Can you recommend what to do to get rid of bedbugs before they start?

Bedbug prevention: Bed bugs can travel in your clothing packed in your luggage. If you visit a hotel or home with bedbug infestation, you can bring the bedbugs with you. Here is a website from the centers for disease control about bedbugs: http://www.Cdc.Gov/parasites/bedbugs/.

Bed bugs: If you have been in an area that was infested with bedbugs you will need to be quick on your feet. Wash clothing, linens, towels in hot water. Dry on highest heat - then repeat. Place clean items in a sealed bag to prevent re-infestation. Steam clean what you can't place in drier. Vacuum everything using a disposable bag. Seal bag & dispose of bag. May even need to throw away some luggage.
