It’s amazing how much the Central Ohio Bed Bug Task Force has been able to accomplish without any significant funding. The latest example is this presentation from the recent Central Ohio Bed Bug Summit: Bed Bug Distribution through Greater Columbus, 2007 – 2009 (PowerPoint).

The task force presents data from calls received at Columbus Code Enforcement, the Franklin County Board of Health and also from a survey of pest management firms in the Columbus area (3 firms responded):

The bottom line:

No part of the metro area is bed bug free

And, not surprisingly:

Bed bug calls are straining the resources of CCE [Columbus Code Enforcement], FCBH [Franklin County Board of Health], and most social services agencies in our city

This type of data collection is essential and here it is properly contextualized. Very often bed bug statistics are misunderstood. Valuable indicators, but by no means the extent of the problem.

A small business owner writes to the mayor

by Renee Corea on December 14, 2009

in Bed Bug Task Force

A New York resident shared this letter.

November 24, 2009

Mayor Michael R. Bloomberg
City Hall
New York, New York 10007

RE: Bedbugs, Small (and Large) Business and New York City

Dear Mayor Bloomberg,

[...]; I am a filmmaker and small business owner [...] I am writing to urge you to find a way to begin to seriously combat the bedbug epidemic that is taking over New York City.

I do not have bedbugs in my current apartment but I did have a relatively small issue with them when I lived in Williamsburg five years ago. My wife and I beat them at that time, but not without a lot of time, effort and expense.

The reason I am writing now is that I have two employees that are experiencing bedbug infestations in their homes. Neither can come into to work while they’re dealing with the issue; both are spending considerable amounts of time and money to combat it. Obviously, their issues are now costing me time and money also because the projects they are assigned to will remain stopped for a week or more while each is out.

In addition, I have had to engage an exterminator for my office as a preventative measure and I’ve spent a considerable amount of my own time assisting my employees so that their problems don’t spread to the office and the others that work here (or to myself and my family.) These efforts will have to continue for the foreseeable future.

For some time, bedbugs have been more than a simple nuisance in New York City. I believe they now are on the verge of having a major impact on the economy as well, whether through stories like mine, diminished tourism (all of the hotels are infested) or other reasons associated with business productivity. I am considering relocation in part because I don’t feel like the city is dealing with this issue in a realistic or aggressive manner. We need to see more education, laws and a real plan to attack to combat what has become a modern-day scourge. I understand that even major corporations (and Bill Clinton himself) have had to spend considerable time and money to rid their offices of bedbug infestations. It only goes to reason that if this problem is not addressed in a major way very soon, many people and businesses will simply begin to leave.

Please let me (and the rest of New York) know how you plan to attack this problem.

Best regards,

[...]

For some people — I am given to understand — the whole bed bug experience is quickly and efficiently dispatched. For others, as you see, it can be a disruptive event of great significance. I’m not sure what the secret is — if I did I would share.

New York vs Bed Bugs doesn’t have an active letter writing campaign at the moment. (We did in the past.) Nevertheless, I will ask you again in the spring, when the bed bug advisory board’s report is due.

Old timey bed bug news

by Renee Corea on December 10, 2009

in History

Sometimes it is postulated that people were more tolerant of bed bugs in the past. And yet if you actually look what you find is quite resonant with what has been happening to us.

What follows is mostly from the remarkable Historic American Newspapers archive of The Library of Congress: Chronicling America.

(As you value your time, leave that link be!)

The Bedbug Special, 1905

I think this is the earliest mention of steam for bed bugs that I’ve come across, though I’m not entirely sure how it worked.

WAY FOR THE “BEDBUG SPECIAL”!

Union Pacific Sends Out Train to Exterminate Vermin

[By Telegraph to The Tribune]

Cheyenne, Wyo. Sept 3.—An extra train, called the “Bedbug Special,” has just been sent out by the Union Pacific to exterminate bedbugs and other vermin in the section houses along the road. It is equipped with steam hose, poisons and disinfectants. Steam from the engine will be used.

New-York Tribune, September 4, 1905

The only other reference I can find is a note in Popular Mechanics.

THE “BEDBUG” SPECIAL

Probably the only train in the world of its kind and name is now going over the main line and branches of the Union Pacific. It is equipped with all modern appliances for exterminating bugs and insects of all kinds, and will fumigate all the section houses on the system. Steam from the engine is carried to the car where it is mixed with poisons or disinfectants according to requirements, and the building sprayed inside and out by means of hose and suitable nozzles.

