"Repel Mosquitoes with a Bubble Machine"
Mosquitoes don't like soap, so bubbles are a perfect way to keep them away. This is a much more fun and interactive method of mosquito-prevention than Citronella or Deet.
According to [the weblog] DIY Life, mosquitoes are repelled by soap solutions (hence their disdain for dryer sheets), and a bit of soap suds will do a good job of shooing them away... Some blogs recommend adding a bit of lemongrass oil to your bubble mixture for more powerful repelling.
