Effective rodent management requires a strategic approach grounded in real activity, account sensitivity and long-term prevention. BASF’s switch approach is two-fold: Prelontra Rodent Monitoring Soft Block helps determine when to monitor, when to activate control and how to help reduce the risk of future infestations. When used alongside Selontra Rodent Bait, Prelontra supports a flexible, informed framework for managing rodent pressure across a range of account types.
The direct Selontra switch is best suited for accounts where rodent activity is already confirmed, and rapid population reduction is the priority. Selontra features a non-anticoagulant mode of action that helps combat resistant rodents and stops feeding after a lethal dose. Its active ingredient, cholecalciferol, also helps reduce the risk of secondary toxicity to non-target animals, which is an increasingly important consideration as regulatory attention continues to grow. For best results, success should be measured by activity reduction, not bait consumption alone.
Prelontra offers a more measured path for sensitive environments, rodenticide-restricted accounts, or situations where neophobia may slow bait acceptance. As a non-toxic monitoring soft block, it verifies feeding, identifies pressure zones and helps build feeding confidence before Selontra is introduced. After control is achieved, rotating back to Prelontra supports continuous monitoring and prevention. Together, Prelontra and Selontra give professionals a practical switch strategy for smarter, more sustainable rodent management.
