Can you identify these ants?

Looks like the ant hill mob, Big Gus, Little Paul, Joey short pants, The rest i do not know.

They look like ghost ants to me(I'd say I'm positive if they were here that's what they are, but I don't know where you are or the species there). Bait is the way to go. Usually there will be many outside which is where they come from. If it is cold there, they may have moved in also. You can try different liquid baits from the store or mix your own using various sweeteners and a 1-2% solution of boric acid. Do trials to see what they like first, then mix it with the boric acid. Cornmeal may work, although usually sweet baits are best in the winter. Put some cornmeal out and tell me if they like it. I'd like to know.

Don't spray any over the counter stuff.

Any luck? Don't spray anything.

To make a 1-2% solution, use 1/4 cup of corn syrup, honey, or whatever they like, and add 1/8-1/4 tsp of boric acid.
