Abstract The behavioural responses of Cryptolestes pusillus, Oryzaephilus surinamensis and Prostephanus truncatus to different doses of carob extract were assessed in a two‐choice pitfall bioassay and in plastic grain probe traps. The extract evoked a quick directional response and induced high beetle attraction to treated pitfall arenas compared with the controls. Overall, the extract improved probe trap efficiency by about 50% compared to unbaited probes. Beetle response was dose‐dependent with the medium dose of 10 μl probably eliciting optimum response.
