Two part thread: (1) I was wondering whether anybody has tried using permethrin tick spray on their waders. Would it cause any problems to breathable wader material? They say it lasts up to something like 40 washes, so I'm also wondering how well/long it stands up on waders being submerged for a better part of a day, several days in a row. (2) Thermacells supposedly work wonders, my waterfowling buddies swear by them during early teal (I don't use one during early teal, and get eaten alive). I have never used one, but I just ordered one (the small one that you can clip on if you buy the holster), and was wondering whether anybody uses them while wading, and if so, how do you go about wearing it? I'd imagine if it took a dunk it wouldn't be very good. My thoughts were to clip it on the backside of my waders or backside of my chest pack.... Thoughts on either question? Thanks.
