I have read where these work great to keep the mosquitoes from eating you during bow season. Ran across them on Brickseek for $32 but once I searched our local stores...the Walmart in Yukon has them for $17. There were a couple left after I grabbed 2, all the models are stacked in 1 row so you have to dig a little.
