Bell Laboratories Contrac Blox Rodenticide 18 lb pail — brodifacoum single‑feed ready‑to‑use blocks

Contrac Blox Rodenticide is an 18 lb pail of ready-to-use, brodifacoum-based bait blocks engineered for dependable, long-duration control of mice and rats in commercial and residential settings.

Designed by Bell Laboratories, Contrac Blox delivers a high-potency anticoagulant formula in durable block form that resists weathering and chewing. The bait is formulated to remain palatable to rodents while minimizing the need for frequent replenishment. This product is intended for use inside and around structures where rodent activity is evident, applied according to label directions and local regulations.

How do Contrac Blox blocks work to control rodent populations?

Contrac Blox contain brodifacoum, an anticoagulant active ingredient that interferes with blood clotting after rodents ingest the bait. Because the blocks are highly appealing, rodents consume a lethal dose after one or a few feedings, which helps reduce populations without constant rebaiting.

• Single-feed potency reduces the number of feedings required.
• Durable block form resists crumbling and moisture.
• Strong palatability encourages consumption over alternate food sources.
• Suitable for placement in tamper-resistant bait stations.

Where and how should I place the 18 lb pail of bait for best results?

Place Contrac Blox in areas with signs of rodent activity—along walls, near burrows, in attics, basements, or inside secure bait stations. Follow the product label for spacing and quantity recommendations and always use tamper-resistant stations in public or occupied areas.

• Locate stations every 10–20 feet where activity is concentrated.
• Use indoors or in protected outdoor locations to avoid weather exposure.
• Check bait stations regularly and replace consumed blocks as needed.
• Dispose of carcasses and used material per local rules and label instructions.

What safety and regulatory steps should I follow when using Contrac Blox?

Handle rodenticide with care: wear gloves when placing bait, keep product out of reach of children and pets, and install bait inside locked or tamper-resistant stations in accessible areas. Read and follow the entire label for first aid, storage, disposal, and legal compliance.

• Store the sealed pail in a locked, dry location away from food and feed.
• Use gloves and wash hands after handling bait.
• Keep bait stations labeled and secured against non-target access.
• Follow local requirements for anticoagulant rodenticide use and reporting.

How long will a single 18 lb pail last for routine pest control needs?

Longevity depends on infestation size and placement frequency; a well-placed pail used for regular maintenance in low-to-moderate infestations can supply many weeks or months of bait. For heavy infestations, more frequent replacement or multiple pails may be necessary.

• Low-level maintenance: one pail can last several months.
• Moderate infestations: plan for more frequent station checks and refills.
• Severe infestations: combine with exclusion and sanitation for faster results.
• Record usage to predict refill timing and inventory needs.

Who is this product for? Contrac Blox Rodenticide in the 18 lb pail is aimed at pest management professionals, facility managers, farmers, and homeowners who require a high-efficacy anticoagulant bait for persistent rodent issues. It suits users who can comply with label directions and safety protocols, have access to tamper-resistant baiting systems, and need a bulk, long-lasting supply for recurring control or large properties.
