Alaska Mosquito Season

Q: What is the best time to visit alaska and avoid the mosquitos??
A: Generally speaking, mosquitos are not a problem in the urban communities such as Anchorage, Juneau, or Seward. You are more likely to run into mosquitos while on excursions, or in destinations such as Denali or other parks. The mosquito population tends to peak early and by mid-July and August they are less of a nuisance. Bring some bug repellent while enjoying the outdoors and you’ll be fine.

    “The mosquito population tends to peak early” What is early? This doesn’t really give me a very clear idea if my vacation in May will be impacted. Cruising lower half, Ketchican and points south.

    Linda, if you are cruising you don’t have too much to be concerned about as you’ll primarily be in coastal areas and on board. In towns such as Ketchikan and Juneau you don’t really get too far off the beaten paths and urban areas probably much like you would find at home in most of the United States.

    I am bringing a group of 50 people to Alaska June 12-18, 2016 and we will be in Anchorage and Denali. Will we have a problem with mosquitoes? I selected this time of year because I was told this was the shoulder season and mosquitoes would not be a problem.

    Joyce – Each year can vary when it comes to mosquitoes. In general, there are more mosquito early season than late but it really depends on the winter, how early our spring is, etc. Urban areas such as Anchorage won’t be bad. Denali could have some mosquito’s but assuming you aren’t going to be in the backcountry hiking you should be fine. Again, each year is different.

    Would last 2 weeks in August or first 2 weeks in SEPTEMBER be the best for lower mosquito numbers? I am very attractive to mosquitoes.

    Generally speaking, the later in the season the less mosquitos there will be.
