Bed bugs (chinches) are a known but manageable presence on the Camino de Santiago. While they are not "common" in terms of affecting every pilgrim, they are a persistent reality due to the thousands of hikers moving between high-occupancy hostels (albergues) every day. Industry reports suggest that fewer than 5% of pilgrims actually encounter bed bugs during their journey, but the risk increases during the peak summer months when the trails are most crowded. Most albergues are hyper-vigilant, using plastic-covered mattresses and frequent professional heat treatments to prevent infestations. To protect yourself, it is recommended to use a silk liner or a chemically treated sleeping bag (permethrin-treated) and to avoid placing your backpack directly on or under the bed. If you do find bites (usually appearing in a "breakfast, lunch, and dinner" line), it is crucial to inform the hospitalero (hostel owner) immediately so they can fumigate the room and help you heat-treat your clothes to prevent carrying the bugs to the next village.
