They are among the unwelcome "fellow travelers" in the mountains: bed bugs are only 1 to 8 mm long and can be transmitted unnoticed from hut to hut via luggage, clothing, or equipment. Currently, the species is experiencing a real comeback – including in the huts of alpine clubs.
To minimize the spread of bed bugs, the Austrian Alpine Club (ÖAV), together with the Alpine Clubs in Germany and South Tyrol, is launching an information campaign on the topic.

Alpine Club: Education and early detection are crucial
For hut owners and the sections that own huts, bed bugs mean high costs and a great deal of effort – also because specialist companies have to be called in to combat them. The earlier an infestation is detected, the more targeted the treatment can be. In addition to experts, special sniffer dogs also help to detect the bedbugs.
To raise awareness across regions, the Austrian Alpine Club (ÖAV), together with Alpine clubs in Germany and South Tyrol, aims to destigmatize the issue. "We don't believe it's productive to single out individual affected huts for public shaming." An infestation can affect any accommodation establishment.“ explains Carolin Scharfenstein from the Huts and Trails department of the Austrian Alpine Club (ÖAV).
A conscious approach to the issue significantly contributes to raising guest awareness and better protecting cabins. Ignoring the problem of bedbugs is not a solution.
