I have seen this concoction on quite a few websites so, this is not my recipe.
Step 1: How To Concoct It
1 Gallon of water
1/4 Cup orange oil
1/4 Cup Blackstrap Molasses
Some sort of sprayer (or you can just pour it on the bed)
Simply mix together all of the ingredients.
Note: makes enough for one ant bed.
Step 2: The Spraying/Pouring
Step 3: The End (if you did it right)
Make sure you soak the ground VERY well so that no ants survive.
