They also have novel modes of action, making them useful when combatting resistant pest populations. Provide an effective and economical treatment option with two applications per year (fewer re-treats, etc.). There is only one insect growth regulator that is labeled for bed bug control; hydroprene, which is available as a liquid or an aerosol. The business of bed bugs. Hatching rates for eggs ranged from 95 to 100 percent and were statistically no different from spraying only water. The white-footed mouse, Peromyscus leucopus, is closely related to the deer mouse with similar appearance and habits. We suggest that methoprene could be incorporated into integrated pest management programs in liquid baits and residual sprays in combination with other active ingredients. Similarly, no adverse effects were noted when third-instar nymphs were sprayed directly with an elevated (3x) concentration of Gentrol. Unlike other wingless insects such as fleas, bed bugs also are not equipped to jump long distances. Each of the five treatments was applied to groups of eggs laid within the previous 24 hours (one-day old eggs) or 48 to 72 hours (two- to three-day old eggs). Bed bug interceptors were installed throughout to monitor activity. In the last two decades, bed bugs (Cimex lectularius L. and Cimex hemipterus F.) have become perennial and difficult to control indoor pests. However, these effects occurred only from prolonged exposure to higher than labeled concentrations. How to get rid of bed bugs yourself Inspect - check bed bug hot spots such as mattress seams, bed frames, headboards, along the edge of carpets, and nearby furniture (cabinets, drawers, armchairs, sofas) for live insects. Ingestion of ≥10 µg/ml blood of either JHA by last instar nymphs reduced oviposition; untreated females that mated with males exposed to high concentrations of either JHA also exhibited lower oviposition. The device is small, and can be installed on walls or behind furniture. Search for other works by this author on: © The Author(s) 2020. In these sites, technicians should take special precautions, including the use of a respirator with a high-efficiency (HE) filter. Figure 1: Efficacy of Phantom SC termiticide-insecticide residual deposit on two surfaces on two pyrethroid-resistant bed bug strains during University of Kentucky study by Drs. Contact him at. “Bed bugs continue to increase their presence across the U.S.,” said Stoy Hedges, entomologist with Terminix. Potter, M.F., K.F. Since the compounds are not intended to kill quickly, they’re usually applied in combination with other faster-acting materials. Hydroprene, which has a low level of toxicity to humans and pets, is another chemical that is effective as a bed bug insecticide. A spot treatment was performed, and the bedroom was vacuumed. Suppliers: If you have a bed bug control control product you’d like see featured in an upcoming issue of PCT, please send a press release and high-resolution photo to jdorsch@giemedia.com. Insecticide applications are classified under different groups such as Diatomaceous Earth, Crease and Crevice, Deltamethrin, Hydroprene, Indoor Surface, Fumigation, and Indoor Space.

