i've been hammocking for 2 years now & i've never used a bug net. i guess there's been a time or two when it probably would have been helpful.
mostly little nat-like bugs that just irritate you, or pesky flys (man, those little devils can be persistent), but sometimes a few mosquitoes too.
no doubt, i've been fortunate w/ the places i've camped though.
if i were going to be out longer i think i would at least treat the hammock w/ permethrin & have something like hammock engineer's bug head net, if not a more full bug net of some kind. ...tim
