PCT Magazine recently published a bed bug supplement stating that more than 550 professionals seeking bed bug knowledge turned out in September for Bed Bug University’s North American Summit in Chicago. The event, produced by BedBug Central, featured leading university researchers and drew executives from pest management, hospitality, university, housing authority, and property management fields.
The major take-away: Bed bug knowledge continues to grow, which means evolving strategies for the pest’s prevention and control. Here are some topics covered in this very informative bed bug writeup:
- Bed bug anxiety
- Federal involvement
- Bed bugs without beds
- Help your client be the hero
- Early detection hits, misses
- Cheap and easy monitoring
- Consider the time factor
- Sofas, freezing, and follow up
- Bed bugs on treated surfaces

Does Lysol Kill Bed Bugs?
Similarly to common insecticide spray, Lysol itself will kill the bed bugs only if you sprayed directly on the bugs with it. Areas sprayed and treated with this disinfectant will only keep bed bugs away while it is still wet otherwise once it dries, the bed bugs will return again.
Does Alcohol Kill Bed Bugs?
Alcohol will kill bed bugs on contact and can be apply similarly like a bed bug spray. While it can be use temporaily as a bed bug repellent, it need to be used often to control an infestation since it does not remain long enough on the surfaces to continue killing the bugs. As such, it is not a very effective way to get rid of bed bugs permanently.
Does Bleach Kill Bed Bugs?
While bleach does kill bed bugs, the method is not recommended. Bleach will ruin carpet, furniture, mattresses and paint as well as also cause irritation to your skin. It is best to limit its use for killing bed bugs in items you can launder and hard surfaces that are bleach safe.
Does Boric Acid Kill Bed Bugs?
Boric acid is often used as an insecticide and repellent for the control of cockroaches, termites, fleas, silverfish, and many other insects. However boric acid is a stomach posion and the commerical attractants maunfactured in it to attract common insects will not work on bed bugs since bed bugs are attracted by carbon dioxide and will only feed on blood. Furthermore, boric acid is especially toxic to small children and animals and can cause serious kidney damage when accidentally consumed.
Bottom line, bed bugs are resourceful, opportunistic and are a very hardy pest and currently, there are no known medically proven bedbug-proof repellent that will work 100 percent to repel them or their bites. Creams or lotions for the skin will not stop their growing populations which can escalate into a full blown bed bug infestation within the house or apartment.

Even A Few Surviving Bugs Can Reproduce Quickly.
Researchers said bedbugs are able to inbreed with close relatives and still produce healthy offspring. That means that if just a few bedbugs survive in a building after treatment, they repopulate quickly. The new research helps to explain why bed bugs are so hard to eliminate.
The new research was presented Tuesday in Philadelphia at the annual meeting of the American Society of Tropical Medicine and Hygiene. Bedbugs are wingless, reddish-brown insects that bite people and animals to draw blood for their meals. Their bites can cause itching and welts, although some people have no reaction to bed bug bites. Researchers also said they found many different strains of bedbugs throughout the East Coast, meaning they’re coming into the country from lots of different places.