However, bed bugs are skilled climbers. Terminix Ranks Most Bed Bug-Infested Cities. “The flyer can be customized with a company’s logo, phone number and website and is available in a variety of quantities to meet the needs of even the smallest pest control company.”, Additional information and an order form can be found at www.HowToMarketPestControl.com, Speakers for North American Bed Bug Summit Announced. Several days after the initial treatment, the customer called and said the pesky bed bugs were still in the boy’s bedroom. It should be noted that Precor IGR Concentrate is not currently registered for bed bugs although industry surveys indicate use by some companies. “Nothing has changed. All experiments were replicated (repeated) four times. Ovicidal effects of two juvenile hormone analogs, methoprene and hydroprene, on the human body louse and the bed bug. Results. 77(7): 37, 39-41, 43. One option is products that contain the active ingredient chlorfenapyr, which disables an insect’s ability to produce energy. We used industrial vacuum cleaners to remove bed bugs and eggs; commercial steam cleaning was used on the mattress, box spring and metal bed frame to kill the bugs and their eggs. Different types of IGRs have different modes of action. When the nest becomes too foul after a few weeks, the female moves on and builds a new nest nearby. At 2× the label rate, confinement to residues of Gentrol(®) [active ingredient (S)-hydroprene] had no significant effect, but residues at 3× and 10× the label rate caused a reduction in fecundity and impaired development. This article presents our findings on the impact of IGRs on bed bugs. Structural deformities were common in bugs reared on high (10x label) concentrations of Gentrol. Bugs without borders: defining the global bed bug resurgence. Subsequent dissections revealed that many non-laying females exposed to elevated concentrations of Gentrol had in fact formed eggs — but the eggs were retained in the abdomen. One late summer day in 2010, our firm received a call from a client who told us her son wakes up every morning with multiple “mosquito bites.” We knew what that sounded like. Don't already have an Oxford Academic account? “Now that the industry has begun working together it’s easier to see the best way forward.”, While anyone can be affected by bed bugs regardless of income level or where they live, the ability to deal with the situation can vary. 2008. Bull Fac Earth Sci (King Abdulaziz Univ.) Department of Entomology and Plant Pathology, North Carolina State University. Then a direct-contact insecticide treatment is applied, followed by spot treatments of a residual insecticide. They’re often found nesting in unused stuffed furniture, or in cabinets, boxes or equipment. Groups of previously fed, unmated adult bed bugs (5 males, 10 females; NY-1 strain) were held continuously on the treated surfaces and mortality, oviposition and egg hatch were recorded daily for 20 days. During experiments bed bugs were maintained on an artificial feeding system. A post-treatment inspection was scheduled for 10 days later. Cirkil RTU is a ready-to-use formulation containing 5.5 percent cold-pressed neem oil. It is spread to humans mostly when airborne virus particles are inhaled. Phantom SC or PI can be applied as a Crack & Crevice treatment to common bed bug harborages. Pyrethrins are derived from chrysanthemum flowers and are botanical insecticides, whe… The conference is a BedBug Central learning event that provides education and information on all things bed bugs, including sessions and presentations led by industry experts. The retained eggs did not hatch, but the embryos inside were partly developed. Evaluation Methods. Based on these studies, hydroprene and methoprene seemingly should have minimal effect on bed bug reproduction and development when used at label concentrations. Bugs were on the ceiling tiles. Methoprene Insect Growth Regulator (IGR) Methoprene is an IGR that does not directly kill adult insects but works on certain pests in their immature (egg, larvae) stages, thus breaking the cycle of infestations and preventing re-infestations. 2006. Takahashi, M., and T. Ohtaki. Mark H. Goodman, Michael F. Potter and Kenneth F. Haynes, YouTube: Why Mosquitoes Bite Some People More Than Others. Mouse Behavior. Additionally, University of Minnesota research showed a near exponential increase of chlorfenapyr uptake by bed bugs the longer the interval between application and exposure (see Figure 2 below) for Prescription Treatment brand Phantom Pressurized Insecticide. The union representing the city’s bus drivers has asked City Council to put pressure on the Detroit Department of Transportation (DDOT) to help curb the problem and stop the spread of the beg bugs. hydroprene are relatively harmless to non-arthropods and have proved to be effective against other urban insect pests. In experiments 1 and 2, adult (NY-1 strain) bed bugs confined since they were third-instar nymphs on 3x label concentrations of Gentrol laid 77 percent and 49 percent fewer eggs, respectively, than bugs exposed to water alone. Upon hatching, 20 newly-emerged (first-instar) nymphs from each treatment were fed and returned to their respective containers (additional nymphs were discarded). Current pest control options are severely constrained by high prevalence of insecticide resistance and availability and relatively high costs of alternative interventions. May you get bed bugs, Scrapers. Bed bugs do not have