Researchers Develop New Trap To Capture Bloodsucking Bed Bugs 141
Hugh Pickens DOT Com writes "Bedbugs (Cimex lectularius) are small blood-sucking insects that can live in cracks and crevices in and around your bed and crawl out at night to bite your exposed skin and feed on your blood, just as mosquitoes do. Now BBC reports that researchers from the Rutgers University Department of Entomology have developed a new trap that has a 77% probability of capturing bed bugs, nearly three times as many bed bugs over 28 days (PDF), as the the Climbup insect interceptor trap, which the authors cite as the best monitor on the market. A better trap design can allow people to detect bed bugs while they are still in small numbers. 'If you have only 10 or 20 bugs in your apartment, it's very hard to see with your eyes,' says Lead author Narinderpal Singh. 'When people realize they have bed bugs they are often already in their thousands, or hundred thousands. It's relatively easy to eradicate the bed bugs when they are in small numbers, but when they are everywhere, it's very hard to eradicate them.' The device can be created at home very cheaply and consists of a plastic dog bowl that's been inverted, with the outer wall covered with a layer of dyed-black surgical tape. The researchers contend that higher walls make their trap more effective than the interceptor trap because it's harder for bugs to escape."

I have occasionally wondered about using some variation on "phage therapy" for this. As I understand the protocols, the basic outline is:
1. Breed target organism (originally bacteria infecting a patient)
2. Sample natural water, and filter it with a ceramic filter to leave behind only phages as biological material.
3. Apply samples of phage water to target organisms, watch for signs of infection and death
4. If reliable agent is found, use dead targets to make more and isolate a workable phage
5. if reliable agent not found, goto step 2.
There are a lot of viruses out there.... I would bet something infects bedbugs and kills them effectively, and just needs a little help finding them.

a new trap that has a 77% probability of capturing bed bugs
Well, what does that mean? If I have bedbugs, and I leave this out overnight, is there a 23% chance it'll be empty in the morning? Will it capture 77% of the total number of bugs? Over what time period? And so on...
The BBC article is a bit less vague:
In a laboratory setting, they found that their trap had a 77% probability of capturing bed bugs released, whereas the shallower trap only had a 23% probability.
Although this too could use a rewrite. Does it mean 77% of all the bugs were caught by the new trap, and 23% by the old? Makes sense, given that the probabilities add up to 100% (and the article's photo shows both traps in the test area at the same time). But if they are meant to be independent probabilities, then there's a 17.71% chance that any particular bug won't be caught at all*.

They actually did a pretty thorough job of testing them and various attractants in various levels, and have real numbers in the report.
To attempt to answer you question (which can't be answered 100% accurately because there were many scenarios tested and you and the summary didn't state which was referenced)... not all the bugs got caught; the bugs that did not get caught were generally inactive and lethargic (I'm guessing they were old, or not hungry, etc), so they didn't really count them; the new traps caught about 2.5 fold more bugs given the same lure (or lack thereof); tests were run in a variety of settings, including an arena made from a wooden door and several infested apartments while people were there.
Also, for those wondering, the new trap is:
* inverted plastic dog bowl (600ml volume, 18cm diameter, 6.4cm depth, from IKEA)
* outer wall of bowl was covered with a layer of paper surgical tape (caring international)
* tape was died black with Fiebing's Lether Dye (Tandy Leather Factory)
* Incide of bowls were coated with a light layer of fluoropolymer resin (Bio-Quip products, Rancho Dominguez, CA) to prevent the bugs from crawling out
And the best lure was:
* 150g yeast (Lesaffre Yeast Corp)
* 750g granulated cane sugar (U.S. Sugar Co. Inc)
* 3L water (40degree C)
Fill a plastic tub with the lure mixure, mix it up, put on a lid, and rest it on top of two traps.

The final nail in the coffin for them was going out and buying a clothes steamer, and steaming the mattress, boxspring, pillows, baseboards, and any other hiding spots in the bedroom. They have to be heated to a certain temperature (can't recall the exact temp at the moment) in order to kill the adults and eggs.

Question- Do you use a clothes dryer? They typically heat clothes to about 180 F or higher. Hot water heaters are usually set to 120 - 130 F, so unless the clothes washer has a booster heater that is the hottest the clothes in the washer will get. Why will the clothes dryer not kill bed bugs?

