A new study of field populations of several common bed bugs (Cimex lectularius) found that certain populations are less sensitive to two commonly used insecticides.
Pest control professionals are wise to fight the continued epidemic of bed bugs because they have adopted a comprehensive set of measures to reduce their dependence on chemical control, because new research shows that bed bugs are resistant to two commonly used insecticides. Early signs.
In a study published this week in the Journal of Economic Entomology, researchers at Purdue University found that out of 10 bed bug populations collected in the field, 3 populations were highly sensitive to chlorpheniramine. Decreased, and the sensitivity of five of the populations to bifenthrin also decreased.
The common bed bug (Cimex lectularius) has shown significant resistance to deltamethrin and other pyrethroid insecticides, which is believed to be the main reason for its resurgence as an urban pest. In fact, according to the 2015 “Insects Without Borders” survey conducted by the National Association for Pest Management and the University of Kentucky, 68% of pest management professionals believe that bed bugs are the most difficult pest to control. However, no studies have been conducted to investigate potential resistance to bifenthrin (also pyrethroids) or clofenazep (an pyrrole insecticide), which prompted Purdue University researchers to investigate.
“In the past, bed bugs have repeatedly demonstrated their ability to develop resistance to products that are overly dependent on their control. The findings of this study also show that bed bugs have similar trends in the development of resistance to clofenazep and bifenthrin.” Purdue Said Dr. Ameya D. Gondhalekar, research assistant professor at the University’s Urban and Industrial Pest Management Center. “Considering these findings, and from the perspective of pesticide resistance management, both bifenthrin and chlorpheniramine should be used in combination with other methods used to eliminate bed bugs to maintain their efficacy for a long time.”
They tested 10 bed bugs collected and contributed by pest management professionals and university researchers in Indiana, New Jersey, Ohio, Tennessee, Virginia and Washington DC, and measured the bed bugs that were killed within 7 days of exposure to bed bugs. percentage. Insecticides. Generally, based on statistical analysis performed, compared with susceptible laboratory populations, populations of bugs with a survival rate of more than 25% are considered to be less sensitive to pesticides.
Interestingly, the researchers found a correlation between clofenazide and bifenthrin susceptibility between bed bug populations, which was unexpected because the two insecticides act in different ways. Gondhalekar said that further research is needed to understand why less susceptible bed bugs can withstand exposure to these insecticides, especially clofenazide. In any case, compliance with integrated pest management practices will slow the further development of resistance.
“A large number of studies have shown that if insecticides are combined with other control measures such as vacuuming, steaming or heating, mattress covers, traps and desiccant dust, effective bed bug control can be achieved, and theoretically, This should reduce the growth of drug resistance in the at-risk population,” Gundalka said.

Thank you for your article, but this is old news for the pest control industry, and many products have continued to develop from these two products.
“Theoretically”………….. I really think that the theoretical application value is not high in the following situations: such or any pests are always resistant to pesticides and cause more Toxic applications. In theory, super heat treatment is the only real way to get rid of houses or apartment buildings, motels, hotels, etc. I have done extensive research on this, and toxic pesticides will never be a permanent solution. Why “manage” these horrible creatures, while using neurotoxins and other pathogenic chemicals that may be related to Parkinson’s disease, Alzheimer’s disease, epileptic seizures, asthma, cardiopulmonary hyperactivity, nausea, gastrointestinal discomfort Substances come to poison people’s homes. Heating is the only way to kill them and all their small eggs and larvae! ! !
The correct execution of heat is effective at all stages, but heat does not have any residual effects. The possibility of re-infection can return to its original state. Although its true resistance is an ongoing problem with pesticides and pests-this is not why we have imposed this plague on the United States again. This is the EPA and the “Food Quality Protection Act” to eliminate effective and cheap pesticides. Over the years, there has been no evidence of resistance to carbamates or organic phosphates. As for all the so-called diseases caused by pesticides, they are speculative. Before these statements, there are always cunning words and phrases, such as “suspicion, association, may cause, research shows, may cause, long-term effects are unknown, express concern, express some kind of concern, experts worry”.
The truth of the matter was in 1945, when the boy returned from World War II, and bed bugs were everywhere. But they were used in conjunction with DDT, and by 1946, the first society in human history eliminated them. The answer in 1946 was effective, cheap, easily available, and easy-to-use chemicals-pesticides-if it wasn’t the answer, then there will be no answer now.
And one more thing. If anyone wants a more comprehensive understanding of the bed bug plague in the United States, please refer to the “My Bed Bugs” series.
The best solution to the bug problem is hot fix! This is the most advanced technology to eliminate bed bugs in 1 day! This customized state-of-the-art manufacturing system includes RX12 heaters, air movers, wireless temperature controllers and monitors specifically designed to eliminate bed bugs. Once the system is installed, we will maintain a high temperature at 130 to 148°F (Fahrenheit) and kill bugs, nymphs and larvae within minutes. Bed bugs are ectoparasites with an external skeleton that quickly dry out and rupture at high temperatures.
Is there a chemical substance or an app that contains all three scientific formulas or solutions to stop bed bugs from not heating