Popular Mechanics, November 1905

You think they actually ran steam hoses from the train to the station houses (where foremen and crew lived)?

The Prussian railways

How about treating infested cars? Check out the innovations that surely make modern methods mere reinventions:

SCIENTIFIC MISCELLANY – A Disinfecting Oven for Cars

Cars on the Prussian railways—especially those used for Russian traffic—are often infested with vermin, and a new process of the Julius Pintsch Co. has been adopted for destroying bedbugs, nits, and disease germs without removal of cushions or fittings and without injury to varnish or polish. A disinfecting cylinder of cast iron, 16 1/2 feet in inside diameter and long enough to inclose the car, is used. This is closed at the ends by cast iron heads, and is air-tight and capable of withstanding enormous pressure. The total weight is 297,000 pounds. The car is run into the cylinder, and the temperature is raised by live steam to 114 deg. to 122 deg., when the air is pumped out to a pressure of one-tenth of the normal, the heat being still maintained. Formalin vapor is then introduced. In a test of the plant, the thorough heating of the car required about five hours, rarefying the air took two hours, but disinfectin with formalin was a quick process. Bed bugs and nits were effectively destroyed. Vestibule and dining cars with ceilings, walls and floors that had become wet through were inclosed in the heated vacum for 24 hours, and were dried in a surprisingly thorough manner. Allowing 10 hours for the disinfection of a car, it is estimated that the total expense is $8.33, ot more than a tenth of the cost of the less complete cleansing by the old methods.

Amador Ledger (Jackson, Amador County, CA) April 22, 1910

A heat chamber and a very big one at that as early as 1910.

$8.33 in 1910 is about $194.73 in 2008 dollars.

Old timey bed bug lawsuits

Continuing our trains theme, why is this one not at all surprising:

BEDBUG POISON EXPLODED

Pullman Car Porter Wants Two Thousand Dollars—A Novel Suit.

Special to the Herald.

San Antonio, Texas, March 20.—Alleging that he was injured by the explosion of bedbug poison which he was applying to the mattresses of a Pullman sleeping car, Henry Caviness, a porter, filed suit yesterday in the 57th district court of San Antonio for two thousand dollars damages. He declares that he was not warned that the poison was not only deadly as a bath for the obnoxious insects, but that it was equally deadly as an explosive, so when he struck a match to light a cigarette, the stuff exploded and damaged him and the cigarette almost as much as the bedbugs.

Palestine Daily Herald (Palestine, TX) March 20, 1908

Landlord/tenant cases:

BUGS FIGURE IN DECISION

Colorado Judge Decides Bed Bugs Justify Damage Suit.

According to a dispatch to the Miami Metropolis from Denver, Colorado, Justice Carlon, of that city, has decided that money paid by a guest to a boarding house keeper for a room in which bed bugs exist must be refunded.

Sleerman Goodwin, of Denver, who paid $3.50 for a room at the boarding house of Mrs. Henry Hewett, sued her for $25. Goodwin alleged that he paid $3.50 for a room for himself and family and that during the night an army of bed bugs attacked them. Mrs. Hewett indignantly asserted that Goodwin carried the bugs into the house.

The precedent that a room frequented by bed bugs need not be paid for by an occupant is established.

The Pensacola Journal (Pensacola, FL) September 01, 1907

This 1880 case featured expert testimony:

THE LEGAL STATUS OF BED BUGS

Campbell O. Bishop appeared before Judge Thayer recently, and urged his motion for a new trial in the case of Peckham vs. Garvey. It will be remembered that the defendant, Dick Garvey, the railroad ticket agent, was sued by the landlord of a fashionable hash-house for a month’s board, and pleaded bed-bugs in bar. The room had been engaged for a month, but the lodger decamped the second day, because he went there to eat, and not to be eaten. He testified that the bed-bugs preyed upon him worse than a guilty conscience, and he could not sleep. The jury gave the landlord a verdict for half the amount claimed. Mr. Bishop argued that the instructions were erroneous and the verdict ought to be set aside. He cited a number of English authorities in support of his motion, and one or two of them seemed exactly in point. The law, as laid down on the other side of the water, is that when a man rents a furnished room the landlord guarantees that it is habitable and wholesome. If his slumbers are disturbed by bed-bugs, he has the right to abandon the premises without notice, and is not bound to pay any rent for the time he has tarried. A case was cited in which the witness gave full details of the manners and habits of English bed-bugs, which are supposed to belong to the same breed as the American insect. [...] An English expert stated that it was very difficult to exterminate a colony of these insects. [...]

I’ll say. An English expert?