A North Carolina State Univ. discovery of the unique chemical composition of a cockroach signal – a “Let’s hook up” sex pheromone emitted by certain female wood cockroaches to entice potential mates – could have far-ranging benefits, including improved conservation of an endangered woodpecker.
Coby Schal, Professor of Entomology at NC State and the corresponding author of a paper describing the discovery, says that the study, published the week in Proceedings of the National Academy of Sciences, advances the knowledge of fundamental biological and chemical properties of an important North American cockroach genus that serves as both a beneficial forest insect and as a pest in homes.
Parcoblatta lata is the largest and most abundant of the wood cockroaches. It also serves as the favored meal of the endangered red-cockaded woodpecker. Schal says that the study, which characterized the pheromone and produced a synthetic version of it, could help scientists determine whether certain habitats have enough woodpecker food. If the synthetic pheromone attracts large numbers of adult male P. lata cockroaches, Schal says, then the roach supply is probably ample. Provided that other aspects of the habitat are also right, the area could be a suitable home for red-cockaded woodpeckers.
Besides feeding woodpeckers, Parcoblatta adult males are excellent flyers that occasionally infest houses after being attracted to porch lights. The pheromone could help control wood roaches near homes, Schal says.
Schal and colleagues from New York and California combined a number of study methods to understand P. lata’s aphrodisiac. The team used gas chromatography, in which compounds are separated in a controllable oven, to separate it from other chemical compounds that the roaches produce. By connecting this instrument to the antenna of P. lata and monitoring its electrical activity, the researchers zeroed in on the biologically active compound. They then used nuclear magnetic resonance to determine the pheromone’s chemical structure. Finally, they made a synthetic version of the compound to see if it would attract adult male P. lata.
It did. Perhaps surprisingly, it attracted a few other Parcoblatta species, as well. One common wood roach, however, was conspicuously absent: Parcoblatta pennsylvanica, which ignored the synthetic pheromone. As its name implies, P. pennsylvanica has populations into the Midwest and mid-Atlantic states.
“Parcoblatta cockroaches are endemic to North America; unlike pest cockroaches, they were not introduced from other places,” Schal says. “The compound we identified is a major component of a multi-component sex pheromone blend. So learning that the chemical we identify in this paper attracts some Parcoblatta species but not others tells us something about their evolutionary history.”
The roaches that respond to this pheromone probably make up a group of closely related species, Schal says, which together diverged from other Parcoblatta species that either can’t smell this chemical or are attracted to it only when it’s combined with other, yet to be identified, pheromone components.

- Do not Panic. Bed bugs can be removed with careful inspection and by using proper control methods.
- Do not try to kill bed bugs by using agricultural or garden pesticides. Using outdoor pesticides to control bed bugs can make you or your family very sick.
- Do not use products that appear to be “homemade” or “custom formulated.” Homemade products could be dangerous and they might make the problem worse.
- Do not use products that have labels in a non-English language.
- Do not apply pesticides directly to your body. This could make you very sick.
- Do not use rubbing alcohol, kerosene or gasoline. These chemicals may cause fires.
- Do not throw away your furniture. Beds and other furniture can often be treated for bed bugs. Throwing away your furniture can spread the bugs plus you will have to buy new furniture.
- Do not store things under the bed. Storing stuff under the bed gives bed bugs many new places to hide. This makes it more difficult to get rid of bed bugs.
- Do not move things from room to room. Moving your things from the room with bed bugs to another room in your house may spread the bed bugs.
- Call a professional pest management company that specializes in bed bug removal.

There are many methods being used for bed bug extermination and bed bug pest control in New York, New Jersey and Connecticut. How do you know which option is right for you? Want to find out which option is best for your situation? Contact J.P. McHale Pest Management.
Heat Treatment: One example is ThermaPure. This method uses heat to kill the bed bugs. The Thermal death point of Bed bugs and Bed Bug Eggs is about 114 degrees. This method raises the internal temperature of your structure to a temperature of 130 to 150 degrees, and is held there for around two to four hours. This ensures that the temperature in the walls and in any furniture reaches the minimum of 120 degrees, thus killing bed bugs and eggs.
Pros: No insecticides are used, If performed correctly only one treatment needed, most belongings can remain in your house and will be treated.
Cons: Difficult method to use for multi-unit dwellings, Precautions must be taken for heat sensitive belongings, No residual killing if any bed bugs survive re-infestation can occur, cost.
Cyronite: This method of treatment utilizes subzero CO2 ”snow” to kill bed bugs on contact.
Pros: No insecticides are used, Dry CO2 can be used in and around electrical sockets,Kills instantly
Cons: It is a contact kill only – no residuals effects, any bed bug harborage that is not hit directly can survive.

Vikane Gas: This method uses fumigants to kill bed bugs. Normally only used in major infestations
Pros: Fumigants reach deep into cracks and crevices, killing bed bugs, if performed correctly this can be a fast method for killing bed bugs
Cons: This method is not legal in all states, Cost, hard to treat multi-unit dwellings, everyone including pets must evacuate the structure.
Conventional Pesticides: This method uses pesticide sprays and dusts
Pros: Normally the least expensive option, can be used in all building types, uses pesticides with a residual killing effect typically between 14 to 30 days.
Cons: This method needs multiple treatments – typically 2 to 3 visits. The sprays and dusts do not kill bed bug eggs.
Note: A proper and diligent inspection of the property to verify bed bug activity and locate the bed bug harborage is the most important aspect of bed bug control. The use of steam (to kill eggs) and diligent vacuuming is also very important. In muti-unit dwellings sealing cracks and crevices (paying attention to electrical outlets) will help to stop the spread of bed bugs from unit to unit.

