Some of us ring our dinner bell louder than others because we have a mouth watering combination of the above signals. The key to DEET-free outdoor living is to eliminate or disguise as many of those signals as possible and to confound Mosquito over the rest. Mosquito can fly only eight m.p.h., so it doesn't take much to waft her away. A 50 yard dash will leave the swarm lost and confused. Repeat as necessary.
Mosquito dehydrates easily and so seeks shade and low areas where the humidity is higher.
If all else fails, climb a tree or perch atop a rock. White masks your silhouette out in the open. Red flags her in also, as well as other insects. Air out outdoor clothing so that it does not harbor attractive odors. Drape a fern frond, long hair or something similar over head and face.
