What is an important factor for the effectiveness of rodenticide tracking powders?

The effectiveness of rodenticide tracking powders is significantly influenced by the concentration of the active ingredient. A relatively high concentration is crucial because it ensures that the rodent consumes a lethal dose when it ingests the bait. This high concentration enhances the potency of the powder, making it more likely that rodents will be affected quickly after contact. Since tracking powders are designed to be fine and adhere to the fur of rodents as they move through treated areas, having a higher concentration amplifies the likelihood of effective control by maximizing the amount of poison that enters the rodent's system.

Conversely, a low concentration of the active ingredient would diminish the effectiveness, as it may not provide a sufficient dose to kill rodents or could lead to sublethal effects, allowing them to survive and potentially develop resistance. Additionally, the presence of active ingredients is paramount; without them, the product would not serve its intended purpose, and the formulation's natural materials would not replace the need for a toxic element in controlling rodent populations. It's the balance and potency of the active ingredient that are essential for achieving effective rodent control.
