Not being an expert in bugs, we did see some, did I say some? Billions! of bugs when going across the lake to MK. They covered every surface and we vowed to never again travel by boat at night, it's the monorail for us in the future. Don't know what the bugs were, they may have been mosquitos, but I'm not really sure.
Apart from that, not been bothered in 5 trips in August!
