I have tried the borax...they moved 4 feet away and made a bigger home. My DbA** neighbour tried to drown them with water, cold water during a rain storm. LMFAO. This year I am going with the cornmeal. Lucky for us so far they don`t come into the house. Love the cinnimon tip. I now know how to keep them off the neighbours deck.
I have also read where you can pour club soda on the hill and the carbon pushes out the oxygen and gets them.
Sigh, will try any thing to get the neighbour to shut up, looking forward to spring and would rather have the ants than him.
