Bedbugs in Hotels

Many news reports in recent years have focused on the discovery of bedbugs in even upscale hotels, and a number of lawsuits have been filed by guests in these fashionable hotels who awoke to find hundreds of bedbug bites covering their skin. Searching on travel-review web sites regularly reveals information and even photos confirming the presence of bedbugs in numerous hotels.

Since bedbugs can arrive on the clothing or in the suitcases of guests from infested homes or other hotels harboring the pests, hotels can be an easy target for bedbug infestations.

What are bedbugs?

Bedbugs are parasites (insects) that survive by feeding on blood from humans. They are small, brownish-colored, and live in furniture cracks, beds (especially the mattress, box springs, and other structures such as the bed frame) but also can be found in travelers' suitcases and other items. Their highest concentration is usually within about 8 feet of a location where people sleep. They are active (seek a blood meal) at nighttime and just before dawn; they usually bite any exposed area of the skin (for example, the arms, hands, neck, and face). The bite is usually painless, but eventually multiple bite sites resemble a rash and become itchy. Bedbugs are not known to readily transmit other diseases, although a few investigators suggest that rarely, hepatitis B and/or Chagas disease may use bedbugs as a vector for these diseases.

Are bedbugs contagious?

Bedbugs are not contagious in the sense that they live on people and are transmitted directly from person to person. What happens is that bedbugs utilize humans for a blood meal and then leave the person's body. It seems like bedbugs may be contagious because they can live in some people's clothing, bedding, and furniture. These items, when utilized or transported during travel, can contain bedbugs waiting to encounter another warm body for a blood meal. Most experts suggest that the main hosts for bedbugs are humans and indicate that pets like dogs and cats usually are not bitten (not all experts agree on this); however, bedding material used for pets may serve as a site for bedbugs especially if the pet bed is located close to bedding used by pet owners.

How do I know if I have bedbugs?

Sometimes it is difficult to tell if a person has been bitten by bedbugs. Because the insects leave the person's body after a bite, and bites usually occur when a person is sleeping, many people do not know how they got this "itchy rash." In most instances, there are no lab tests used to detect bedbugs; however, simply using a magnifying glass while examining items such as mattresses or clothing (especially the seams in mattresses and cracks in furniture) for bedbugs, their eggs, or droppings is usually the quickest and best way to determine a bedbug infestation.
