TERRO 1 oz Liquid Ant Killer

I've been using this for years and have recommended it to other people that have ant problems. I've always used it for the little tiny black ants because they are attracted to sweet bait. This time I had ants was the absolute worst because they were carpenter ants. These are huge ants and they are destructive. At first I was concerned because they were not eating the bait. But after leaving it out for a couple days they found it and started going to town on it. It took about a week but I no longer see any of them. I know from past experiences with the small ants that they can come back after a month or so when new ants hatch out in the nest. Because even though it kills all of the adult ants and the Queen there are always eggs that need to hatch out and find the bait and die from it also. So, presently I'm waiting for the second wave. It may be different with carpenter ants but that's been my experience with other ants. I highly recommend Terro for your ant problems.
