I was Girl Scout for a number of years, but not until I had two sons of my own that were Boy Scouts, did I learn to use dryer sheets to keep mosquitoes away! It really works. I usually wipe it on any skin that's exposed, and then just stick it in a pocket!
Crushing a few leaves of the Mosquito Plant and rubbing them on your skin also works to repel mosquitoes! I have several large bushes growing back by the barn. It is very hardy, my kind of plant, and the foliage is pretty.

I did a little research and found that the Mosquito Plant is actually a genetically engineered geranium hybrid! Interesting ...
