The concentrate effectively deters common garden pests while being OMRI listed for organic practices, ensuring that your gardening methods remain natural.

The Science Behind Garlic Spray
Garlic contains a compound called allicin, which has been shown to have insect-repelling properties. When garlic is crushed or chopped, allicin is released, creating a pungent odor that many pests find off-putting. Research indicates that garlic can deter aphids, beetles, caterpillars, and other harmful insects.
Studies have found that a concentration as low as 1% garlic can effectively repel certain pests. This means that a simple homemade spray can provide sufficient protection for your beloved plants. Not only is garlic a natural solution, but it also breaks down quickly in the environment, making it safe for beneficial insects and pollinators.
How to Make Garlic Spray
Creating your own garlic spray is straightforward and cost-effective. Here’s a simple recipe to get you started:
- Take 1 bulb of garlic and crush it or chop it finely.
- Mix the crushed garlic with 1 quart of water in a spray bottle.
- Let the mixture sit overnight to allow the allicin to infuse into the water.
- Strain the mixture to remove garlic solids and pour the liquid back into the spray bottle.
- Add a few drops of liquid soap to help the spray adhere to plants.
- Shake well before each use and spray directly on affected plants.
This homemade garlic spray can be applied every 5-7 days or after rain. Keep in mind that the odor will dissipate after a short time, so it won’t linger in your garden.
