Recently I've seen reports in the media about bed bugs. They seem to be becoming more frequent.
When you travel -- don't bring them home.
"The Bed Bug Registry is a free, public database of user-submitted bed bug reports from across the United States and Canada. Founded in 2006, the site has collected about 20,000 reports covering 12,000 locations."

Watch out for the North East and Florida.
