In certain areas of the world, head nets may also be desirable.
Mosquitoes can bite through clothing only when it is worn tightly against
c. Chemical Repellents--DEET. The issue insect repellent contains 33 percent
DEET (diethyltoluamide) in a polymer cream. The repellent is effective against many
biting insects including Anopheles mosquitoes. The repellents should be carefully
applied over all exposed surfaces of the body except lips and eyes. Application should
extend to about one-half inch above the cuffs of the sleeves. Application should be
repeated every 4 to 6 hours.
d. Chemical Repellents--Permethrin. Permethrin is an insecticide that is used
to impregnate fabrics including the BDU uniform, bed nets, tent screens, and the outer
shells of sleeping bags. Permethrin has an extremely low toxicity for mammals
including man, but is highly effective against biting insects. Thoroughly saturate the
outer garments and allow them to dry thoroughly before wearing them. Permethrin
should not be applied to inner garments (underwear, T-shirts, and so forth.) or to the
inner lining of sleeping bags.
