The kit includes NB Tube Bait, which is a rich mix of nut oils, meats and seeds in a convenient tube that squirrels find irresistible, the company says. It also includes a new Paste Bait Gun (WCS101504) for added convenience. NB Tube Bait, like all of the “Premium Grade” bait products, is spiked with an anti-drying agent to increase the bait’s effectiveness. NB has proven itself effective with chipmunk, gray, red and flying squirrel species. For a change-up bait, give it a try on Norway rats and mice.
