Provides effective rodent control for high populations and severe infestations using bromethalin, an acute non anticoagulant active ingredient. The bait begins working in as little as 2 days after a lethal dose is consumed and works by disrupting the rodents nervous system. The uniquely shaped bait chunx feature multiple edges that encourage gnawing and are made with food grade ingredients for strong palatability. Low wax content provides good weatherability while helping resist mold and moisture. Each block includes holes for use with bait station rods or can be secured with nails or wire. One block can kill up to 12 mice based on laboratory testing.
