Since we have young kids, I put one out around 6PM the night before and kept my kids away from it. Around 8 that one had drawn enough attention, I set up one more.
By midnight the container was hopping.
First thing the next morning I went to remove the traps.
The ants had completely cleared out. Over the next few days we still found a few stragglers, but nothing worth getting out the borax again. No infestation upstairs this year either. It seems being proactive nipped it in the bud.
So crazy and worked so fast, I just had to share.
