Bests & Worsts Reviews from Amazon

Use your brain when using products. Rodents hate the smell of peppermint oil and cinnamon oil. Which this product uses, albeit less concentrations that I'd like but the price makes up for that and you can always add more on your own. It doesn't take much, really. The sprayer is battery operated which is useful I suppose. You don't need to use a lot of this. Just wet the area evenly, only 3 inches wide really. If it rains you'll have to reapply, obviously. This is a BARRIER product. It PUSHES rodents. It doesn't repel like an electric fence. If you already have an infestation this product will likely PUSH them inside more. You need to use this BEFORE you have an infestation. I use it in the fall right when the night temperatures get 40 or below. I spray the house brick where they likely come in under the siding. This worked so well that even squirrels that would bury nuts around my house stopped going there. I also spray my garage perimeter but I start inside around the cars for a week or two, since rodents are inevitably already inside. I then PUSH them out from there, after the car perimeter I put it on the INSIDE perimeter of garage walls. Then after a week I do the OUTSIDE perimeter. This works perfectly every single year. Once it stays cold they don't go inside because they already made their home for the winter elsewhere. But I do spray every other month or so to keep them out since for some people/mice they will be attracted back in the garage once the warm cars park in there. If you park outside where mice are a worry, spray under the engine bay ground and a perimeter around the car, preferably under slightly to protect from weather washing it away faster. They're attracted to the heat so they come in the engine compartment area the most. It's simple. Peppermint oil alone works but cinnamon helps. If you have rodents used to this or larger ones like rats you'll need to increase the oils. Buy some and add it to this, even cooking extracts work. You want toothpaste in your eyes or nose? That's what this does to rodents. But it PUSHES them. So if they're inside already you need to use it inside to PUSH them out (not advised since it smells ok but it'll bother your own eyes inside). This works best if you use it BEFORE but I promise once I had mice come in my house for two years straight it stopped after I used peppermint oil and cinnamon oil products. This is a weaker and cheaper product but it does work in principle. If it isn't PUSHING for you, get a product with higher concentrations or add more oil to this yourself. And remember, if they're already inside something you have to PUSH them from the inside first. You do it from the outside you're just going to keep them inside and they'll eventually get used to it anyway.
