>"Hey David, can I ask you to elaborate a bit on 'site selection' for protection from bugs. I presume you stay away from water sources. Anything else you try to go for?"
Different David here, but,
Wind really keeps the mosquitos down. So I'd prefer a knoll over a depression. (Also, you can get cold air from radiant cooling collecting in a low spot and being up 100 feet in elevation avoids that, too). At home, lawns are great "defensible space" not only from forest fires, but from bugs. Mosquitos hang out on bushes, down in tussocks and in tall grass. A mowed lawn has essentially no mosquitos. Similarly, in the backcountry, avoid high, thick grass and bushy areas.
If you have a broader area over which to select your sites: Higher up the mountain is almost always better: away from standing water and ponds, rockier without bushes, cooler temperatures, more wind all help.
Seasonally, I like to get out in the Fall once we have some freezing nights. The first freezing night really knocks them down.
