"they work"
These really do work. I was amazed. I had spent a lot of time and money on less eco-friendly products (and always worried about the effect they were having on us and the dogs as well) and wasn't happy with anything. Then I tried these . . . *and they work.* I find you do have to use kind of a lot of them, and replace them pretty promptly, and you have to have a high tolerance for the spicy smell . . . but I find them absolutely worthwhile. Last year was a very bad year for moths locally, and I had friends who lost half their wardrobes. I had one dress chewed on--because I'd forgotten to replace its sachet.
