Ah, the great outdoors – the sun is shining, birds are singing, and you’re free to enjoy it all – when suddenly you hear that dreaded “bzzz.” The fear of being covered in agonizing bug bites can get even some of the most health-conscious people slather on mainstream bug sprays. It’s smart to be cautious, as mosquitoes and ticks bear more risk than simple irritation or itchiness. They can transmit diseases like Lyme and West Nile Virus. Malaria, for instance, is responsible for over500,000 deaths a year.
