Bears crave beaver and will often pass up food and other bait sources for the scent of fresh castor. Code Blue's new Bear Magnet Power Start Drip Bag contains field tested aromas and flavors infused with the scent of real beaver castor. Power start early season bait sites using the smell of fresh beaver to initiate feeding. The intense castor scent lures bears incredibly close and keeps them coming back for more. Plus, the two pound bag lasts for months!
