The Thermacell holder has a couple of straps with a plastic clip that looks like it should wrap around your leg or arm or some such way. As Thermacells are said to work best when horizontal,I just clip the straps through a belt loop and let it hang (mostly horizontally) and it works great. Yup, it can get expensive, but personally, I think it's worth it. You just forget there are mosquitos around when you have one. And I second what Ray says about walking around. If you walk fast you probably don't need one anyhow. If you walk slowly/stalk/stop often they work just fine.
