Homemade Natural Garlic Pesticide

Now that I officially have green fingers (ok, so I don’t have green fingers…but I’m at least trying to get a green thumb), I’m thinking about pest control. It would be a shame to lose my wonderful fruits and veggies to little bugs. However, I despise conventional poisons, and refuse to use use them on my food, if at all possible.

So, I made a batch of homemade natural garlic pesticide. Did you know that garlic insecticides are good for pests such as ants, aphids, apple maggots, caterpillars, chinch bugs, codling moths, cutworms, earwigs, sowbugs, flies, grasshoppers, grubs, Japanese Beetles, leafhoppers, leafminers, loopers, mealybugs, mite, pysillids, scale, slug, snails, thrips, and whiteflies? Sounds good to me!

I used this on my last garden, and had NO pests. Seriously.

Recipe: Homemade Natural Garlic Pesticide

12 cloves garlic

1.5 cups water + 1 gallon water

Blend together the 12 cloves garlic and 1.5 cups water. Strain out the garlic pulp.

Pour the strained garlic water into a large container (large enough for at least a gallon). Add 4 quarts (1 gallon) of water. Shake to combine. Pour some into a spray bottle and spray your plants once a week to help ward off pests!

Here’s a video of how to do the process:


Store in a cool place for up to one month to ensure potency levels stay intact.

      No, it doesn’t need to be kept in the refrigerator, just stored in a cool place, but you will probably want to use it within a month to make sure the potency level is high enough.

    I haven’t tried this recipe yet. We discovered companion gardening years ago and since planting borage flower next to our tomato plants have not had tomato worms (horn worms) for over 15 years.

      That’s a good tip, Cheryl, but I *like* tomato hornworms! They are bonus little protein balls for my chickens. 😀 I’ll share your tip with chicken-less friends.

        I know what you mean. We used to feed them to our dogs when we were still getting them. In fact, one dog would go hunting on her own. She’d come in the house with a green face from poking around in the tomatoe plants.
