Although mosquitoes are generally worse in July, they can be a problem at any time throughout the summer and fall. Visitors to Gates of the Arctic and its associated communities should be prepared with more than one kind of mosquito protection.

Head nets, bug coats, long pants and assorted insect repellants are all good things to have with you for your trip into the Brooks Range. Head nets and bug coats often work best with a billed cap.
