Designed with technicians in mind, 1-lb. City Packs for CONTRAC and FINAL BLOX are available through Bell Laboratories’ distributors. City Packs feature lightweight pouch packaging for easy transportation. The smaller pack size is useful to control inventory in the field, the company says, and has a zip-lock closure to keep bait fresh. CONTRAC’s bromadiolone formula is known for rodent acceptance and control. FINAL All-Weather BLOX contains brodifacoum, considered by many to be the strongest single-feeding anticoagulant on the market today. CONTRAC and FINAL City Packs are approved for use on commensal rodents as well as meadow voles and seven other additional species (certain restrictions may apply). CONTRAC City Packs are also approved for use on Peromyscus spp. (deer mouse, cotton mouse and white-footed mouse).
