![]() With this in mind, the researchers created three experimental conditions to test how effective the permethrinimpregnated mattress liner proved against bed bugs. ![]() In their natural environment, bed bugs move around frequently when looking for a host or harbourage. hemipterus species originating from Australia, Malaysia, Sweden, the UK, and the US, with 21 collected during the modern resurgence of pyrethroid resistance. ![]() The purpose of the study was to determine if pyrethroid-impregnated mattress liners should, or should not be, recommended as part of an overall bed bug management program. In an effort spanning several years, the team of international researchers including Dr Chow-Yang Lee from the University of California and David Lilly and Stephen Doggett from the University of Sydney, Westmead Hospital, tested the ActiveGuard mattress liner against 24 strains of bed bugs. But the question is: does it really work?Ī study published in Journal of Economic Entomology in May 2022 tested the efficacy of the permethrin-impregnated mattress liner against the tropical and common bed bug in laboratories around the globe, in one coordinated study. Today it is being marketed for bed bug control. One example is the ActiveGuard mattress liner, a US product that contains 1.64% permethrin and was developed to protected against dust mites. In the US, consumers can purchase mattress protectors and liners that are made from fabric impregnated with a pyrethroid. The pest control market has responded by developing products that attempt to tackle the problem by creating a physical as well as a chemical barrier. In fact, in studies assessing resistance, all the field collected strains of the common and tropical bed bug have been found to be resistant to pyrethroids, with resistance further being reported to other types of insecticides, including neonicotinoids, organochlorides and organophosphates. Their presence is widespread and they are difficult to treat as levels of insecticide resistance are growing. The tropical bed bug, Cimex hemipterus and common bed bug, Cimex lectularius present a global problem.
