It is recommended to replace any moldy or soggy bait blox in tamper resistant bait stations as the bait matrix is no longer palatable to rodents. It is suggested to replace uneaten or remaining rodent bait such as Fastrac All-Weather Blox Rodenticide atleast once a month to ensure fresh bait is being offered consistently. Please view our Rodent Treatment Guide and Rodent Baiting Failure Article for more information.
