New Premier Formulation with Vitamin D3 TERAD3 BLOX, Bell's newest rodenticide, expertly combines the most recent advancements in bait formulation to yield a highly weatherable BLOX with the low hazard benefits of the active ingredient, Vitamin D3. After years of researching the most effective formulation for housing this unique active ingredient, Bell scientists have found the perfect match - a denser, tightly compacted 1-oz. extruded BLOX with superb durability and weatherability. Incorporating an advanced preservation system, TERAD3 BLOX is mold and moisture resistant. Its high melting point keeps the bait stable in temperatures as high as 200 degrees F. Equally outstanding is the bait's palatability. TERAD3 also has a recognized stop-feed action, reducing the need for extensive and continued bait. Ultimately this results in lower total bait consumption with greater cost savings. TERAD3 BLOX with Vitamin D3 kills anticoagulant-resistant rats and mice yet substantially reduces the risk of secondary poisoning. It also poses low toxicity to birds. With BLOX, bait translocation is also reduced. TERAD3 BLOX has a broad label which makes it an excellent choice for controlling rodents at agricultural and animal production facilities, warehousing and food processing plants, as well as for commercial and residential accounts.
