My girlfriend and I wil be travelling to the Amazon in a few months and the topic of mosquito repllent has been brought up a few times. Mainly because bugs think she is a delectable buffet of human they can nibble on night and day. It's true. I have seen it with my own eyes, not a bug around and she is covered in bites while I remain unscathed. So we are wondering if there are any recommendations for excellent natural repellent that doesnt harm the enviornment?