Do you know what bed bug detection method is the most accurate?
There are many companies creating new devices as the bed bug epidemic in the United States increases. Unfortunately, many of these technologies are not fully evaluated before they are released and used by the public and pest control industry.
Jeffrey White, an entomologist at Bed Bug Central, wrote a paper on the effectiveness and sensitivity of real-time PCR to detect bed bug DNA from swabs collected in both laboratory and field settings to evaluate the claims of Bed Bug DNA testing.
Here are some of the key findings from the Bed Bug DNA Test Results:
- It was found that bed bug DNA can be detected by real-time PCR if the swab is applied in an area where a bed bug has been and left DNA behind.
- Using PCR to assist in the detection of bed bug DNA is a technology that can be used to help identify the past or present presence of bed bugs.
- A “negative” test result should not be interpreted as meaning that bed bugs are not present since bed bug DNA may not have been left behind by a passing bug or the DNA may have been missed by the individual swabbing the area.
- A “positive” test results should be interpreted as meaning bed bugs are or were present within the last year.
- Bed bug DNA takes a year or more to denature and therefore it is not recommended that this test be used to determine if bed bugs have been eliminated or have been reintroduced if a bed bug infestation was present in the past.
- Due to the highly sensitive nature of this test, for those using this test that may be exposed to bed bug in other locations to where the test is being applied, cross-contamination is a serious concern and should be addressed accordingly.
- Real-time PCR cannot currently differentiate between the Common Bed Bug, C. lectularius, and Tropical Bed Bug, C. hemipterus.
- Bed bug DNA takes an unknown length of time to breakdown and “positive” test results were observed in areas where bed bugs had been dead for over one year.
- In low and moderate level infestations where monitoring technology is truly needed since bed bugs can be difficult to find through visual inspections, real-time PCR can detect bed bug DNA IF the swab was used in an area where bed bugs left DNA behind. Meaning that the test is inconsistent in low and moderate level infestations because it is impossible to determine where bed bug DNA will be.
- Real-time PCR is an extremely sensitive technology and areas being swabbed can be contaminated with bed bug DNA even though bed bugs may not be present.
- Anyone using this test should not determine that a “negative” test results means that you do not have bed bugs.
- The results of this study clearly demonstrated that bed bug DNA can be detected up to a year or more after it was shed by a bed bug.
- This test may not be ideal for someone who has had bed bugs in the past because the result of the test will most likely be returned “positive”.
- Bed Bug DNA testing may provide the client potentially false information that they again have an active infestation.
- If a swab is returned “positive” for bed bugs, a visual inspection should be conducted to confirm the presence of bed bugs to rule out a false-positive on old evidence or contamination transferred in from an infested environment.
Jeffrey White concludes, “As more and more bed bug detection devices and technologies become available to the public and pest control industry, it is important to properly test these devices prior to drawing conclusions on any results they may provide. Using real-time PCR analysis to detect bed bug DNA has the ability to help a homeowner or pest control company identify if bed bugs are present but should not be relied upon to indicate if a home or location is free of bed bugs. Also, using this test determine if bed bugs are still present after an infestation is treated is also not recommended due to the slow way in which DNA denatures. This tool should be viewed as another method to confirm the presence of bed bugs when a homeowner suspects them but has been unable to visually confirm bed bugs.”

Here’s a new bed bug novel that is sure to make your skin crawl. Here’s a sneak peak at what you’re in for:
“Big mistake: Susan soon discovers that the brownstone is crawling with bedbugs . . . Or is it? She awakens every morning with fresh bites, but neither Alex nor their daughter Emma has a single welt. Exterminators search the property and turn up nothing. Neighbors insist the building is clean. Susan fears that she’s going mad-but as the mysteries deepen, a more sinister explanation presents itself: She may literally be confronting the bedbug problem from hell.”
