NOW Essential Oils, Peppermint Oil, Invigorating Aromatherapy Scent, Steam Distilled, 100% Pure, Vegan, Child Resistant Cap, 4-Ounce

This is the best bang for your buck. I needed a large amount because I use peppermint oil for a lot of things but the main thing I use it for is as a rodent deterrent. I mix 10 drops in a spray bottle with water and spray my porch and under the hood of my Toyota (Toyota uses a lot based wiring insulation and the rodents are attracted to it). I also spray the currently used bath towels with this solution to keep the old towel smell at Bay. It works great as a fabric refresher and air freshener. This "now" brand peppermint oil says that it is not diluted and I believe it because it is strong. I will continue to buy this product as long as the price stays the same.

I bought this primarily to use as a hornet deterrent spray because I'm almost over-run with hornets and wasps as well as yellow jackets during the Summer months. I can say, with-out reservation: the quality is exceptionally good, the scent is natural, actual peppermint and so, not offencive to anyone. The potency is perfect as well. I'll certainly order more for the next season. And, if you enjoy the scent of peppermint, I would recommend this as an "aroma therapy" oil as well. As I say, the scent is "natural", fresh and clean.
