I am planning some very long cycling and paddling trips this year – most of them will be in hardcore mosquito and tick country. I will be wearing hiking sandals (Keen Newport) all the time and wonder how I can protect my feet against mosquito bites and ticks.
Would it help to "impregnate" the sandals with Permethrin? The waterproof Keen sandals are basically out of plastic and I am worried Permethrin could melt the plastic. Also I wonder if Permethrin on plastic works as well as it does on clothes.
From what I read on other Permethrin threads on BPL this strategy will not protect me against mosquitoes, possibly only against ticks.
What do you do to protect your feet from mosquitoes? Wear permethrin impregnated socks? Use mosquito repellent directly on the skin? These two strategies would only work on the bike trip. While paddling I have to get in and out of the water with my bare feet in sandals many times that DEET will probably wash off quickly. Any other suggestions?
