How to Get Rid of Japanese Beetles With a Home Remedy Spray

Japanese beetles are a pest to any gardener. They begin their life cycle as a grub that chews on the roots of plants, and as adults they eat the leaves of plants. The Japanese beetle will kill grass, trees and flowers. Getting rid of these insects is difficult, but not impossible. A soapy mixture sprayed on your plants can deter these unwanted beetles and save your plants from being destroyed.

Step 4

Spray the top and bottom of leaves in your garden. Repeat every 2 days.
