Every camping group seems to have one person who mosquitoes don't bite. Why? Researcher James Logan James Logan is the name of:
  • James Logan (statesman) (1674–1751), colonial American statesman.
  • James Logan (author), Scottish author, wrote Scottish Gael (1831), list of clan tartans
 says it's because the person stinks--at least to the bloodsuckers.

Logan, a scientist at England's Rothamsted Research, collected human-emitted chemicals by wrapping volunteers in special foil bags. He then tested the chemicals' attractiveness to mosquitoes. The findings: Some people produced chemicals that the biting insects avoided. One possible reason the mosquitoes stayed back? The compound's scent may mask other more-attractive odors Odors

anosmia

Medicine. the absence of the sense of smell; olfactory anesthesia. Also called anosphrasia. — anosmic, adj.

halitosis

bad breath; an unpleasant odor emanating from the mouth.
.

What next? Logan hopes to incorporate the unattractive compounds into a new mosquito repellent re·pel·lent
adj.
Capable of driving off or repelling.

n.
A substance used to drive off or keep away insects.



repellent

able to repel or drive off; also, an agent that repels. Refers usually to insect repellent.
. For now, you can stick with bug-attracting friends--hungry skeeters are more likely to munch munch - To transform information in a serial fashion, often requiring large amounts of computation. To trace down a data structure. Related to crunch and nearly synonymous with grovel, but connotes less pain.

Often confused with mung.
 on them instead of on you.
