keeping the bugs away while Rving

One f our favorite parks is on a lake. Avg daytime highs in the 70-80s.
Usually a bit of wind in the day keeps bugs at bay when the sun is out but in the evenings skeeters come acalling sometimes biting flies, Campfire or not.I had thought of box fans but they don't look great and you would have to put two facing the same way at opposite ends of the awning, perhaps two at each end one on top of the other.
Has anyone come up with a unique solution..other than loud fans?
