2009 is the year of the bed bug monitor. While some are thinking high-tech, it is also important to know that low-tech monitors are being improved.

This month, the CDC 3000 is starting to be used by PCOs and a few of the luckier people with bed bugs. The Nightwatch is also set to ship soon, we’re told. The devices cost in the $500 – $700 range, and so they really are not aimed at the consumer market. These active bed bug monitors use kairomones, CO2 and heat to attract bed bugs into the monitors, and then trap them.

But passive bed bug monitors are also evolving. Traditionally, we have had the glue trap, which really is not very useful at catching bed bugs. Think about it: they’re usually rectangular, and they just sit there. They sit there covered with a thick coating of goopy glue, and people commonly report waiting patiently and nabbing no bed bugs. There’s no easy way to surround the legs of your bed in glue traps.

Enter Susan McKnight, who has designed the Climbup ® Insect Interceptor, a passive bed bug monitoring tool which can be used in homes under the legs of bed frames, chairs, tables, and other furniture.

This is a tool for finding out whether you have bed bugs. It is not going to treat an infestation, but can help you determine if you have bed bugs, and when they are gone.

It looks simple, but seems quite clever: first, it has two wells: a center well and an outer pitfall. So you can actually tell from where the bed bug is caught whether it is coming onto the furniture or trying to exit from it. (The idea is they can’t hop over the wall in between. Neat, huh?)

This is a photo of bed bugs caught in the Climbup ®:

Those bed bugs in the middle were trying to get off the bed / chair / etc. and the others were trying to get onto it.

You can imagine how some treatment plans could be improved if PCOs could see whether the bed bugs were coming onto the bed, or leaving from it.

Think also of the woman who reacts to bed bug bites, whereas her children and husband don’t. This monitor may allow a much better determination of who is actually being bitten.

The directions found in this PDF on the Insect Interceptor website note:

Climbup ® insect interceptor is ready to use with center well and pitfall ring prelubricated with talc to form slick surface to prevent bed bug escape. The talc will not kill bed bugs. With repeated wipeouts and prolonged use, relubrication with talc is advised. OPTIONAL: To avoid handling of live bugs, a dust (e.g. diatomaceous earth) or nonrepellent liquid (e.g. soapy water, mineral oil) may be added to in center well and outer pitfall ring.

Some bedbuggers have long placed a bed bug-free mattress and frame on top of risers or inside of margarine tubs and filled these with diatomaceous earth or mineral oil in an attempt to keep bed bugs from getting into the bed. The moat of mineral oil in a cup around the bed legs can backfire if there are any bed bugs living in the bed, because they become trapped on the bed, and will keep biting you there.

The approach suggested on the Insect Interceptor site is not an entirely different idea, but in my opinion is theoretically a better one: this product is designed to trap live bed bugs and to show which direction they are traveling in, both of which would be very helpful, moreso than simply trying to avoid bed bug bites.

A Pest Control Operator could, as the directions also suggest, “Count bugs by developmental stage from each capture area to determine efficacy of control treatment.” A resident could simply count bed bugs, and know if they needed a follow-up treatment, or not.

Dr. Mike Merchant of Texas A&M wrote on his Insects in the City blog about a presentation by Dr. Changlu Wang at November’s Entomological Society of America conference in Reno. Wang tested the efficacy of various spray-based and dust-based IPM programs for bed bugs (using chlorfenapyr, diatomaceous earth and Climbup™ monitors). Merchant noted that:

The traps caught more bed bugs than were observed by the inspectors in all apartments. Another interesting observation was that 94% of the trapped bed bugs were in the outer bowl, indicating that they were off the bed. This shows the importance of treating off-bed locations when controlling bed bugs. These devices might be especially useful for clients with low budgets and a high motivation to help with the elimination program. Of course the effectiveness of the bowls depends on eliminating contact of the bed and bedding with the floor and walls.

I understand that Changlu Wang’s research will be published soon (and we’ll let you know when it is). In the meantime, you can download a brief but interesting PowerPoint of his presentation at the ESA in Reno, 11/2009 by clicking here.

The PowerPoint stresses the usefulness of the product for low-level infestations and where residents do not respond to bed bug bites. We are told that only “4 of 10 residents noticed bed bug bites,” and that while visual inspection detected an “average of 6.7 bed bugs per apartment,” the Climbup™ interceptor after being used for 7 days found an “average of 8.8 bed bugs per apartment.”

For this reason, it would not be a bad idea for everyone to have these under their beds and chairs, sofas, etc. Wang’s finding that only 40% of the residents had bed bug bites reminds us that everyone needs an early warning system that they have a bed bug infestation. Those receiving bed bug treatment need to know when bed bugs are gone.

My only concern is that this product might have to be used creatively to work for some — for example, people who have platform beds with broad bases, or big clunky sofas — I am not sure how the product would work with items of furniture which don’t really have “legs.”

The Insect Interceptor website states that Climbup ® Insect Interceptors can be obtained from Residex and Oldham Chemical (by PCOs only from those outlets, I assume). We also see that Bed Bug Central is selling these monitors to the public. I have not actually seen them yet, but the research sounds promising. We look forward to reading Wang’s research results and to hearing from people who have used the product.

Update 4/23/2009: This month’s issue of Pest Control Technology has an article by Changlu Wang, Timothy J. Gibb, and Gary W. Bennett detailing the study of the Climbup ® Interceptor. You can see the contents of the April PCT issue with a link to the article here.

Update 5/12/2009:

Climbup ® Interceptors are now available from NorthShore Care (enter code in ad below for free shipping) and other online retailers, as well as from Residex and Oldham Chemical. In New York City, you can get them from Standard Pest.

In reference to the Don’t Let the Bed Bugs Bite Act of 2008, Budget Travel asks, “Should taxpayers fund the war against bed bugs?” The Act, H.R. 6068, is now in consideration by the House Subcommittee on Commerce, Trade and Consumer Protection,and would primarily give states funding to inspect hotel rooms for bed bugs.

Meanwhile, the bill Dale Mallory is sponsoring in the Ohio House of Representatives, which would establish a hotline where Ohio residents could report bed bugs or get information about them, and would require the Dept. of Health to educate the public about bed bugs, is also getting coverage from Cleveland NBC affiliate WKYC and in Vindy.com.

H.B. 590 states,

The department of health shall make available on its web site information on the increasing incidences of bed bug (cimex lectularius) infestation and post notices that bed bugs are a public nuisance dangerous to public health.

You might protest that bed bugs are not a danger to public health, but then the World Health Organization includes bed bugs in its new book, The Public Health Significance of Urban Pests. (You can download a PDF on the right side of this page.) And the WHO not just includes bed bugs — as Renee reminds us in an analysis of the WHO study over on New York vs. Bed Bugs, a bed bug is on the cover, with a tick and a rat.

The WHO is concerned about the public health significance of bed bugs. Ohio, along with other states (and cities and countries) should be concerned too.Similar Posts:
