I have an ant problem and have gone on a never-ending quest to seal off all their points of entry. Believe it or not, I have been surprisingly successful due to how they lead me right back to their entrance, but now I am losing hope.
Two years ago, I filled in a fracture in my concrete slab with Quikrete caulk. It kept the ants from coming in up until now when they figured out that they can burrow through it. Now I'm considering giving up and just moving to ant traps =.
I don't know what type of ants these are, but I don't think they're the big, black carpenter ants. They're also not those microscopic, orange ants. They're the ones in between, the ones you see skittering around on the sidewalk. I'd say they could fit through a hole of a small button.
BTW, while I am technically asking how to get rid of ants, I am specifically asking about seals/caulks/materials that ants cannot/do not burrow through because my goal is to seal off all the points of entry that matter so they stay away from my cat's food dish.

The best treatment is to remove the things that attract the ants. If that is your cat's food dish I suspect that eventually, no matter how many cracks you seal up, that the ants will figure out how to come around the end of the slab and over to what they find attractive as a food source.
So maybe you want to start a regimen with your cat. Put down its food for say half an hour at each feeding and then take it up. Cats can learn to eat on a schedule. But at the same time they will also remind you of the schedule each and every day.
