Bed bugs are found in a few places on the Camino. The bites are very characteristic as they are in lines, like landing lights! Can be very itchy. Bed bugs don't spread any diseases but are extremely difficult to eradicate from your house, so be careful when you get home: I washed all my clothes on a hot wash, put my sleeping bag in the freezer and sprayed my bag with bug spray. On the Camino if you are concerned, normal insect repellent keeps them off.
