How to Make Powdered Insect Repellent for Vegetable Gardens

Overview

There are insects that are beneficial to gardens, such as bees that pollinate flowers. Unfortunately, there are a variety of insects that will harm vegetable gardens if they are allowed to remain in the garden. One way to get rid of these insects is to make your own powdered insecticide that will both kill the insects and keep them from coming back. Boric acid is the main ingredient, and it has the ability to keep away ants, slugs, beetles, roaches, and earwigs.

Step 1

Put on a pair of plastic gloves. Boric acid is an all natural product, but it can cause skin irritation in some people.

Step 2

Pour one cup of boric acid in a large plastic container. Boric acid is sold in grocery stores under the name Borax. You can find it on the laundry aisle.

Step 3

Add one cup sugar of sugar and one tbsp. garlic powder to the boric acid, and mix the three ingredients together.

Step 4

Sprinkle around your vegetable garden to kill any insects that are already in the garden, and to deter any new insects from entering the vegetable garden.

Step 5

Create a label for your homemade powder so that no one in the family mistakes it for flour. Use a sticky label and a marker to do this.

Tips and Warnings

  • Never re-use the container with your homemade repellent for storing food.
