How a Leafy Folk Remedy Stopped Bedbugs in Their Tracks
NY Times ^ | 4/9/13 | Megan W. Szyndler and Catherine Loudon

Posted on 04/12/2013 8:50:30 PM PDT by LibWhacker

Generations of Eastern European housewives doing battle against bedbugs spread bean leaves around the floor of an infested room at night. In the morning, the leaves would be covered with bedbugs that had somehow been trapped there. The leaves, and the pests, were collected and burned — by the pound, in extreme infestations.

Now a group of American scientists is studying this bedbug-leaf interaction, with an eye to replicating nature’s Roach Motel.

A study published Wednesday in The Journal of the Royal Society Interface details the scientists’ quest, including their discovery of how the bugs get hooked on the leaves, how the scientists have tried to recreate these hooks synthetically and how their artificial hooks have proved to be less successful than the biological ones.

At first glance, the whole notion seems far-fetched, said Catherine Loudon, a biologist at the University of California, Irvine, who specializes in bedbug locomotion.

“If someone had suggested to me that impaling insects with little tiny hooks would be a valid form of pest control, I wouldn’t have given it credence,” she said in an interview. “You can think of lots of reasons why it wouldn’t work. That’s why it’s so amazing.”

But even though there is no indication that the bean leaves and the bedbugs evolved to work together, the leaves are fiendishly clever in exploiting the insects’ anatomy. Like the armor covering knights in medieval times, the bedbug’s exoskeleton has thinner areas where its legs flex and its tiny claws protrude — like the spot where a greave, or piece of leg armor, ends.

“The areas where they appear to be pierceable,” Dr. Loudon said, “are not the legs themselves. It’s where they bend, where it’s thin. That’s where they get pierced.”

That statement is misleading. Pesticide-resistance be damned. Bedbugs did not re-emerge as a problem until they banned DDT. We did this to ourselves.

"Isn’t this similar to what borax?? does to fleas?"

An excellent mange medicine is borax disolved in 3.0% hydrogen peroxide.

I've used it, it works.

Do yourself a favor and study up on bedbugs. Infestations have nothing whatsoever to do with the cleanliness of your house, and everything to do with the fact that they prey on warm blooded mammals.

Do YOURSELF a favor and study up on bedbugs and their vectors; then think about the numbers of people exposing a hotel room. Look up bedbug registries and notice the number of temporary lodging sites.

“Orthoboric acid, 64%”

Is that the stuff that has glass like sharp, angular structures to the individual grain shapes? Gets on the fleas and eviscerates them?

Yup. It’s so small it has no effect on people, but it rips fleas to shreds. I imagine it has the same effect on other small critters like bedbugs and mites.

Orthoboric acid? Is that a specialty product?

That is what the ORTHO Company re-names boric acid so they can retail it at 5X-10X cost.

NOT to be confused with diatomaceous earth (DT)

La Lydia got the point by noticing that the writer implied DDT becoming ineffective which probably isn’t true at all, and at the same time concealing the fact that the probably effective DDT was banned, rather than becoming ineffective.

To me this is very effective and talented propaganda writing, it is ‘as smooth as butter’ writing.

“”But the commercial availability of pesticides like DDT in the 1940s temporarily halted the legions of biting bugs. As their pesticide-resistant descendants began to multiply from Manhattan to Moscow, though,””

One of the places to pick up bedbugs these days in film theatres, dogs go through each week to find bedbugs.

Bedbugs may come from filth but they are carried by people who are not filthy but who do things like put their purse down in a theatre

Interesting, thanks. I’ve used boric acid on ants and cockroaches in the past. Very effective stuff. Cheap, too. I bought a one pound container at the drug store when I was in college and the cockroaches in my student-housing “pad” disappeared after only one application. Kept that stuff waaaaay past its expiration date and would use it whenever I saw ants (luckily, never had cockroaches again after I got out of student housing). Finally threw the bottle out after 20 years and hadn’t even used a fourth of it.

Amen. I was going to say libs are trying to turn us into a bunch of doggone bedbug trappers (until bedbugs become an endangered species, no doubt, at which time they'll demand protection for them). But I knew someone else would say it more succinctly.

Give me DDT any day of the week, or a chemical equivalent. I've got better things to do with my time than laying out bean leaves every day, or its chemical equivalent.

Note, too, DDT did actually solve the problem in this country once. Bean leaves never did that in Europe. But that's what these jokers want us to place our bets on. No, thanks, bean leaf jokers!

Amazing they actually impale the claw-like foot on a bedbug. Must be some pretty stiff hairs on those leaves. Either that or the bedbug's foot isn't a hard claw at all, despite appearances, but has the consistency of tofu or something.

I've read that tip before (about placing your luggage on a rack, or even in the bathtub), when you first go into a hotel room. Then you are supposed to exam the room carefully and if you see any sign of bedbug infestation, do not pass go, do not collect $200, but get the heck outta there!

Then I read someplace else that you can forget about that tip, because your luggage can pick up the beginnings of a bedbug infestation from contact (even if it's only secondary contact) with other luggage in the airport, or on a plane, or in the trunk of a taxi. Very discouraging.

Actually “filth” isn’t requisite. The bugs hitch-hike readily. 4-star hotels, college dorm rooms, any where humans go after acquiring the adults on their luggage, foot wear, garments etc. can provide a new home.

Dogs (trained) are the most effective means to find infestation.

Even have knowledge of an infestation inside a lap top computer. Sixty minutes in a 175 degree oven worked well to stop that infestation from spreading. Computer was fine.

“Except for the Hobo spiders, which can hurt you in a big way.”

I hadn’t heard of Hobo spiders until a few months ago. Then someone I know was bitten by a Hobo spider and he has had three operations for the nerve damage he got from the bite, and he won’t know for a few months whether or not he will regain use of his left hand.

I haven’t seen many in the last few years.

About five years ago conditions were right for them, and I was seeing 2-3 per month.
Whatever the right conditions are, I’m not sure!

I think they are like a cousin (or closely related) to the brown recluse, which we DON’T have here.

Fortunately, they are quite non-aggressive. Wussies in the spider world!

Bed bugs have an unique scent. When you are a dog-EVERYTHING stinks uniquely.

A handler/trainer isolates/obtains the associated target. Then it is a matter of creating in the dog’s mind a ‘game’ that he scores points when he signals you (Sit, a bark, 3 legged stance like a pointing breed, etc.) whether the game depends on sight, sound or scent. Preferably you get to start the game—command it starts.

Dogs have instincts/traits that have been selected for (think of playing BALL with a Lab) and the training seeks to capitalize on, augment/expand, and communicate with the dog for a desired/directed outcome.

Its 2 way communication, listening to the hounds comes to mind. Watch a narco/explosive search dog....he sits hard and looks at the “quarry” when directed to ‘search’ or ‘find’ or released with an “OK”. A good handler tries to put his animal in target rich playing fields.

So-get a jar of bed bugs and carry on.....
