Bedbug populations pose persistent infestation risks amid insecticide resistance and health questions
Experts highlight prevention and professional treatments as bedbug populations persist, with lab studies probing potential transmission of antibiotic-resistant bacteria.
The short version
- Bedbug activity typically peaks during the summer, driven by increasing resistance to common chemical insecticides.
- While bedbugs historically have not been proven to transmit human diseases, a 2023 lab study showed they could acquire and transfer MRSA between artificial skin membranes.
- Entomologists advise rigorous prevention, such as inspecting hotel beds and secondhand items, as well as using professional heat or silica treatments to clear infestations.
Key facts
- Bedbug populations have rebounded and grown more prevalent over recent decades due to increasing resistance to chemical insecticides.[Associated Press]
- A 2023 University of South Dakota laboratory study demonstrated that bedbugs could acquire MRSA during a feeding and transmit it during a subsequent feeding across artificial skin capsules.[Associated Press]
- Commercial rankings of cities with the worst infestations, such as those compiled by Orkin and Terminix, rely on internal service call volumes rather than comprehensive public surveys.[Associated Press]
- Effective non-chemical eradication methods include silica dust and sustained professional heat treatments reaching at least 122 degrees Fahrenheit.[Associated Press]
What remains uncertain
- Researchers have not confirmed through follow-up studies whether bedbugs can actually transmit MRSA to humans outside laboratory conditions.[Associated Press]
- The true national prevalence and geographic distribution of bedbug infestations remain unmeasured by standardized public health data.[Associated Press]
