Your bed

Have you been on a trip recently? If so, you may have brought home some hitchhikers�of the creepy-crawly variety. Bedbugs, tiny bloodthirsty insects, are hosts to organisms that cause hepatitis B and Chagas disease, say health experts. But the real problem seems to be the infections and allergic reactions that can sometimes result from bedbug bites.

According to the Environmental Protection Agency, bedbugs are on the rise and becoming an increasing health problem. The insects, which hide in the crevices of mattresses and bedding, are showing up everywhere, from hostels to the swankiest hotels, and they often find their way into people's luggage, transporting themselves to unsuspecting homes.

What to do: If you've done some traveling recently, and especially if you've noticed any mysterious bug bites, wash everything in your luggage and consider scrubbing your suitcase with a stiff brush before giving it a good vacuuming.
