All naturally occurring, human-associated bedbug populations have high levels of resistance to Pyrethroid and Carbamate insecticides.
Insecticide resistance typically declines with time in culture. Cimex Store regularly establish new cultures in order to be able to provide cultures with realistic resistance levels.
If you require bedbugs with typical levels of insecticide resistance, please contact us before placing your order to discuss the availability of the stocks we currently hold.
Cimex Store also keep a “Resistance maintained” bedbug culture, which is challenged annually to maintain typical levels of resistance to Pyrethroids.
