EPA Clarifies Rodenticide Label Revision

The Agency provided additional clarification relating to the use of first and second-generation anticoagulants and non-anticoagulants applied to rodent burrows.

April 2, 2012

On March 20, less than three weeks after EPA revised its 2008 RRMD for Professional Use Products, the Agency provided additional clarification relating to the use of first and second-generation anticoagulants and non-anticoagulants applied to rodent burrows. EPA specifies that the following language should appear on the revised labels:

•    On all second-generation anticoagulant products labeled for application in rodent burrow.
"This product may only be applied to active burrows to control Norway rats and roof rats within 100 feet of buildings and man-made structures constructed in a manner so as to be vulnerable to commensal rodent invasions and/or to harboring or attracting rodent infestations provided that infestations of these rodents have been confirmed. Efforts should be made to remove food trash, garbage, clutter, and debris."
"Bait must be placed no less than 6 inches into active Norway/roof rat burrows. Do not broadcast bait."
•   On all first-generation anticoagulants and non-anticoagulants professional and agricultural products labeled for application in rodent burrows: "This product may be applied to active rodent burrows to control Norway rats, and roof rats within or beyond 100 feet of buildings and man-made structures, provided that infestations of these rodents have been confirmed."
 "Bait must be placed no less than 6 inches into active Norway/roof rat burrows. Do not broadcast bait."
     "Because Norway/roof rat infestations may occur in areas farther than 100 feet from buildings and man-made structures when the rodents have ample supplies of food and cover, efforts should be made to remove food trash, garbage, clutter, and debris.”
