If I see a conga line of ants, I make a cinnamon line to break it up...or..I spray windex multi vinegar around my container. Instant kill. But I do not spray in the pot itself. I can water the pot to coax those ants to scatter out, then I spray windex outside the pot. There is this organic spray that works too...just very strong eucalyptus smell though. Good for spraying outdoors. My ultimate last resort is Diatomaceous earth too.
