The solution for bedbugs: DDT

I soon as I saw that my daily hits on my bedbug posts were going up again, I thought: "I bet bedbugs are in the news again." They are. There was panic in a Times Square movie theater last night when they closed it because of bedbugs.

Malaria and bedbugs were eliminated in South Africa when I was a kid. Then DDT was banned and they made a comeback. The irony is that some of the pesticides that replaced it were more dangerous than DDT.

Bedbugs

I still get a lot of hits on a post that I did years ago about the increasing bedbug infestation.

From This Bedbug's Life:

Global travelers now bring in a steady supply from around the world, inconspicuously undeclared in checked bags and carry-on luggage. Today, bedbugs have been found in all 50 states, as well as Guam, Puerto Rico and American Samoa, and bedbug-related calls to pest control operators are escalating at a fantastic rate. From June 2009 to June 2010, there were more than 31,000 calls in New York City alone.

We reserve a special kind of enmity for bedbugs because, though humans generally do not like being anywhere other than at the pinnacle of a food chain, there is a particular horror associated with being consumed while relatively helpless, asleep in what should be the security of one’s own bed (or chair or couch). With bedbugs, it’s personal — unlike cockroaches, ants, silverfish and other vermin that are attracted to our possessions, bedbugs are after us. And they’re remarkably adept at circumventing our defenses: They not only attack while we sleep, but they also inject anesthetics, so as not to awaken us, and anticoagulants, so that in every 10-minute feeding they can suck in two to three times their weight in clot-free blood.

Bedbugs win neither praise for their sophisticated technique, nor very much respect for the fact that they don’t carry diseases, as most bloodsucking human ectoparasites do. Although their bites can cause unrelieved itchiness, bedbugs take only blood and leave no pathogens behind. In contrast, lice spread typhus; mosquitoes carry the viruses that cause yellow fever, dengue, encephalitis and West Nile disease; ticks transmit the Lyme disease bacterium; and fleas can bring the bacterium that causes plague.

But lack of involvement in spreading disease is hardly an endearing attribute. In fact, precious few aspects of bedbug biology are endearing. They don’t build their own houses or care for their young, and their sexual practices are bizarre even by insect standards: Because the female bedbug has no genital opening, the male inseminates her by using his hardened, sharpened genitalia to punch a hole through her abdomen. With no elaborate courtship ritual, males in a frenzied pursuit of sexual congress often blunder into and puncture the bodies of other males, occasionally inflicting fatal wounds.