Sad history of bed bug committees, etc.

FAIR DOCTORS RAP BEDBUGS

Wisconsin Association to Battle It and Other Insects

MILWAUKEE.—Bedbugs were solemnly denounced by the Wisconsin Medical Women’s Association in annual session here. Dr. Adeline Riddle of Oshkosh, president of the association, characterized the bedbug as one of the greatest enemies to public health. [...] The women doctors passed resolutions authorizing the appointment of a committee to confer with the state board of health with reference to a public educational campaign on flies, bedbugs and other germ carriers.

More tales of CIN-1: PBO and deltamethrin

by Renee Corea on December 7, 2009

in Research

CIN-1 is a strain of bed bugs maintained at the University of Kentucky—one imagines for the purposes of inquiry into the supernatural limits of its invincibility.

Its provenance is the beleaguered city of Cincinnati, c. 2005.

Cincinnati, the city where bed bugs are run over by cars.1

I am sure you have read about CIN-1 already; it’s the (let’s say villainous) star of numerous research articles out of the University of Kentucky. Indeed there are other pyrethroid resistant strains in the University of Kentucky lab, but with every new article I find myself thinking, what fresh adventures in death and survival, CIN-1?2

Romero, A., Potter, M.F. & Haynes, K.F., 2009. Evaluation of Piperonyl Butoxide as a Deltamethrin Synergist for Pyrethroid-Resistant Bed Bugs. Journal of Economic Entomology, 102, 2310-2315.  

This new study looks at the role of piperonyl butoxide (PBO) in improving the effectiveness of deltamethrin. To the extent that pyrethroids remain the principal class of chemicals used against pyrethroid-resistant bed bugs (that is essentially the difficult situation we are in), it becomes crucial to figure out what resistance management strategies may be useful.

Here we can look back at the explanation of the mechanisms of resistance we got from Alvaro Romero earlier this year:

Alvaro Romero: Insects and various other arthropods have the potential to reduce the toxic effect of pyrethroids by becoming insensitive to them (mechanism known as target site insensitivity), by limiting penetration of the insecticide through their cuticle (skin), or by breaking down the insecticides with enzymes before the chemicals reach their target. Some of these resistance mechanisms have already been recognized in bed bugs.

PBO is a pesticide synergist; it increases pyrethroid toxicity by inhibiting P450s, the enzymatic systems that may be responsible for the bed bug’s metabolism of pyrethroids.

However, if resistance is not due to P450-dependent metabolism as indicated by PBO synergism, then presumably other mechanisms of resistance would be operating:

The level of synergism of pyrethroids with PBO is greater when P450s are responsible for conferring insecticide resistance (Kasai et al. 1998, Wu et al. 1998). Synergism with PBO has been proposed to increase the efficacy of pyrethroids against bed bug infestations that are difficult to control. Nevertheless, currently there is no adequate evidence about the effectiveness of these mixtures against resistant bed bugs. In this study we show P450s mediated detoxification in deltamethrin-resistant bed bugs.

First of all, for CIN-1 bed bugs, dry residues of deltamethrin alone do not cause greater than 50% mortality.

In tests with technical-grade deltamethrin dry residues, CIN-1 bed bugs that were pre-treated with PBO saw their resistance ratio (RR = LC50 of resistant strain divided by LC50 of susceptible strain; LC50 = “concentration that kills 50% of individuals at 24 h”) decrease from >2,588 to 174. When they were topically treated with deltamethrin (this might be analogous to directly spraying bed bugs), the highest exposure dose killed 72.5% of the PBO-pre-treated bed bugs.

In tests with formulated deltamethrin (Suspend) plus PBO (Exponent) or synergized pyrethrins (Kicker):

The rate of mortality of bed bugs exposed to Suspend, measured by LT50 values, was much slower in CIN-1 (LT50 = 15.2 d) and WOR-1 [a deltamethrin-resistant bed bug strain from Worcester, MA-RC] (LT50 = 5.4 d) than in the susceptible strain Fort Dix (100% mortality after 5 h exposure; data not shown). [...] The mixture of Suspend and Kicker required 36% less time than Suspend alone to cause 50% mortality in CIN-1 (9.7 and 15.2 d, respectively) and 50% less time in WOR-1 (2.7 and 5.4 d) (Table 2); however, significant differences between the two treatments were observed only in WOR-1 (Table 3).

LT50 = time to kill 50% of the exposed bed bugs.

Here’s Table 3 showing the differences between treatments for CIN-1 were not significant:

comparison of Suspend treatments.png

So, what is going on that PBO does not significantly improve the performance of formulated deltamethrin?

