Because they are attracted to some of the ingredients in this homemade grub killing agent, you will be able to attract and successfully do away with these grubs, and get your lawn back to its old self again.

Step 1

Bring 8 cups of water to boil in a pot. Remove the pot from the heat and allow the water to cool to a lukewarm temperature. Pour the lukewarm water into a large glass jar.

Step 2

Add 2 tbsp. of Borax laundry assistant and 1 tbsp. of liquid dish detergent to the water and mix well.
