No more good night. No more sleep tight.

Bed bugs are back, and their sole purpose is to crawl into your bed and nibble on you as you sleep (and not in the good way).

According to this article, entymologists and pest control experts report that infestations are rising dramatically throughout the country.

They blame their resurgence partly on — wait for it — the decreased use of certain pesticides. Today, exterminators spray conservatively, rather than saturating a room. And consumers demand less toxic chemicals.

In other words, bed bugs are exploiting our eco-friendliness.

Apparently, the tiny insects were common virtually wiped out after World War II, thanks to the widespread use of DDT. They don't carry blood-borne diseases, but they do feed exclusively on blood, leaving red welts and swelling.

In the past few years, bed bugs have been found at upscale hotels, hospitals, prviate schools, maternity wards, dorms and other places with multiple beds and high turnover. They seem to thrive equally well in filth or pristine beds with high-thread count sheets.

Because of their significant PR risk, anti-bed bug task forces are already in the works in Hawaii and New York. Most likely, pest control companies will then have license to kill them — with extreme prejudice.

The downside, of course, is a cloud of pesticides, making it truly impossible to rest easy with either of the alternatives.
