The patented Recruit HD termite bait is featured in the Sentricon System with Always Active technology. Its formulation uses a highly dense cellulose bait matrix containing noviflumuron as its active ingredient. In field research, the bait formulation has remained effective for nearly a decade. It has also been found to become more palatable to termites as it ages in Sentricon stations. As the only termite bait labeled for an annual service schedule, each Recruit HD bait contains 150 grams of bait material.
