I purchased this oil for 2 reasons. The first to rid myself of spiders, and the second to rid myself of mice. Living in Boise, even though it is a relatively large city, it is still surrounded by agriculture. This means we have many spiders and mice. While I keep a neat and tidy home, when the weather started to turn, I had mice coming in through .... who knows.... and trying to make my home theirs. I did a lot of research and learned that mice and spiders do not like the aroma of Peppermint and decided to give this product a try based on other's reviews. When it arrived yesterday, I mixed a small amount in a sprayer with water and sprayed my front deck (where the spiders like to gather), my front and back entries, inside cupboards and closets, and all 4 corners of each room. Not only does my home smell wonderful, but this morning I had NO new spider webs on the deck, but the mice were gone!! You ask how do I know the mice were gone... because I set out several kill free traps and they were all empty!Teatree. Is it aromatherapist this is the most powerful of all aromatherapy loyals being antifungal as well as the antibacterial this is not a fragrance to wear this is like medication if you have athletes foot mix it with 1 ounce of a carrier oil like sweet almond or olive oil and add 15 drops to the tea tree oil and dispense it in between your toes also very good for eczema and Daphne use with cautionIt's my first time using essential oils and I can't tell if it's therapeutic or not. But it smells good. I'm using it with my Levoit humidifier. Warning: the Levoit instructions say "add 10- 15 drops of essential oil... etc". At first I tried 10 drops and I have to discharge all the water. It was too much, the smell was too strong. For the humidifier I'd say maximum 5 drops.Several years ago, I sold a major brand of essential oils, also using them daily. The brand I sold, absolutely does not compare to this brand. This Handcraft brand is amazing, pure, great quality. I am so glad I took a chance and made a purchase. I'm hooked, and have found my new go-to for essential oils.There are TONS of uses for Peppermints Oil. I purchased this product for the 3 below reasons and it has not failed. A little goes a long way but stock up anyway!1. it Smells Wonderful2. Seasonal Allergy Relief, Sinus Care and Respiratory Aid. I use this in my oil burners everywhere. I also like to put on a pot of water with a few drops and let it boil to get some moisture in the air. Also close the windows and turn on the air. Place a drop on a few cotton balls and put them in your air vents. This works wonders.3. Pest Control. Little critters and bugs hate the strong smell of peppermint. I put like 20 drops into a spray bottle with water and spray doors seals, window sills, patio furniture and storage containers, the trash can, EVERYTHING!! I put undiluted drops in the storage shed and our outside storage containers and we remain bug free!!Did you know that if you put like 30 drops of this stuff in a spray bottle along with water, you can spray this at a cockroach and it will die? I actually did it and it works. Plus it makes your home smell delicious at the same time. Then I bought Rosemary oil and I put 30 drops also in a spray bottle with water and I use that along the entrance areas to my home. Cockroaches will not cross rosemary oil because they hate the smell. It makes me think I should also have rosemary plants in pots all over the place.So Rosemary oil to keep them away, and eucalyptus oil if you want to kill them on contact. Oh and the smells are to die for.PS. I also heard that if you occasionally spray eucalyptus along the baseboards of your bedroom you're not likely to have any creepy crawlers nearby. I guess ants and other bugs hate the smell too. I sure am glad I like it.I went by other reviews and decided to try this for myself and I was not disappointed! When I first put this in my diffuser, my nasal passage got clear quickly but when I ran the ceiling fan... Wow! Even more effective!!This eucalyptus essential oil has a wonderful smell and really opened up my sinus. So glad I got the large bottle- I don’t want to run out of this! Delivery was amazing! Ordered in the morning and had in my hands the same afternoon.Diluted this with water and massage into the scalp for hair growth ?? Started to see a lot of new hair coming in within 3-4 weeksI have not tried the oil yet.I’ve used many different tea tree oils both with my skin care routine and for diffuser. This one is far the worst scent I’ve ever come across. DisgustingI always keep a bottle of tea tree oil, as it’s great for an antiseptic for any bites or abrasions.Can't fault the smell or the price. Will order again.
