On my recent Camino Portuguese a pilgrim I met had some nasty bites, mostly on her legs. I suggested they were bed bugs but the hospitalero (in a private albergue in Pontevedra) said they were spider bites. They did not have the little blisters nor did they itch. However they were in the the row/clusters that I have experienced with bed bugs. She did treat her belongings. I'd not heard of spider bites in Spain. Is this something to watch out for?
