Shake-Away 4152424 4CT Mouse Repellent Packs, 1.5-Ounce

I have used this product for years. It comes in small packets which you shake and put in areas where you do not want mice. Smells like pine. Before I discovered this product, I had mice living in the headliner of my car. I now put the packets in my glove compartment and several other areas in my new car. We live in the middle of 100 area, and this product protects our cars wonderfully.

You just set them out! Smell isn't bad! Haven't seen or heard mice yet!

I have used these packets inside my garage on each side of the door that leads into the house for several years. I change them every two months as directed . Since I began using the packets we have found very few mouse droppings in the area around the door and throughout the rest of the garage. It is impossible to keep mice completely out of the garage due to the opening and closing of doors to the outside and screen doors that have gaps in the cement at the bottom. Based on our experience and evidence, if they come in, it seems to send them packing before they make nests and messes or destroy anything.

Happy to say the mice do not like it...so they stay away!

I use this in my garage, vehicles and house.

Not to sure if these actually work or not. I caught a mouse in a trap right next to one of these packets.

I have had a major mouse infestation in my car, and this stuff keeps them away without stinking me out of the passenger compartment. I also use it in my barn and in my house when I see signs of mice and pack rats getting in. You do have to replace the packets every two months or so--and it tells you that on the package.

To find out whether this product repels mice, I ran a controlled experiment, which I'll describe here.Methodology:Two identical cardboard boxes, 7 x 10 x 5 inches, were prepared. These were closed at the top and bottom and had a triangular opening on one side near the bottom. A stamp pad was placed at this entrance to each box, so that any mouse entering the box would have to walk over the stamp pad, thus getting its feet inky. A sheet of paper was placed on the bottom of the box, and any mouse exploring the interior of the box would leave its inky footprints on this paper. One of these Shake Away repellent packets was hung inside one of the boxes. No bait was put inside the boxes, out of concern that the peppermint smell of the Shake Away packet might reduce the traffic of mice simply by masking the smell of the bait. Thus the boxes were just a dark, enclosed space of the sort that mice are prone to investigate.Over the course of four days, the boxes were alternated every 24 hours; the "active" box being put in the same place on the floor of a crawlspace under my house, while the "inactive" box was removed to a separate area and sealed so that no mice could enter it. through this methodology, the comparative density of mouse footprints on the sheets of paper placed on the bottom of the two boxes gives an indication of how effectively the Shake Away packet kept mice from exploring the box.Results:As you can see in the photos that accompany this review, the box with the Shake Away actually had far _more_ mouse-traffic than the one without. Since I only ran the experiment for four days, I'll say that this imbalance was probably due to random variation, rather than due to this product actually attracting mice. However, it's abundantly clear that it does not _repel_ mice in the slightest degree.Illustrations:Figure 1 shows the mouse tracks from the box with the Shake Away packet.Figure 2 shows the mouse tracks from the box without the Shake Away packet.Figure 3 shows the experimental setup for the box with the Shake Away, with the top of the box open. Note the stamp pad at bottom and the Shake Away packet hanging in the upper right corner of the box. The box is shown open here, but was closed for the experiment to contain and concentrate the smell of the repellent and also to make the box an inviting area for mice to explore.Additional Note:I ran an experiment like this one with  Victor "Scent-Away"  -- a similar product that uses pure peppermint oil. Since I got negative results with that experiment, and since this Shake Away product seems to use peppermint as its primary active ingredient, I wasn't surprised that this product didn't work either. In my review of the Scent-Away product, the manufacturer left a comment making the excuse that peppermint has been "proven" to discourage mice from _nesting_ in a treated area. So if you have a problem with mice nesting in a certain spot (the engine compartment of a car, for example), this product might work for preventing that.But for simply repelling mice, for keeping them from doing all the destructive, annoying, and unsanitary things they do when not in their nests, this experiment clearly shows that this product does not work.
