Where do they come from?

Travellers carry bed bugs around with them day in and day out, wherever they go; hotel rooms are particularly vulnerable given the high guest turnover rate. Moreover, it is not possible to screen the guests or prevent bed bugs from being brought into the rooms.
In most cases, the bed bugs found in infested areas such as hotels, hostels, motels - and more generally in all accommodation and collective residential facilities - hitchhike a ride in the luggage and clothing of those who unwittingly carry them to uninfected areas such as the home or hotel rooms.
Small and highly adaptable to variations in temperature, bed bugs are difficult to exterminate because they move rapidly, travel well and thus spread quickly.

If there is a host in the vicinity, a bed bug’s entire life cycle can run its course in 21 days; nevertheless, the average lifespan is 10 months although they can live up to a year and a half without feeding.
Bed bugs can also migrate from room to room through small passageways or cracks in the walls and floors, or through piping and ducts.
Their range of action is calculated at 3-6 metres.
