Garlic Spray: Natural Pest Deterrent

Last Updated on February 5, 2024

Introduction

Concerns over synthetic pesticide use are driving demand for organic pest control options.

One natural deterrent garnering interest from gardeners and farmers is garlic spray.

Made by blending garlic cloves with water, garlic spray offers a chemical-free pest solution.

The strong garlic odor and taste repel many insect pests, while the spray’s antibacterial properties suppress plant diseases.

Garlic spray is especially effective against soft-bodied insects like aphids, mites, and whiteflies.

It also deters fungus gnats, cabbage loopers, spider mites, squash bugs, caterpillars, and Japanese beetles.

The active ingredients that give garlic its pungent smell and insecticidal properties are allicin and other sulfur compounds.

To make garlic spray at home, blend approximately 1 ounce of garlic cloves with 1 pint of water.

Its inexpensive DIY preparation makes garlic spray accessible for home and community gardens seeking to minimize chemical inputs.
