We don't have any tips that are completely foolproof, but you can stack the odds in your favor. Before you leave, check the online ratings of the hotel where you plan to stay. People who have found bedbugs in a hotel room usually complain about them.
Don't set your luggage on the floor, the bed or upholstered furniture. Use the luggage rack, and pull it away from the wall. Don't unpack into the drawers if you can avoid it. Keep your suitcase closed.
When you pack to go home, inspect your luggage and your clothing. If you are not sure about an item, seal it in a plastic bag so that it can be washed in hot water or run through a hot dryer. Things that can't be washed should be dry-cleaned. A homemade bedbug detector developed by scientists at Rutgers University is described on our website (www.peoplespharmacy.com).
