We will introduce how to make a very cheap and effective insect repellent spray! If you use this, mosquitoes will hardly come near you. There are so many other benefits that I highly recommend it! How do you make it? What are the ingredients? I will introduce the explanation and the actual homemade method along with my personal views! I bought the materials for the DIY insect repellent spray I made this time on Amazon! ・Ken-ei Pharmaceutical Peppermint Oil 20mL 298 yen (as of 5/9/2025) https://amzn.to/4d5LWPC More than 30% menthol! It's also cheap, so I highly recommend it. If you haven't tried it, start here! ・Liberty Life Peppermint Oil 200mL 1790 yen (as of 5/9/2025) https://amzn.to/3RWNzp9 It's a large capacity and the unit price is cheap, but the concentration is unknown. ・Sin Peppermint Oil 200mL 1780 yen (as of 5/9/2025) https://amzn.to/4jLktVU This is also a large size, but the concentration is unknown. ・Peppermint Crystals 100g 1150 yen (as of 5/9/2025) https://amzn.to/4jJi91F 100% menthol crystals, the unit price is thought to be the cheapest in terms of content! It can also be used in a solid form! ・Anhydrous Ethanol IP 400mL 1473 yen (as of 5/9/2025) https://amzn.to/44uuCBD I was surprised by the recent increase in the price of ethanol! 😭 -IPA (isopropyl alcohol) 1L 1326 yen (as of 2025/5/9) https://amzn.to/4d5un2a If you just want to dissolve it, you can use IPA, a DIY essential. It's cheaper than ethanol! (It is about twice as toxic as ethanol, so it is not recommended for use on the human body) -Rice oil 900g 811 yen (as of 2025/5/9) https://amzn.to/4dfvTz0 It goes very well with peppermint crystals! Of course, it can be used in cooking, and it's nutritious and crispy! You can also use other vegetable oils, olive oil, jojoba oil, etc. -Saratekuto Mist Rich Rich 200mL 714 yen (as of 2025/5/9) https://amzn.to/4m8hlF6 The high-concentration type with 30% active ingredient DEET was cheap! It is expected to have a strong insect repellent effect, but due to the toxicity of DEET, it is prohibited for use by children under 12 years old. Normal products have a DEET concentration of about 10%, so it may be possible to dilute it three times and use it!
