Rodenticides are considered more practical for which type of rodent pests?

Rodenticides are considered more practical for smaller rodent pests like voles because these substances are specifically designed to target rodents that meet particular size and behavioral characteristics. Smaller rodents typically have higher populations and can reproduce rapidly, making them more susceptible to control measures such as poison. Moreover, these smaller pests often inhabit environments where open bait stations can be effectively utilized without alerting larger animals or pets.

In contrast, larger rodents, wild birds, and domestic pets are not suitable targets for rodenticides due to differences in their biology and feeding behaviors. Larger rodents, for instance, may require different control methods, while wild birds and pets are protected under various regulations and are not appropriate for rodenticide applications, as they could suffer harmful effects from these chemicals. Thus, the practicality of using rodenticides is significantly higher with smaller rodent pests like voles.
