I agree with falcon in that last post.
Just got back from the
Camino Frances in early November.
Bedbugs were present all along the Camino, and whenever I was able,
I reported them to the hospitaleros. Not all pilgrims will go to lengths
to find the hospitalero in the morning, as they usually are not around
as you prepare to leave, plus the pilgrim might be embarrassed,
but there should be a system in the albergue, like a chalkboard,
where a pilgrim could leave a message saying where they found bedbugs,
which bunk, etc. if they found nobody to report the bugs.
Near the end of my camino, a bunk mate in the private albergue (O Apalpador Albergue Turistico in Melide, adjacent to the municipal albergue there)
where we stayed was photographing a bedbug crawling across the floor.
I left there in a hurry and later that day spread everything in my pack out in a sunny field,
and shook the bejeezus out of every single item and let them sit in the sun some
more before repacking. My DH and I got not one bite, but met many who suffered
from bites.
I had protected everything I carried with permetherin, including my silk long underwear/pyjamas and my fleece hat, my boots, my pack, my sleeping bag and liner. We had not one bite, and I do think the permetherin treatment protected us several times.
When I got home, I left the packs and boots outside in the sun, and they stayed outside through several nights of hard frost before being brought in. All clothes and other items went into the hot wash.