wings and are not capable of flight. Although hydroprene did not appear to interfere with nymphal development, fifty percent of the bed bugs died during the final molt. Despite the fact that it does not kill bedbug directly, it is very useful in preventing bed bug reproduction, so it’s probably the best way to kill bed bugs. 2008, Shaarawi et al. 1989), oriental cockroach (Bao and Robinson 1990, Short and Edwards 1992, Edwards and Short 1993), and mole crickets (Parkman and Frank 1998), hydroprene has been shown to be more effective than … JHAs, such as hydroprene and methoprene, have a desirable safety profile and are effective against a variety of indoor pests. And because they are nonrepellents, they won’t cause bugs to disperse. “Even before an infestation occurs, people can protect themselves by using entry, escape and bite-proof mattress and box spring encasements,” Bell said. The home range of a deer mouse nesting outdoors can be up to an acre or more. Terminix released its first bed bug ranking in 2010. Nymphs Continuously Exposed to Dry Residues. The retained eggs did not hatch, but showed partial development of the embryo, with eyes, legs and segmentation visible. : 4-15. If you decide to control bed bugs on your own, there are a few steps you can take straight away to try and manage a small bed bug problem. 1981. Remove soiled clothes and vacuum away insect eggs and droppings. “We’ve created this full-color, high quality flyer to give pest control companies another communication tool they can use to educate their customers,” said June Van Klaveren, owner of Compelling Communications. Snap traps baited with standard mouse baits will capture deer mice and deer mice also will feed on standard rodenticide baits. The virus is found in the saliva, urine and feces of these mice. Oxford University Press is a department of the University of Oxford. Published by Oxford University Press on behalf of Entomological Society of America. Bed bugs are are small insects that often dwell in the nooks and crannies, evading capture. It has a flexible, whole-room application, and is labeled for use in hand-pump sprayers. Some studies show that they climb great heights in order to drop themselves down to lower surfaces that were otherwise inaccessible to them. A technician was sent back, where he found more live and dead bugs in the same locations. Be forewarned that the experiments were fairly complex — but necessary to measure effects on reproduction and development as relates to management. However, research has revealed that IGR products aren’t working as promised. In short, we were thorough. The most common insecticide used is deltamethrin. The Gentrol ® insect growth regulator, (S)-hydroprene, effectively breaks the insects’ life cycles and offers 120 days of control. Shaarawi, FAI, WAM Radwan and SA Soliman. If PMPs end up with three or more retreats when using pyrethroids as the primary treatment material, they should evaluate their application technique. Tiny red eyespots can be seen on the two embryos to right of center, while the dark structure toward the bottom is the gut. About 50 Detroit bus drivers have reported bed bugs on city buses within the past year, The Detroit News reported. A liquid kairomone lure that works to attract bed bugs seeking a meal. Other strains have more effective enzymes that break down the chemical once inside the insect’s body. References using a mild steroid cream like hydrocortisone cream to ease bedbug bites (children under 10 and pregnant women should get advice from a doctor before using hydrocortisone cream) antihistamines – these may help if the bites are very itchy and you're unable to sleep. There also were no significant differences in subsequent numbers of eggs laid per female after a blood meal (7.1 with water vs. 6.5 with Gentrol), nor hatching (97 vs. 94 percent). A liquid pheromone lure that encourages bed bugs to aggregate in the device. They can hide in many places such bed frames, mattresses, clothing, furniture, behind pictures and … Cirkil products kill bed bugs and prevent bed bug eggs from hatching. A field study conducted using beta-cyfluthrin (Tempo® SC Ultra), deltamethrin (Suspend® SC), and hydroprene (Gentrol®), the traditional bed bug treatment, in low income housing apartments significantly reduced the bed bug infestation ; however in laboratory studies, pyrethroid products were not significantly effective against a field strain bed bugs , and they did not kill 100% of a susceptible … Effects on female fecundity. To register for the Summit visit http://bit.ly/MwjpVC. Am Entomol 52: 113–116. Outdoor nests are made of stems, twigs, leaves and roots, and may be lined with feathers or fur. Two supervisors were sent to investigate this somewhat peculiar situation — they found living and dead bed bugs on the windowsill. Applications of Gentrol repeatedly had no acute (immediate) effect on eggs, nymphs or adults, even when the respective life stages were sprayed directly. Living with bed bugs. The product’s active ingredient, Residulen, is derived from soy bean oil and dissolves the cuticle of the insect. In infested dwellings, many more variables can impact performance, including non-continuous coverage, insect mobility and intermittent exposure to insecticide deposits. Prevention is a new reality. Speakers for the 2012 North American Bed Bug Summit, set for Sept. 6-7 in Las Vegas, have been announced. Between carpet or floor coverings and walls also are good spots for treatment.

