Data for non-target interactions and humaneness evaluation on a captive-bolt trap for commensal rodents

Little research has examined the humaneness of the trap or its potential to harm non-target mammals and birds. This study aimed to identify potential risks to non-target animals. 17 traps, each paired with a motion-activated video camera, were deployed at two sites where rodents were present.

In a nine-week study, traps were baited but not activated, and a blocking device (“blocker”) was used in a cross-over design to evaluate its potential at reducing non-target strikes. Once the researchers were confident in avoiding non-target strikes, the traps were activated and recorded for 19 weeks across two different locations to evaluate humaneness. Surprisingly, only 11 trap triggers and eight kills were observed across the two locations.
