The best way of preventing the bed bug infestation is by keeping them away from the home. As you are travelling you should bring a flashlight and check the mattress. You should also look in the crevices and seams of the mattress. If you find dark blood stains over the mattress or the place you are going to be you must be cautious. If you find evidence of bed bugs then you must leave your luggage away so that insects cannot climb into it. It is also recommended to not leave any clothing or items on the floor where you feel bed bugs exist.
