Which method is less effective for controlling rodent populations?

Using only large bait placements is less effective for controlling rodent populations because it does not consider the feeding behavior and habits of rodents. Rodents tend to be cautious when encountering new food sources, and they often prefer small, scattered bait placements that are less conspicuous. Large bait placements might attract rodents initially, but they can also make them wary, leading to reduced bait consumption.

Additionally, effective rodent control relies on a combination of methods including trapping, consistent bait placements, and eliminating food sources. By addressing these other factors, pest control efforts can be more comprehensive and efficient. Relying solely on large bait placements may overlook the importance of strategic placement and the rodents' natural cautiousness, making it an inadequate standalone method.
