Garlic makes a great organic pesticide. Not only should you plant it among your other crops (either veggies or ornamentals), you can use it to make a foliar spray and apply directly to leaves, especially lettuces. This garlic spray works as a repellent, sending most pests scurrying away in a hurry.
How to Make Garlic Organic Pesticide Spray
You’ll need two ingredients:
1.5 cups of warm water
2 bulbs of garlic
1. Blend them into liquefied slurry in your blender.
2. Strain out any pieces of garlic that remain.
This makes for enough concentrated insecticidal liquid for a gallon of the spray, which you can then put into a spray bottle.
Use garlic pesticide to combat pests as varied as Japanese beetles, chinch bugs, slugs, grubs, snails, thrips, and grasshoppers. It can also repel larger pests like deer and rabbits.
To save time, double or triple the amounts in the recipe. If you don’t need all the garlic insecticide you’ve made at once, you can freeze it in quarter-cup portions.
