We've been to WDW at various times of the year, Feb., May, Sept. Oct. and Dec. and we've never had a problem with insects at the parks. I think I've only seen a butterfly and maybe an ant or two but usually, we don't encounter any flying insects. Maybe I'm just not sweet enough but I would say you won't have a problem. As for the love bugs, I don't recall seeing those in the parks either. They will, however, plaster themselves all over you car and are acidic. If left on for any lenght of time, they can eat the finish of your car. I believe I'm stating this correctly. We drove from Orlando to Miami one September and the front of the vehicle was just covered with them, including the windshield. They're almost impossible to wash off without a lot of elbow grease. We drove our own van and we can still see little spots on the paint where they were. They only occure in the spring and fall, I believe. You should do ok in the parks. Have fun.