Bedbugs have nothing to do with hygiene. They live off blood and only blood, not dirt or mold or anything related to cleaning.
And there are always places to hide. An air or water bed is a good start, yes, although you can get the same effect by encasing your mattress in a bug-impermeable casing. But they can still live in the bedframe, the walls, nearby furniture, etc.
In fact, a quirk of bedbug biology makes it even worse. Bedbug sex is extremely painful for the female (the term is literally "traumatic

Ants, flies, cockroaches, dust mites, etc. are not bedbugs. Bedbugs are not drawn to filth. They might use trash strewn about as a hiding place, but "clean that mess up or you'll get bedbugs!" is just not true. Bedbugs are drawn to you, because you are their food source. They spread by hitchhiking on clothes, luggage, etc. from an infested area to an uninfested area. Hotels are prime breeding and distribution spots. Or, if you live in an apartment complex or building, they'll spread between the walls from apartment to apartment.
If you really want to avoid getting bedbugs, the best thing you can do isn't to keep your room meticulously clean. It's to put your clothes and luggage in the dryer as soon as you return home after spending a night in a hotel.

Not with the bugs in question.
Ever stay in a hotel? If so, than it's basically nothing but pure, dumb luck that saved you from bringing some of these critters home with you. And should that happen someday, it's highly unlikely that you would even notice them until they had already multiplied into a pretty well established population. And if you think that staying in upscale hotels will save you, I'd point out that the only place I've ever encountered these critters was in a high end suite at one of the m

I still dont see how a commercial disposable products can hold up against the ready supply of a biologically mass replicated alternative, like kidneybean leaves.
Even in an inner city, it is absurdly easy to grow beans. You can get a pound of dried kidney beans for a few bucks at the grociers, and in about 2 to 3 weeks, have a towering vine of bedbug snaring death ready to be used for bug control.
It's a mechanical method, since the tiny hairs on the bottoms of the leaves are just the right size and shape to

They might catch some, but bed bugs are attracted to CO2, heat, and various other chemicals. One of the linked articles actually mentions a story about a guy with an infestation who had put the legs of his bed in buckets of water to keep the bed bugs from crawling up the legs of the bed, as well as surrounding his bed with diatomaceous earth (which bed bugs typically won't cross, since it can clog the holes they breathe through), only to have the bed bugs crawl up onto the ceiling and then drop down on his bed from above, with the fecal trail going up the wall to prove that's what they were doing.
Really, the traps that they're creating are not designed to deal with an infestation. They're designed to alert you with a higher certainty to the presence of an infestation, since everything I've read seems to indicate that a bed bug infestation is not something that the typical consumer is capable of handling on their own.

I had the same problem. Here's where he failed:
The bugs have to get off the bed and get back to the wall to crawl up and drop down on you again. So, I took a bucket of diatomaceous earth and put maybe an 1/8" layer, 2" wide along the baseboards of my room, under the bed including a 6" buffer area outside of the bed silhouette, around the legs of the bed, and then between the mattresses, under the sheets, and finally 4-6" swatch along the edge of the bed on top of the sheets.

Also, I must caution the user. I used a paint mask, gloves, goggles, and a foam brush to apply the dust. I also probably inhaled, over time a lot. I had some respiratory issues and odd, random itching for up to a year after this treatment, but I can't be 100% sure it's related or was psychosomatic. YMMV.

You misheard. CO2 isn't a poison; it's an attractant. They track you down using your body heat and the CO2 you exhale, so many traps are baited with CO2 and/or some form of heater.
However, your idea is very similar to one that does work, which is baking them. Bedbugs are vulnerable to heat, and will die in a few hours at above 120-degF. Higher temps have shorter kill times, and steam kills them instantly.

I believe the GP was saying that you should replace the air in the bag with 100% CO2, suffocating them.
Re: (Score:2)
Vacuum isn't necessary. Just 100% CO2 in a cylinder on one end of the bag, and a one way valve on the other end of the bag. Release the CO2 slow enough that it has time to fully mix. When you've released 1 volume of CO2, the concentration of air is 50% normal. 2 volumes, 25%, 10 volumes 0.1%. That should be plenty low to suffocate anything.

You are overthinking the problem.
To get near 100% CO2 in the bag, just visit a grocier or gas station that sells dry ice, then, when you bag and vac the mattress, just pack the naked dry ice block in with the plastic, with said valve.
The vac just makes sure the ambient oxygen levels are low to begin with.
This doesn't solve the problem with the bugs being in places other than the mattress though. Like roaches, they infest walls and crawlspaces.

Some form of natural predator insect would be advantageous, in conjunction with mechanical removal methods, like the traps.
Depends on which infestation you prefer, as the bedbug's most common natural predator is the cockroach.
There's also the masked hunter [wikipedia.org], which actively hunts bedbugs and doesn't carry disease. But they're generally solitary (in my experience at least) and not common enough to make an impact on the bedbug population, unless you specifically bred them for it I guess. Also, they'll give you a nasty bite if you piss them off, and they get stuck in the same stickytraps you'd lay for the bedbugs (since they walk
