I was skeptical about how well these would work but they do! We have an outdoor patio couch/ottoman/chair set and the mice get up on it at night, leaving their disgusting little droppings for me to clean up the next morning. I bought these as a cheap way to keep the mice off the couch. The package says to use in an enclosed area however for the price, I figured I'd see if it would work in an outdoor space. They do, however because the space is outdoors and not enclosed, they definitely lose their potency much quicker than if I were to use them in an enclosed space. I set one on each corner of the couch (it's a sectional, pouches were about 4' apart) and one on the ottoman and they worked for about a week and a half-two weeks out in the open like this (which was a pleasant surprise). If I needed them in a house/pantry/garage/RV and/or other enclosed area I firmly believe they'd do the job well. I gave some to my neighbor to try out in their RV so I'll try to update this review when I talk to them next.

I bought a box of these and threw them in all the compartments of my RV, particularly the one where the electrical cord opening is. I caught two mice in my RV with traps before placing these - afterwards, I had no evidence of mice inside at all, and caught no more in the traps. Next year, I need to put one in the generator bay, as that's where they went to nest instead :-(

What can I say? This is great! It smells great (not that toxic smell) and so easy to use - just open package and place in a dark place (mine are in my garage). I originally bought this product because I do not use chemicals of any kind in or around my home. I have plants and a small dog but I also don't want unnecessary chemicals in the air that I breath. I would highly highly highly recommend this product and this seller

Absolutely useless, my three little rats totally ignored the product and came out to play anyway. Now I have had to set traps which I really did not want to do. Yuck

Put one in my girlfriends glove box and the mice actually built a nest on top of it within about 3 days. Not sure if I got a bad batch or if this is really that useless of a product?
