Abstrakt: Background: Snap traps and electronic traps are the main devices for nonchemical management of rodent pests. Traps should be efficient and should not cause unnecessary suffering of animals. Harmonized, systematic test methods are required to make sure that mechanical forces or electrical parameters are optimal to achieve swift unconsciousness and death. This study aimed to describe technical trap properties that can be used to facilitate future improvements in trap efficacy and humaneness.
Methods: We constructed a device to assess spring energy, triggering force, impulse and clamping force, and developed an arrangement to assess effective voltage, current, effective current and effective energy taking effect on rodent bodies in electronic traps - all without the use of animals. Descriptive data of trap characteristics were collated.
Results: All factors showed variability among snap trap models and trigger types, and there was considerable overlap between mouse and rat traps. For most trap models, there was no difference among new snap traps and traps that had been trigged 20 times. Effective current and effective energy decreased with lower voltage input, but the traps indicated weak battery by LED lights, and one model switched off automatically when voltage was insufficient.
Conclusion: With the device and the electronic arrangement, the majority of snap trap models and electronic traps available on the market can be assessed in a standardized and repeatable way. Matching the data generated in this study with data on time for trapped target animals to reach irreversible unconsciousness, and experiences from pest control practitioners, should allow relating properties of traps to efficacy and animal welfare issues. This can support further development and optimization of traps for nonchemical rodent pest control. © 2024 Julius Kuehn-Institut and The Authors.
