Hopefully all this has helped, and you wont be living in the trenches of the human-ant battlegrounds any more.
Step 2: Preparing the Poison
Take your cup or bowl, your spoon, and the borax and jelly. You'll want the solution to consist of no more than 5% borax. So, the easiest way is to take ten spoonfuls of jelly and put them in the cup/bowl. Then, you'll want half a spoonful of borax. This recipe can be extended to twenty spoonfuls jelly and one of borax, if you need that much.
Now, mix it in really well! You'll have to be deceitful - it's poison, after all.
