What makes extruded blocks a leading choice for rodent control?

Extruded blocks are a leading choice for rodent control primarily because they are designed to withstand various environmental conditions, making them effective for use in both indoor and outdoor settings. This durability is essential when dealing with rodent populations that may inhabit diverse environments, as it allows the bait to remain intact and functional over time without degrading due to moisture or other factors.

This characteristic enhances their effectiveness in controlling rodent populations since the blocks remain accessible to rodents without losing their appeal or potency, even in challenging conditions such as wet or humid environments. Robustness ensures that the bait can be deployed in a range of locations, ensuring broader coverage and consistent performance.

The other options do not align as accurately with the primary advantages of extruded blocks in rodent control. While cost-effectiveness and ease of manufacturing are important factors in pest control products, they do not directly contribute to the efficacy of the product in the field. Additionally, toxicity levels are a crucial consideration, but the primary reason for using extruded blocks hinges on their resilience and effectiveness across different environments.
