Unfortunately my moth problem has actually gotten much worse since I started using this product, which has done absolutely nothing. Daily I see moths fluttering about right by these hanging units, which are clearly utterly ineffective. I will have to continue my search for a safe, semi-odourless, non-invasive product that won't poison me or my pet bunny along with the moths. You're far better off not wasting your hopes and money on this product, but selecting an alternative instead, as I shall now be doing.
