One year before we got our new fridge the ants had found a way into the freezer! The would crawl in there and all die. It was the strangest thing we had ever seen. You would open the freezer and it looked like someone had dumped a ton of coffee grounds all over everything! You almost couldn't see the food anymore. We had to use a vaccum to get them all out. this happen at least 4 times. I started putting those little walk into and take back to the nest traps. i don't know if they work but I feel better knowing the cats won't get into it. I tape them around where the cats eat too cause they get into their kibble. so I tape them against the counter wall and under the cabnit as well.