The deer mouse, and sometimes the white-footed mouse, are the mice primarily responsible for transmitting Hantavirus to humans. Juvenile hormone analogs (JHAs), such as hydroprene and methoprene, disrupt these processes by imitating abnormally high levels of JH in exposed individuals. Alpine Dust Insecticide and Alpine Pressurized Insecticide have both demonstrated excellent residual activity on a variety of surfaces for bed bug control. While the house mouse occupies urban areas, the deer mouse is more common in rural or semi-rural areas. Masonite disks were treated with 3x the label concentration of Gentrol or water alone, allowed to air-dry for 24 hours, and placed in individual containers. Pest Management Professional. Cirkil RTU will be available for professionals to sell to customers. Both will feed on humans, though they require different abatement techniques. Entomologists Say 2012 is Pivotal Year in Bed Bug War. No adverse effects were observed when bed bug eggs were sprayed directly with Precor or Gentrol, regardless of concentration applied or whether eggs were treated at one or three days of development. Effect on egg viability and embryogenesis. In some cases, bed bugs’ exoskeletons can reduce the penetration of the insecticide. Gentrol ® IGR Concentrate provides professionals the flexibility required for uniform applications across multiple sites for the control of … PestWorld.

Upon reaching adulthood, each individual was paired with an untreated adult bed bug of the opposite gender to monitor any subsequent effects on oviposition, hatching and mortality. You could not be signed in. But, according to research published by the University of Kentucky, bed bugs tend to avoid areas where pyrethroid insecticides have been used. Inside, they nest in many of the same locations as house mice. In most cases, a mixture of insecticides is applied to bed bug infestation to get rid of the problem. Bugs and eggs from the respective strains were exposed to the IGRs as a direct spray, and by confinement on previously treated surfaces. In a second series of experiments, Masonite wood disks were treated with 1x or 2x label concentrations of Precor, 2x or 3x concentrations of Gentrol, or water alone, and allowed to air-dry for 24 hours. The physiological basis for the greater inhibitory effect on the two field strains versus the laboratory (FD) strain is unclear. If not, you better find out. We evaluated the potential of hydroprene and methoprene to be incorporated into an ingestible bait, with dose–response studies on fifth-instar male and female bed bugs. Nothing has improved,” the customer told us days later. What was thought to be a particularly troublesome bed bug infestation was something else — and turned out to be a lesson in the importance of accurate pest identification. Using chlorfenapyr- or dinotefuran-based products as foundational non-repellents — pest management professionals should treat primary areas every six months, while secondary areas should be treated once every 12 months. For full access to this pdf, sign in to an existing account, or purchase an annual subscription.

