Here's a effective mosquito repellant that you just stick on your arm three to four hours before you go where there might be mosquitoes. Each patch gives you up to 36 hours of protection.

The patch is a unique, safe and natural way to repel mosquitoes, gnats and flies.
There are no chemicals, pesticides or insecticides in the patch. It contains 300 mg. of Vitamin Thiamin B1. Our bodies generally absorb between 50 mg to 75 mg of Vitamin B1. The excess is displaced through our sweat glands. Research has shown that mosquitoes, gnats and flies do not like the smell of Vitamin B1 excreted through the sweat glands.

Mosquito Repellant

Studies suggest that taking large doses of thiamin is effective in reducing mosquito bites. This safe vitamin apparently produces a skin odor that is not detectable by humans, but is disagreeable to pregnant

All natural 36-hour mosquito protection patch is the easy natural way to keep mosquitoes away.
