Once upon a time, yelling “fire” in a crowded theater was the recipe for a stampede. But as a New Yorker, I can attest that these days you could probably achieve the same result with a shout of “bedbug,” particularly since one highly trafficked Times Square movie theater was briefly closed in August to spray for the pests. Maybe theaters showing Piranha 3-D or Vampires Suck could spin a bedbug infestation as an enhancement of the cinema experience, but I don’t think any others could. Eh, maybe The Expendables, too, for different reasons.
The resurgence of bedbugs in U.S. cities has people spooked but, in the New York Times, Donald G. McNeil Jr. neatly transcends what he calls “the ick factor” long enough to write about two of the more interesting scientific questions about the outbreak: Why are bedbugs making a comeback now, decades after the use of pesticides that once controlled them stopped? And why are bedbugs, unlike so many other blood-drinking parasites of humans, apparently not vectors of disease?
Read on to learn more from McNeil about those subjects. I, instead, will point out two passages in the article that help to illustrate why you just have to love parasitologists.
Exhibit A (emphasis added):
…The classic bedbug strain that all newly caught bugs are compared against is a colony originally from Fort Dix, N.J., that a researcher kept alive for 30 years by letting it feed on him.
But Stephen A. Kells, a University of Minnesota entomologist, said he “prefers not to play with that risk.”
He feeds his bugs expired blood-bank blood through parafilm, which he describes as “waxy Saran Wrap.”
Coby Schal of North Carolina State said he formerly used condoms filled with rabbit blood, but switched to parafilm because his condom budget raised eyebrows with university auditors.
Oh, those university administrators. You can order a tank car full of rabbit blood and they don’t bat an eye, but you ask for one gross of condoms ribbed for the bedbugs’ pleasure….
Exhibit B, McNeil’s exchange with Mississippi State entomologist Jerome Goddard:
Well, he was asked — can you feel them bite?
“No,” he said. “If I put them on my arm and close my eyes, I never feel them. But I once got my children to put them on my face, and I did. Maybe there are more nerve endings.”
Why in the world, he was asked, would he ask kids to do that?
“Oh, you know,” he said. “Bug people are crazy.”
No, bug people. You are crazy wonderful.
