I have scent that keeps cats off my borders. It makes sense to me as it contains a scent that cats cannot stand, but a scent that gets rid of mice, wasps and spiders? All of them? A hybrid creature, the Mousewaspider? The three things are very different. I think they must all have a mutual dislike of mint as that is what this smells like. We have used it around the garage and there have been no new mice to our knowledge. I am not sure how much this is the spray.It is simple enough to use. You have to add a few drops to water as it is concentrated. This means that the small bottle goes a decent way. The only real issue is that I am not sure how effective it has been, but nothing else it has reassured my family that we are at least trying to do something about the mice.