RESULTS: At 1× and 2× the label rate, Precor ® [active ingredient (S)‐methoprene] had no significant effect on the development or fecundity of bed bugs. (See photo above) Other abnormalities were also noted at elevated Gentrol levels, especially the 10x concentration. Let’s start with pyrethrins. Cirkil CX1 is an emulsifiable concentrate containing 22 percent cold-pressed neem oil. Groups of 30 fed and mated adult females from three different colonies (FD, NY-1 and CIN-1) were placed on each treatment and allowed to lay eggs for 24 hours, after which the adults were removed. The author is an urban entomologist with Arrow Exterminating Company in Lynbrook, N.Y. One thing that makes the Eco Raider a top choice for households is its … Bed bugs utilized in each of these studies were from long-maintained laboratory colonies (more than 23 and more than 32 years, respectively), whose vulnerability to insecticides may have influenced the outcome. “People with means tend to get bed bugs once, pay the costs to eliminate them quickly and learn ways to avoid them,” said Jody Gangloff-Kauffman, senior extension associate with the New York State Integrated Pest Management Program at Cornell University. Cimi-Shield is available in two formulations: Knock-Out, for active infestation, and Protect, for sites where there is constant pressure such as healthcare facilities, hotels or dressing rooms. As the bug’s body breaks down the insecticide chemical, the pest grows tired and dies. The heaters have shown a high return on investment by substantially decreasing treatment times and the ability to treat a larger area per heater, the company said. When evaluating delayed-action insecticides, repetitive blood meals are needed since the nymphs must feed between molts. Gentrol (Central Life Sciences) with (S)-hydroprene as the active ingredient, is often employed in bed bug management programs. While the bat bugs were feasting on their prey of choice outside the window, they were more than happy for a different meal inside the bedroom. This article is published and distributed under the terms of the Oxford University Press, Standard Journals Publication Model (. The solution kills bed bugs in hard-to-reach places, such as cracks and crevices. This article is also available for rental through DeepDyve. Methoprene (the active ingredient in Precor) had no effect on bed bugs at 1x and 2x the label concentration for fleas. I confirmed they were, as he had suspected, bat bugs. Insect growth regulators, such as hydroprene (Gentrol), are also sometimes used. Bats were roosting behind the shutters, and the siding behind the shutter was encrusted with bat droppings and bat bugs live and dead. Organic and conventional pesticides were used. Each bug was also examined for deformities and females were dissected to count any eggs remaining in the abdomen. Instead, the white-footed mouse occupies much of this region. The 2011 bed bugs without borders survey. Nonetheless, published research on the effects of IGRs on bed bugs is sparse. Incorporating the BASF Proactive Bed Bug Treatment Protocol of using non-pyrethroid chemistry like chlorfenapyr and dinotefuran can: Long-lasting residues from the foundational non-repellents in the SmartSolution for bed bugs from BASF Pest Control Solutions effectively kills pyrethroid-resistant and nonresistant bed bugs. We suggested the luggage might have been the source of the infestation, and we recommended a bed bug intervention service. OOK-Press Kft, Veszprem, Hungary. ), Proceedings, Sixth International Conference on Urban Pests, 13-16 July 2008, Budapest, Hungary. It is commonly used for roach, fly,bedbug,and stored product pest control. One type of chemical used to kill bedbugs is the insect growth regulator or IGR called hydroprene. Research conducted at Virginia Tech showed that bed bug eggs sprayed directly with Phantom Pressurized Insecticide didn’t hatch (100 percent mortality). The supervisor collected samples and brought them to me. (Recall that bed bugs normally molt five times en route to becoming adults, progressing through five nymphal stages or “instars.”) Adult females must also blood feed in order to lay eggs. Effects of juvenoids on some biological aspects of the bed bug, Cimex lectularius L. II. The deer mouse also commonly nests in abandoned vehicles or farm equipment where it chews into upholstered seats and gnaws on electrical wires. Physical Characteristics. Naylor R, D. Bajomi and C. Boase. IGRs the industry uses to fight fleas, cockroaches, mosquitoes (and bed bugs) on the other hand mimic insect juvenile hormone (JH). Other cities, such as Columbus, Dallas, Philadelphia, San Francisco and Washington, D.C., saw growing bed bug populations this year. Shaarawi, FAI, WAM Radwan and SA Soliman.

