Bees are important pollinators of wild and domesticated flowering plant species. Over the last 30 years, an increasing number of scientific articles have been published on the ecology and conservation of wild bees. To achieve research goals, many studies have pursued the lethal take of wild bees. Although the impact of lethal take for scientific pursuits is likely negligible compared to the negative impacts of human‐mediated phenomena such as climate change, urbanization, and agricultural intensification, it is important to evaluate the history of lethal take on scientific endeavors. In our study, we evaluated a random sample of 30 years of scientific publications on wild bees. Across 1426 surveyed publications, 536 reported the lethal take of wild bees. We found that 61% of these studies lethally captured wild bees primarily for species identification. Furthermore, we determined passive sampling of wild bees resulted in substantially more lethal collections than active methods per study. However, combined approaches of passive and active collection resulted in the greatest lethal take of wild bees per study. Finally, we determined that 64% of the studies did not provide deposition information for their samples, hindering additional research that could be done with them. The increasing availability of video and photographic devices and artificial intelligence approaches to identification, the development of low and noninvasive molecular methods, and the ease of sharing information, allow for a timely discussion on alternative routes and potentially new best practices in bee research. We focus our discussion on alternative methods for minimizing lethal captures for identification purposes and through passive methods, and for maximizing the utility of the data collected. Finally, we provide a framework for continued engagement among researchers and managers to develop strategies that can contribute to reducing our impact on wild bee communities and making the most of collected specimens. To achieve research goals, many studies have pursued the lethal capture of wild bees. We conducted a literature search of last 30 years of scientific research on wild bees and we found that 61% of studies (from a random sample of the total) lethally captured wild bees, primarily for species identification and with passive sampling methods. We then discuss the current available alternative methods for minimizing lethal captures and maximizing the utility of the data collected
