Comparative assessments are needed to improve control plans and reduce the impact on honeybees and entomofauna. Our aims were to study the performance of traps and baits, to identify environmental conditions that affect capture rates and to identify the groups of insects affected by trapping. During spring in 2016, three types of trap and baits in a full factorial design were tested. Vespa velutina accounted for less than 1% of all captures, reflecting the low selectiveness of the method. The trap design and its location are decisive aspects to determine the capture rates of V. velutina queens. All trap-bait combinations captured a very high quantity of dipterans, native hymenopterans, and lepidopterans. High capture rates of insect groups which are not common prey of V. velutina reflect that the method constitutes an additional threat on native insects. apiculture / Apis mellifera / invasive species / pest management tools / yellow-legged hornet Electronic supplementary material The online version of this article (
