Contrac All-Weather BLOX Rat Bait 18 lb Pail - Reliable Control

In this review of the Contrac All-Weather BLOX 18 lb pail, the bottom line is simple: pest control professionals and serious DIYers looking for a weather-resistant, highly palatable rodent bait will find this product effective for clean-outs and maintenance. The reviewer found the BLOX design makes placement straightforward in tamper-resistant stations or when nailed in place, and the bromadiolone formulation provides single-feed anticoagulant action that works on warfarin-resistant Norway rats and common mice problems.

Key Features

• Center hole design: A preformed hole lets technicians mount each BLOX on bait rods or secure them with nails or wire for stable placement in bait stations.
• Highly palatable formula: Manufactured with a food-grade blend and extrusion process, the bait attracts rodents quickly and encourages gnawing on multiple edges.
• Weatherable composition: The small amount of paraffin and extrusion shape make the BLOX resistant to wet and dry conditions, extending field life outdoors.
• Single-feed anticoagulant: Contains bromadiolone to deliver single-feed control effective against warfarin-resistant Norway rats and other target rodents.
• Easy maintenance use: Works well as both a clean-out bait after infestations and for ongoing maintenance due to strong acceptance by rodents.

Who It's For

This product suits pest control technicians, property managers, and homeowners who need a durable, easy-to-place bait for heavy infestations or routine maintenance. The design favors those who use tamper-resistant bait stations or who secure individual blocks with nails or wires in protected locations.

It is less suitable for casual users who prefer non-chemical traps or for situations where anticoagulant baits are restricted; always follow local regulations and keep bait out of reach of children and non-target animals.

Pros & Cons

Pros

• Highly attractive formulation leads to fast acceptance and effective control in days for many users.
