health.