Lack of enhancement of mortality with dry residues of deltamethrin by PBO against CIN-1, a pyrethroid-resistant strain, indicates that addition of PBO, either alone or in combination with pyrethrins, is not a comprehensive solution to deltamethrin resistance. Dry residues of piperonyl butoxide synergized-pyrethroid formulations might only be effective against susceptible bed bugs or against pyrethroid-resistant bed bugs in which P450s are primarily responsible for the detoxification of the insecticide. Presence of a kdr-like insensitivity or any other resistance mechanism that is not inhibited by PBO might limit the effectiveness of dry residues of synergized pyrethroids against resistant bed bugs.

I’ve stopped thinking about the sorry pesticide that is deltamethrin. Instead, I worry about whatever comes next.

  1. Don’t get offended, please, just some pot/kettle humor between Great American Bed Bug Cities. []
  2. We can review: we know that CIN-1 bed bugs will cross a deltamethrin barrier to feed, but will avoid resting on deltamethrin-treated surfaces — and yet if it’s an established harborage we’re talking about, it doesn’t much matter to them if it’s been treated with deltamethrin or not. Nonetheless, in spite of their extraordinary resistance to pyrethroids (and DDT, mais oui!), Tempo Dust will knock them out within 24 hours. And while we catalogue these CIN-1 features, let me remind you that there are reportedly two tested pyrethroid-resistant strains that can be killed by a 4-month-old dry residue of chlorfenapyr (which we already know they do not avoid). CIN-1, surely, no? Otherwise it wouldn’t really be anything to brag about. And that goes double for the reported Section 18-supporting propoxur trial. []

Toronto schools bed bug policy

by Renee Corea on December 5, 2009

in Toronto

The Toronto District School Board has published a bed bug procedure as a standard for all schools, outdoor education, child care and administrative facilities.

The policy provides for mandatory notification of “signs of bed bugs in any teaching area or work site” to the principal or site manager, whereupon:

(b) If signs of bed bugs are confirmed, the principal or site manager shall promptly notify:

(i) Head caretaker/family team leader

(ii) Manager, Occupational Health and Safety

(iii) Superintendent of education

(iv) Toronto Public Health

(v) Organizations leasing space in the school

Source: Toronto District School Board Operational Procedure PR599 (PDF)

Treatment would then trigger additional notifications to parents, staff and organizations that lease space on the site.

Additional documents:

Form 599A: Signs of Bed Bugs Reported (Notification Letter)

Form 599B: Students Sent Home from Outdoor Education Site (Notification Letter)

Form 599C: Signs of Bed Bugs; Continued/Resumed Use of Facility (Notification Letter)

Toronto Public Health Bed Bug Fact Sheet

The New York City schools bed bug kit (PDF) for comparison.

Thinking through procedures and notification policies as bed bugs prove themselves to be extremely challenging in schools is absolutely necessary. Schools are in a very difficult position because the root of the problem is elsewhere, in the homes of children and staff who are affected. However, schools are also uniquely positioned to disseminate good bed bug information and, well beyond that, to actually educate their communities, especially those who do not have access to professional pest control services, about mitigation strategies.

I wonder for how long actual eradication will continue to be beyond our reach.

Bed Bug Central’s charitable holiday treatments

by Renee Corea on December 4, 2009

in News

Bed Bug Central is coordinating charitable bed bug treatments for the holidays.

If you operate a facility in NYC or are dealing with an infestation at home, you can apply to receive a single treatment that is intended as a palliative:

These efforts are not intended to eliminate all bed bugs from your home or facility but to better the situation and provide you with some comfort as the holiday season approaches.

Details of the program and how to apply here:

In areas where participating companies are located (NJ and PA), pest control professionals will arrive at your home or facility on the 12th or 19th of December and render pest control services in an effort to better the situation and provide some relief from the stress created from dealing with a bed bug infestation.

I know that the holidays are an especially difficult time to cope with a bed bug infestation.

The companies that would provide the service are part of Bed Bug Central’s bedbugFREE network. (In the five boroughs, the company that would participate in this program is Parkway Exterminating.)

We have a no-advertising policy here and this is a form of marketing, but I think this will do someone somewhere a great service in a time of need. Well done, Jeff White, for thinking this one up. (You can see Jeff’s bed bug education videos here. I like the one about vacuuming. I think the message that vacuuming is effective but not a complete control method needs to get more play. Jeff would do well to get out from behind the desk more often, don’t you think?)
