WDW controls the pests in the theme and water parks, and at the water resorts. You generally won't have any problems with mosquitos as long as you don't wander away from the paths and attractions.

Wow thanks for all the quick responses! I bet your right about doing slot to control the bugs themselves.
I have never had much of a problem in the world with those nasty things. But at home its another story.
