+1 on the thermacell not being good with movement or any wind. Just did the experiment last weekend with a friend - set the thermacell between our two lawn chairs - less than 1 ft apart. The northern MN mosquitoes, which are not particularly thick now - ignored it and still hung around, even landing on the leg closest to the thermacell.
As a forester who worked in swamps for almost 40 yrs, deet on the skin, permanone on the clothes, and a headnet if black flies are on the prowl.
