Something new to fear from bed bugs?

Conventional wisdom has been that bed bugs do NOT transmit diseases to humans. Humans merely got irritating bites.
Now that may change.


Hate insects? Afraid of germs? Researchers are reporting an alarming combination: bedbugs carrying a staph "superbug." Canadian scientists detected drug-resistant staph bacteria in bedbugs from three hospital patients from a downtrodden Vancouver neighborhood.
Bedbugs have not been known to spread disease, and there's no clear evidence that the five bedbugs found on the patients or their belongings had spread the MRSA germ they were carrying or a second less dangerous drug-resistant bacteria.
However, bedbugs can cause itching that can lead to excessive scratching. That can cause breaks in the skin that make people more susceptible to these germs, noted Dr. Marc Romney, one of the study's authors.
The study is small and very preliminary. "But it's an intriguing finding" that needs to be further researched, said Romney, medical microbiologist at St. Paul's Hospital in Vancouver.

**Separately, note BEDBUG DETECTION, MONITORING AND CONTROL TECHNIQUES [US published patent application 20110080255 ] with first claim:

An apparatus, comprising an attractant source configured to attract one or more insects and a housing member in which the attractant source is positioned, wherein the housing member is of a plug-in form with a plug member being structured to engage an electric socket and define a cantilever to support the housing member such that a space is positioned between the electric socket and a portion of the housing member extending transversely to the plug member when the plug member is engaged in the electric socket.

From the specification:

[0003] Recent data suggests bedbug infestations (Cimex species) of human domiciles are on the rise. At least 92 species have been identified globally, of which at least 16 species are in the North American continent. Generally, bedbugs are parasitic pests with its hosts including humans and various domesticated animals. It is believed that bedbug infestations are becoming more problematic now at least in part because long acting, residual insecticides are no longer being used to keep bedbug populations in check. In addition, increased international travel and insecticide resistance have made bedbug infestations spread and control with insecticides very difficult. In terms of scale, such infestations are of particular concern for hoteliers, cruise ships, trains, daycare facilities, and the like because of the business reputation risk posed by had press or bad reviews. Other problematic areas tend to include nursing homes, barracks, dorms, hospitals, and various other forms of high density housing. Nonetheless, single family homes can likewise be impacted adversely.

[0004] For many of these dwellings, the pervasive application of long acting insecticides by spraying and/or dusting is undesirable. As a result, new approaches to bedbug detection, monitoring, and control are being sought. The present application provides contributions along these lines that are not only applicable to bedbugs, but may also find application in the detection, monitoring and control of other species of insects.
