Which option highlights a benefit of trapping over using rodenticides?

Trapping offers several advantages over rodenticides, particularly in terms of safety. One significant benefit is that trapping avoids the various risks associated with rodenticides, which can be hazardous to non-target animals, pets, and even humans if not handled properly. Rodenticides can lead to secondary poisoning, where predators, scavengers, or pets consume a poisoned rodent and suffer harmful effects. In contrast, traps capture rodents directly without introducing toxic substances into the environment. This not only enhances safety but also allows for better control and monitoring of rodent populations without the associated risks of chemical exposure.

The other options do not accurately represent the primary advantages of trapping. For instance, trapping does not inherently provide a longer-lasting effect compared to rodenticides, which might have residual effects even after initial application. Additionally, while trapping could be considered easier in some contexts, it is not universally true and often depends on the specific situation or type of trap used. Finally, traps do not attract more rodents; they are designed to catch those that are already present, rather than to lure additional rodents. Thus, avoiding the risks associated with rodenticides is a key benefit of using traps in pest control.
