Be sure to read the reviews on this product
The reviews that say these pouches smell wonderful when first place are correct.  The ones that say that this effect does not last are also correct.  I have sprayed them twice now.  The original application lasted about 4 days, but the re-sprays did not last at all.  Possibly a rodent with its nose closer to the bag might smell it and be put off by it, but I have my doubts.
