Ants are gone!

We've had an ant problem in our kitchen for a couple of months. I'd tried to get rid of them with ant bait gel (the stuff that the ants take back to the nest...kills the queen...ant's disappear), but it just didn't work. There'd be a stack of them on the bench, we'd clean them up, and they'd be back again. And then a couple of days ago, they started getting into the bin in which we collect the scraps for the compost/bokashi. So it was time to attack with all guns blazing - 'Professional strength NO MORE BUGS'...and they are Gone! I haven't seen a single ant today. I'm glad the battle is over.
