This is turning out to be the summer of bed bugs. There have been numerous issues on the news of bed bug invasions throughout the US.
In researching bed bugs I found this website Bed Bug Reports. They give many good examples of how to check for bed bugs in hotels prior to going to sleep.
These little blood suckers get you when you are asleep and can live years between meals. They also can readily crawl in to your luggage over night. You then bring them home.
The list on www.bedbugreports.com, gives a list of complaints from users of the website along with a list of hotels, some very fancy where people have been bitten. They also have some pictures of bed bug bites which are pretty disgusting.
