The problem with deet is that it has limited duration, and I really dislike
putting chemicals on my skin.  I prefer Permethrin because you only treat
your clothes once every 6 weeks.  However Deet is good for exposed skin such
as hands and face so it can be selectively used effectively in combination
with Permethrin:

Permethrin clothing treatments, when applied following Directions for Use,
have been determined to have "spatial repellency" against mosquitoes. This
means that mosquitoes will swarm around you, but not light on your treated
clothing and bite. Also use an EPA registered repellent, such as the Sawyer
microencapsulated Controlled Release 20-percent DEET, on all exposed skin
for further protection from biting and blood sucking mosquitoes. The
combination of Permethrin on clothing and DEET repellent on skin forms an
"Insect Repellent System." When used as directed on the EPA registered
labels, the Insect Repellent System will provide the best protection from
biting, blood sucking and disease carrying insects. A well known study
conducted by Tom Lillie, Carl Schreck and A. J. Rahe in Alaska in 1987,
showed 99.9-percent effectiveness against mosquitoes biting at a rate of
more than 1,100/hr. This protection is far greater than either a DEET based
insect repellent or Permethrin can achieve alone.
