Ants lay down a scent for other ants to follow. The thing to do is to get rid of their scent. Watch them and find out were they are traveling from and then wash down the path and where they have been with bleach and water.
Joann, I just sent message on mixing power sugar and boric acid tog to get rid of ants, it should have been, Borax-20 Mule Team. So sorry for the error. joanie
Terro is the only thing that works for me. You have to be patient though, the little bummers have to take it back to the nest in order to kill the queen. It can take three or four days before they are gone. Meanwhile, you have to share your kitchen counter with them.
Have you ever tried the Terro ant baits? This stuff is a liquid product that is actually boric acid and a sugar substance. It is a safe product but very sticky if spilled. The ants eat the terro and take it back to their nests. We have had great success with this product. It is also very important to keep the cupboard free from all spills.
I kill them by using non stick cooking spray! It kills them if they are the little black ants.
