Cockroaches are insects found in almost all habitats, including unsanitary environments. Understanding their microbial communities is crucial for assessing the potential risks they pose as vectors of pathogens. In this study, we assessed the microbial communities of omnivorous cockroaches collected from external environments and those reared in a clean laboratory for extended periods (5–20 years). Using the iSeq 100 system, we examined the relative abundance of microbial communities at the phylum, family and genus levels. Our results revealed that the predominant taxa in these cockroaches were Proteobacteria, Bacteroidetes and Firmicutes. Interestingly, the bacterial communities of samples from the same cockroach species, regardless of their living conditions, clustered together, indicating species‐specific similarities in microbiomes. The symbiont genus Blattabacterium was consistently present in all samples, delivering nutrients to the host. Pathogen detection at the genus level indicated a higher prevalence of potential pathogens in cockroaches collected from field environments, compared with those from laboratory‐reared cockroaches. These findings underscore the importance of cockroaches as pathogen reservoirs and vectors of opportunistic infections, emphasizing the need for further studies to identify specific microorganisms and confirm their pathogenicity. As cockroaches inhabit human environments, their potential to spread harmful bacteria through defecation warrants attention and underscores the significance of understanding their microbial ecology for public health implications.
