Worked the same for me. NOT AT ALL. Terro did nothing for me. I called the company and was told that it takes time for the ants to carry it back to the nest. I have tried it again this year, with the same results.

worked for us
 

Boric acid in powdered sugar in a little container, or if your ants prefer protein, a little peanut butter, give it a couple days and ants will be gone

My dad always swore that Formula 409 got rid of ants in their kitchen. It took two applications a day or two apart.

Every place I put the liquid Terro on the little cardboard dot, the ants had a party and invited everyone they had ever known. No it did not stop in a couple days. I think they were importing them from another state. They loved the stuff but don't think it killed one of them. Now the bait you put outside, that stuff worked pretty well.

I saw somewhere that if they eat corm meal they will die and also take it back to the hill and kill more ants

I would take chalk and run a thick line around the window where they seemed to be coming. They also come in the water lines according to the pest folk.

We tried the borax, sugar water thing and I watched the ants go pass it. They would not go to it.
We replaced a greenhouse window with a regular window and that fixed the problem.

I also use Terro. When you first put it down it seems to draw the whole family & friends but after a couple days they are all gone. I really like the stuff. It almost looks like it makes them half drunk because they will just hang around & look half dead but when you go to pick them up to throw them away then they scatter. Really odd. It does work good for me though
