What bait should be used in rodent bait stations in areas with regular overhead irrigation activity?

Using wax block bait in rodent bait stations located in areas with regular overhead irrigation activity is advantageous because this type of bait is less likely to be compromised by moisture. Wax blocks are formulated to resist water, maintaining their effectiveness even when exposed to wet conditions, which can be common around irrigation systems.

Liquid baits and granular baits are susceptible to being washed away or losing their efficacy when exposed to water, as their formulations are not designed to withstand exposure to moisture efficiently. Pellet bait can also degrade when wet, potentially leading to a loss of palatability and effectiveness. Thus, wax block bait is the preferred choice in this scenario, as it ensures that the bait remains accessible and attractive to rodents even with the presence of irrigation activities.
