You’ll create an effective garlic sulfur spray by crushing two fresh garlic bulbs and blending them with hot water, then steeping for 2-3 days before straining. Dilute the concentrate at a 10:1 ratio with water and apply during early evening hours to avoid leaf burn. This natural deterrent confuses pests like aphids and slugs while providing antifungal benefits, costing less than $5 for multiple applications that’ll protect your entire garden naturally and sustainably.
The Science Behind Garlic’s Pest-Fighting Properties
When you crush or chop garlic, you’re releasing a powerful chemical transformation that turns this common kitchen ingredient into nature’s pest control system. The secret lies in garlic’s sulfur compounds, primarily alliin, which converts to allicin when the cell walls break.
This conversion creates the pungent smell that makes garlic so effective against garden pests. Allicin’s unique odor confuses insects by interfering with their sensory receptors, effectively repelling aphids, slugs, and mosquitoes.
When you prepare a garlic spray, you’re harnessing these same compounds that also provide antibacterial and antifungal benefits. The high sulfur content doesn’t just repel pests—it actively prevents molds and fungi, promoting overall plant health while offering an eco-friendly alternative to synthetic pesticides.
