For skeeters, I ordered one of these 'bee keeper like' hoodies: http://www.bugshirt.com/
I cannot stand having skeeters buzzing around my head. That drives me nuts. I also cannot handle too much bug spray on my head/ears/neck. My body reacts funny when I spray to those areas, which is probably a warning signal.
Those damn marsh skeeters are large, blood-thirsty, and tenacious. It's no fun to getting blanketed from head to toe by a swarm of them. I've never tested a Thermacell during one of those times and I wonder how effective a Thermocell would be when the skeeters are that thick and a breeze is blowing.
