Its camo because Home Depot is marketing it as a hunting accessory.
The dialog states that it works well on boats also.
I'll pay the expense if in fact it works. Here we don't get a whole lot of no see ems. Occasionaly is all.
We get the giant black flies. Nasty as well and you can definitely see em.
How much are the refills? I did not find that info on the page.
