I was very happy to find the product (copper mesh) as it has been impossible to find locally. My handyman and I went thru the entire basement, plugging in mesh and then foam sealing, and the pest-y problems I was having have stopped. I was happy to have the product SO QUICKLY (not expected!) as the phone helper said she would try to get the product in the mail quickly (I ordered late on a Friday.) Next week - voila! I am very pleased :-D
