The only place we ran into mosquitos was on the Chilkat river, on the bank before starting our float down the river to see eagles. The mosquitos there were very agressive. My wife used Avon "Skin so soft" and was not bitten. I used nothing and had welts still visible two weeks later... But the mosquitos were not around on the river or anywhere else. Except for that one location, bugs were not a problem, and if I'd used a bit of repellant, not even then. Have some repellant with you just in case, and enjoy your trip! --Bob
