It's best to use the little round boxes that you get in the shops in the U.K. you just put them down and the ants go into them and carry the contents back to the nests to be eaten, of course, it's poison and they don't come back.
We always take a stock of these ant traps with us as they don't sell them in Turkey. Once, when we forgot to take them we asked in the D.I.Y. Shop in Fethiye and the guy sold us some powder. I asked "Does it kill them? and he told me "No, it just sends them away". So, I assumed they go next door.
