Highly palatable to ground squirrels, this bait is pelletized to emulate their natural food source and encourage them to eat the bait, not to store it. It contains the anticoagulant Diphacinone (.005%) and is a multiple-feed solution requiring the pocket gopher to consume 3-4 days of continuous feeding. This homeowner bait is available in 4 lbs. and 20 lbs. No permit and/or license is required.
