I have tried to use borax to kill ants. Upon first application, I made a paste using sugar and borax then I soaked cottonballs and placed in areas where I saw ant activity.
Now the cottonballs are wet but covered with a crust of the solution that has dried out. Should I throw them away and make a new one, or wet it and leave it?
Also, I do not know whether making the paste and leaving it in small dishes is also a solution.