BedBug Chasers Franchises Bed Bug Killing Business. This makes it harder to segregate results attributable to the IGR alone. Reduce customer complaints, litigation and “down time” for hotel rooms. Elevated (3x and 10x) label concentrations of Gentrol did reduce the number of eggs laid by two different bed bug field strains. They carry this food to their hiding places in cheek pouches. Since Hydroprene controls bed bug reproductive rates, this chemical would allow pest management professionals greater control of bed bugs in infested locations and giving them a resistance management tool. Indoors, inspect potential nesting areas mentioned above. “While major metropolitan areas are most at risk, it is important to note that bed bugs have been spotted in cities and towns across the country.”. The wetted third-instar nymphs were then transferred to new containers, fed weekly and observed for adverse effects. Efficacy of (S)-methoprene against Cimex lectularius (Hemiptera: Cimicidae), pp. Its long residual activity allows it to control recurring infestations, making it highly effective as a preventive treatment. Resistant bed bugs survive and move away from pyrethroid treated surfaces, which may eventually cause the infestation to spread to untreated harborages. Immediately after spraying, the eggs were transferred to a clean container and monitored daily for effects on hatching. We gave her information outlining the service our technicians would provide. Potter, M.F. Pyrethroids have long been the go-to chemistry for quickly knocking down bed bug populations. Direct Spray of Eggs and Nymphs. Terramera has announced two new neem-based biopesticides for the control of bed bugs, bed bug eggs and cellar spiders to be marketed under the Cirkil brand name. Sites favored for deer mice are drawers and storage cabinets in garages and sheds, attics if there are trees touching the roof, boxes and furniture stored in attics, and corner sill plates in basements and crawlspaces. More importantly, it is approved by EPA for use on the entire mattress. Egg retention within IGR-treated females was unusual, and to our knowledge, has never been reported. Juvenile hormone analogs (JHAs), such as hydroprene and methoprene, disrupt these processes by imitating abnormally high levels of JH in exposed individuals. This habit can result in infested areas with large numbers of odorous, abandoned nests which also increases the risk of Hantavirus exposure. Populations in Arkansas have been found to be highly resistant to DDT, with an LD 50 of more than 100,000 ppm. Cimi-Shield is non-toxic, FIFRA 25 (b) exempt. Other non-repellent solutions to consider are Prescription Treatment brand Alpine Dust Insecticide and Prescription Treatment brand Alpine Pressurized Insecticide, which contain dinotefuran. For more information about BedBug Chasers visit the company’s website at www.BedBugChasers.com. That “chirping” would be from hatchling birds…but that would only last until the chicks matured. Here’s what we found when we systematically put them to the test... Editor’s note: Portions of this article were adapted from a technical paper titled, “Effects of Juvenile Hormone Analog Formulations on Development and Reproduction in the Bed Bug,” in the entomology research journal Pest Management Science. Apply generally behind headboards and to box springs, bed frames and baseboards. Evaluating IGRs in bed bug-infested dwellings is problematic. Hydroprene This is a safe insecticide meaning it can be used almost everywhere. Both deer mice and white-footed mice urinate and defecate directly into their nests. The photo at left points out deer mouse features that are different from those of the house mouse. Pest Barrier has introduced Cimi-Shield, a product that kills bed bugs on contact, the company announced. This makes it a great product line for bed bug prone areas, even in sensitive accounts. IGRs are marketed with the promise of sterilizing bed bugs. Until recently, insecticide treatments for bed bugs have mostly been curative (i.e., to control an existing infestation). For more information, visit www.PestBarrier.com. Do you know the difference? In the boy’s room, the inspector found several dead bed bugs under the bed, and more on the window sill near the foot of the bed. The 2012 ranking proves bed bugs continue to be a problem across the country, with five cities — Cleveland, Houston, Indianapolis, Miami and New Haven — joining the top 15 this year. Verifi provides up to three months of active detection before re-activation is required with replaceable components, allowing for long-term monitoring. The elevated (3x label) concentration of Gentrol compared to water alone was also sprayed directly onto groups of 20 third-instar NY-1 strain nymphs.
