Field tests of a warfarin gel bait for moles

This paper discusses the more common methods of mole control used in the U.S. Field efficacy data are presented with a new product, Kaput® Mole Gel Bait, containing 250 ppm warfarin. Initial field studies in St. Louis, MO with a 500-ppm warfarin bait in 1998 yielded 50% efficacy within 5 days. The following year, a 250-ppm warfarin gel bait yielded 85% efficacy after 7 days of application. Field tests conducted in Ohio resulted in 90% control of eastern moles. Results from a field test in Oregon using warfarin alternate formulation and diphacinone gel baits demonstrated 47% and 80% control of Townsend’s mole within 15 and 7 days respectively.
