This month’s Olympic games have one Bismarck woman busier than ever.

Kari Warberg Block’s “Stay Away Mosquitoes” patches are being given to athletes competing at the Games in Brazil.

“The patch is such a great option for the athletes. They don’t want to spray chemicals on their skin,” explains Kari.

The “Stay Away Mosquitoes” patches look like a Band-Aid and stick on your clothes. Kari says you can wear two to six at a time, depending on your size. They’re made from lemon eucalyptus and citronella. Lemon eucalyptus is a CDC approved mosquito repellant and parallels DEET in effectiveness.

“The lemon eucalyptus creates a vapor and the mosquitoes can’t smell the body’s CO2, which is what attracts mosquitoes to humans,” she says. “The patches are good for up to six hours and will be the only repellent patch to meet federal EPA standards for public risk mosquitoes and use by children and pregnant women.”

Kari has been working on developing this patch for the past two years, but this project was pushed to the top of her to-do list when it caught the attention of Olympic officials. She is also working to provide the patches free to refugees, through a percentage of the sales.
