The World’s Most Effective Mosquito Repellent

I know I am late to the party with this repellent. I regret not publishing it the at the beginning of mosquito season, but better late than never, right? This powder-based formula has been tested in mosquito hot spots such as New Orleans, the mangroves in Southern Nigeria, and in Philadelphia, where Asian Tiger mosquitoes have taken over. It works beautifully, and is like nothing else you have tried, even 98 percent DEET which can cause rashes. Please follow these guidelines:

  • Do not use on children because one of the ingredients, Mexican Mint Marigold can have psychoactive effects if ingested in large quantities.
  • Do not eat or smoke the powder (see the bullet point above)
  • For best results, grind fresh powder every 3 weeks or so. While older powder will work, it starts to lose its efficacy over time.
  • You can dust the powder directly on your skin, or over your clothes, though if you are wearing light colors, you might want to place the powder on the inside of them.
  • The ingredients can all be found online. Mexican Mint Marigold can be difficult to find, though. At the time of this writing, I located it on Etsy and E-bay.

an empty dusting powder decanter
2 oz. arrowroot powder
1 tablespoon dried Mexican mint marigold
1 tablespoon dried patchouli leaves
1 teaspoon dried lavender
1/2 teaspoon sweet flag
2 dried vanilla pods


  1. In a high-speed blender, place the arrowroot powder, Mexican mint marigold, patchouli, lavender, sweet flag, and vanilla pods.
  2. Blend on the highest setting for 3-4 cycles until all ingredients are ground to a fine powder.  Before opening the lid, tap it several times so the powder that it stuck to it will fall.
  3. Open the lid carefully because there will be a lot of dust.
  4. Using a tablespoon or a small scoop, fill the container. It is now ready to use.
