They are bad depending on the wind. If it's from the north, no problem, that keeps the bugs away. When it switches around to the south, the bugs are pushed out and hungry!
It's not mosquitoes, its the flies (some small, some large) and gnats (very small). The flies actually remove flesh, and the gnats like to crawl into your eyes, ears, nose and mouth.
Bug spray does not work against either really, the flies ignore it, even 100% deet. The gnats, well, spray is somewhat effective? I can tolerate it on my ears and a bit on my forehead, but the strong stuff tends to feel like burning on my skin after a while.
Long pants and sleeved shirts, light gloves and a bug net are the best defense. I still have scars on my legs from when I decided to hike around in the woods wearing shorts because it was 90 degrees.
