The Bedbug Registry is an easy way to see if there are bed bug problems at hotels you may visit. This is a free, public database of bedbug sightings with about 20,000 bedbug reports, so you can check whether other travelers have encountered bedbugs at a hotel you plan to stay at.
There’s a new Bedbug Registry app ($2.99) that allows you to search for bedbug reports by location when planning travel in the U.S. and Canada. Users can also submit their own report.
And here is another similar source, BedBugReports, which was created specifically to warn travelers about hotels that have had bed bug reports.
