We look forward to hearing more about what happened in Arlington, Virginia these last two days, at the EPA National Bed Bug Summit.

This video from the Associated Press has some nice snippets from Dini Miller, Harold Harlan, and others, speaking at the conference.

Pete Grasso of the PMP blog liveblogged the bed bug summit.

Here are some tidbits from Grasso’s blog:

Tom Neltner, from the National Center for Healthy Housing said (4th update, 10 am):

“People who are the least able to afford extermination are at the highest risk for poor health outcomes as a result,” Neltner said. “This is a good time for Federal agencies to take a leadership role on this issue.”

Of Michael Potter, University of Kentucky entomologist (6th update, 10:37 am), Grasso says:

He questioned why bed bugs are not considered a public health concern, because they once were.

You know a few years back, I started the first unofficial Dr. Michael Potter fan club, don’t you?

I know you’ll want to read the rest of Pete Grasso’s account, which begins here. He also talks about the breakout brainstorming sessions here. Perhaps most exciting, the list of recommendations the brainstorming produced, which is in part three, here.

Many thanks to Pete Grasso of PMP for blogging the summit!

The popular media was going crazy the last few days, but most articles were just reprints of one from the Associated Press. Here’s the Today Show, which showed footage of Connor’s Pest in Virginia doing a thermal treatment and searching with a bed bug sniffing dog.

I am so glad this event happened, and I so wish I could have been there. (My job kept me away.)

Pest Management Professional’s articles are often so good, but in the past, you had to know to look for them. (Thank goodness they added an RSS feed so we can subscribe.)

Mark Sheperdigian brings the bed bug information in three “new to us” articles: the first is on what consumers need to know about bed bugs.

In short:

• They’re not microscopic. (Lou Sorkin always helpfully reminds us, and the authors of run-of-the-mill newspaper stories that bed bugs come in a range of sizes and colors depending on life stage and whether they’ve eaten or not (lovely, yes?)
• You can’t get an infestation from a single egg (though you can get one from a single pregnant female).
• You can’t clean them away.
• And you can’t prevent them.  (You can reduce the risk, but never 100%.)

You’ll want to read the rest of this article here.

The next article is about choosing pesticides, and is really for the bed bug pros among us, but is enlightening to us laypeople too.  In particular, the beginners’ guide to pyrethroids.  And neonicotinoids? New to me.

The choicest nugget here, though, was the suggestion that PCOs test a bed bug population as to its pyrethroid-resistance.  Simple, not foolproof by any means, but really smart:

If the bed bugs are resistant to pyrethroids, you should either know this going in or ensure that pyrethroids are not your main line of defense. How can you know if your bed bug population is resistant without having to send them to a researcher somewhere? You could try this procedure, which has been suggested from a number of sources:

At least a day before the treatment, collect some bed bugs and hold them overnight in a jar on a cloth or paper towel that has been treated (and dried) with your pyrethroid of choice. If all of the bed bugs are dead in the morning, you may fire when ready. If half the bed bugs are dead, be sure to incorporate other non-pyrethroid materials into your program. If the bed bugs are all alive, you should rethink your strategy — leaving pyrethroids out of the mix altogether.

This is not real science and will not lead to dramatic headlines that rock the pest management world, but it may help you avoid a follow-up treatment or two…or three.

Up until now, this might have only worked in large infestations, where “collecting a sample of bed bugs” is simple.  However, new bed bug monitors like the CDC 3000 will mean that even smaller infestations can be tested in this way.

Cool, huh?

(As always, I do not recommend you self-treat for bed bugs.  I am not a PCO but I think a good one is going to get rid of your problem more quickly and more fully than you ever will.  A good PCO will be able to do so safely and will know how to avoid making the problem worse.)

Finally, I found this PMP article enlightening.  In it, Sheperdigian pokes some holes in common theories about bed bug resurgence.

His point appears to be not so much that an end to baseboard spraying or the survival of bed bugs in chicken houses (for example) did not contribute to the resurgence of bed bugs, but that no one theory alone fully accounts for bed bugs’ reappearance, in such numbers, at this time, and their degree of pyrethroid resistance.

Read this one for the sub-headings alone.  (“Harlan hears a who?”  Priceless.) 

And know just how indebted we are to Dr. Harold Harlan, who kept his bed bug colony all those years before there seemed an obvious need for one.  And boy, do we ever need them as research subjects now.

Richard Shin reports for The Pioneer Press on research being done by Stephen Kells on bed bugs at the University of Minnesota.

Kells is at least one of the entomologists working on making an effective bed bug trap.

Alas, “we’re quite a distance off” from a monitoring trap, Kells said.

Eventually, it will be a wonderful invention.

It was interesting to hear how Kells got into bed bug research:

Kells first encountered a bedbug in about 2000 while working in the pest-control industry in Canada.

He dipped it into insecticide. The beast lived for four days and laid eggs.

“At that point, I knew we were in trouble,” he said.

Kells decided to study the insects further in an academic setting. He came to the University of Minnesota 3 1/2 years ago and set up a lab devoted to bedbug research.

About 2,000 bedbugs live there, housed in jars, where they crawl around pieces of filter paper that vibrate and twitch with their constant motion.

They eat Red Cross-donated human blood that’s beyond the expiration date, heated to body temperature.

Kells built a special platform he calls a bedbug arena, where he can observe the behavior of individuals when exposed to stimuli like heat. Part of his research is funded by the Propane Education Research Council, which wants to know whether propane-heaters can be used to kill the insects.

Another set of experiments involves attaching bedbug antennae to tiny electrical probes to see what kind of chemical compounds the antennae are tuned to receive. This might help develop the lure — maybe the carbon dioxide that sleeping humans exhale or the fatty acids on our skin — for a bedbug monitoring trap.

I am trying to envision the little tiny electrodes on the little tiny antennae. I also was fascinated by the bed bugs eating expired Red Cross blood, since all the other times we’ve read about researchers feeding their own bed bug colonies (as Lou Sorkin does) or having their grad students do it. I suppose it would be difficult to support 2,000 bed bugs.

The article also talks about the differences between captive bed bug colonies, and “wild” bed bugs, and it cites Harold Harlan, former Army entomologist (and author of the Armed Forces bed bug guide), as the source of Kells’ colony:

Bedbugs are a lot more resistant to poisons than they used to be. It takes 1,200 times the amount of insecticide to kill recently captured bedbugs than it takes to kill individuals from bedbug colonies that have been in captivity for more than 30 years, Kells said.

That captive colony was maintained by Harlan, who collected about 600 individuals from a barracks at Fort Dix, N.J., in the early 1970s. They were a novelty at the time, Harlan said. Over the years, he kept the colony alive in jars, letting it grow into the thousands, by allowing the bugs to feed on his legs.

“I’ve had them escape a few times in my house,” he said.

He had to leave the colony untended for a year when he was deployed in Vietnam and couldn’t find anyone willing to be a food source. When he came home, enough had survived to rebuild the population. Now his pets have become a resource for researchers.

I have a hunch this is where we got the information that bed bugs could survive, unfed, for a year. (We still aren’t sure where the “18 months” rule came from.)

Thanks to all the bed bug researchers, and universities, foundations and private companies that fund their work.
