The mosquito—contrary to popular belief—is not Alaska ’s state bird. But skeeters are nearly as much a symbol of the Great North as glaciers, totem poles, and the aurora borealis. Mosquito eggs hatch in water, so the boggy, muskegy, marshy forests and tundra, plus all the ponds, lakes, creeks, sloughs, and braided rivers of Alaska, provide the ideal habitat for these bothersome creatures. Alaska hosts around three dozen varieties of mosquitoes.
Mosquitoes hibernate in the winter and emerge starting in March–April. Peak season is late June–early July. The males don’t alight or bite, but they do buzz around people’s eyes, noses, and ears, which can be as annoying, if not more so, than the bites. The males live 6–8 weeks, feeding on plant juices; their sole purpose in life is to fertilize the eggs the females produce. They also feed birds and larger insects.
The females live long lives producing batches of eggs, up to 500 at a time. To nourish the eggs they feed on the blood of mammals, using a piercing and sucking mouth tube. The tube also injects an anticoagulant, which causes the itch and swelling from a bite. No Alaskan mosquitoes carry the diseases that tropical mosquitoes are known to, such as malaria, yellow fever, encephalitis, and elephantiasis.
Mosquitoes are most active at dawn and dusk. Windy conditions and low temperatures depress mosquito feeding and breeding. Mosquitoes are attracted to dark colors, carbon dioxide, warmth, and moisture. Mosquito repellent containing DEET (diethyl-meta-toluamide) is the most effective. A head net helps keep mosquitoes and other buggy critters away from your face and is a wise investment for anyone heading into remote parts of Interior Alaska  or Kodiak Island.
If you wear light-colored heavy clothing (the stinger can pierce light materials), camp in high and dry places that are apt to be breezy, and rub repellent on all exposed skin, you should be able to weather mosquito season without too much difficulty.
