When we moved to a neighborhood that had a robust farmer's market, we thought it was the house that came with a moth problem. Turns out, it was the organic grains we were bringing home, and the moth infestation spread to all kinds of foods like chocolate, dog treats, and oats. We tried everything to get rid of them, when someone recommended these. Almost instantly, the problem was at bay. Any time there is a flare up, we put out a few traps and it's under control quickly. Highly recommend!
