This worked well a few years ago but now the carpenter ants just ignore it. I'm using the same bottle I purchased 3 years ago. Do I need a new, unopened bottle of the stuff or have the ants just wised up?
Advance Carpenter Ant Bait has a shelf life of approx. 2 years after opening. You may need fresh bait.
