A quick google check:
Tripadvisor: "I have never seen as many mosquitos as I did along the Dempster Hwy - and I'm from Saskatchewan! We were there in July. August might be better, particularly late August when nights are cold enough to kill them off. If you have room for the gazebo, take it. We stayed at a campground along the Dempster where there was a screened-in cooking shelter. We would have been miserable without it. There were so many mosquitos that when we woke up in the morning, the tent's screen door was covered in them. Most people with RV's skip the sheltered campgrounds and park overnight in a windy roadside rest stop or gravel pit. Mosquitos weren't bad in either Whitehorse or Dawson City. "
Alaska Guides: "Mosquitoes are more than a nuisance in the summer in northern Alaska; they are a genuine problem. Be vigilant. Keep your windows rolled up, enter and exit the vehicle quickly and close the doors, or dozens of the little devils will enter in a minute. Donโt park near water for picnics or overnight, if possible. Beware of walking into the shade. Mosquitoes love the shade. Buy high-quality bug repellent and purchase mosquito coils, available in most general merchandise stores in Alaska. Burn a coil for 20 minutes while you are out of the vehicle; that will kill the mosquitoes. It doesnโt smell too good, though. Donโt become a mosquito dinette: wear a long-sleeved shirt and pants."
