Provides an effective liquid bait option for controlling Norway rats, roof rats, and house mice using diphacinone, a multiple feed anticoagulant active ingredient. Each pouch mixes with 1 quart of water to create a liquid bait that can supplement a rodent control program, especially during hot and dry conditions when rodents seek additional water sources. The mixed solution can be placed in a chicken feeder or other suitable container where rodents are likely to seek water.
