You are stunned to see bed bugs in your suitcase when you open them at your hotel. Unfortunately, the previous owner of your booked room has bought you bed bugs while his traveling to other locations.
The longer you wait the greater chance the bed bugs will get out of your suitcase and find a new place to hide. This hiding spot will most likely be around your bed area. And this is how bed bugs spread from person to person. Tough you were not carrying the bed bugs while you started your journey but because of your previous hotel room owner now you got them into your house.
Not just by hotel rooms but bed bugs can spread into flights, trains, taxi cabs, or any other location traveling where general public occupancy is included. Bed bugs can also spread from beds or seats in a hotel room, taxis, flights & trains.
