Bedbugs cause misery!

Put your suitcase in the tub, then check the mattress carefully for bugs. If you see anything that is suspicious move to a different room.

Pack all your clothes in ziplock bags. When you get home put everything directly into the dryer and nuke it. Then wash all the dirty clothes in the usual fashion.

Leave the suitcase out in the garage: do NOT bring it into the house, especially not into the bedroom. If you see any bugs you can slay individuals with rubbing alcohol (use a spray bottle), and prepare for an expensive eradication. The only effective was is to use heat: the insecticides do not work.
