Mosquitos? Ticks? Just wondering if I should pack bug spray.

In some of the very tropical areas, like Halawa Valley or in the rain forest, you will encounter mosquitoes, so insect repellent is strongly suggested. There are ticks, but they don’t seem to attack humans as much as they do the other mammals on the island. Our dog seems to attract ticks, but his monthly dose of Frontline keeps them to a minimum.
