• Contrac All-Weather Blox – 18 lb Pail

Bell Labs - Contrac All-Weather Blox – 18 lb Pail

Contrac All-weather Blox Rodenticide is a multi-edged, single feeding Rat and Mouse bait. It is formulated with an optimal blend of food grade ingredients and low wax to yield a highly palatable, weatherable bait that is very attractive to rodents. Secondary poisoning is very minimal with Contrac as an antidote to the poison (vitamin K1) is readily available. We recommend placing the blox in tamper resistant mouse bait stations or rat bait stations to protect the bait from non-target animals such as dogs and cats.

Containing the active ingredient, Bromadiolone, CONTRAC All-Weather BLOX rodenticide is a single-feeding anticoagulant rodenticide. CONTRAC BLOX  is specially formulated with a blend paraffin and food-grade ingredients.

Time tested rodent acceptance and control due to its highly palatable formulation, CONTRAC BLOX rodenticide is an excellent clean-out and maintenance bait to control mice and rats, including warfarin-resistant Norway rats.

For ease of use, a hole in the center of the BLOX lets technicians place it on bait securing rods in tamper-resistant bait stations, or nail or wire the BLOX in place.

  • CONTRAC 28 gm BLOX works well in tight places, nailed to rafters or ceilings, or in Bell's tamper-resistant bait stations.
  • Palatable, yet weatherable, CONTRAC works well in wet and dry conditions.
  • Multiple edges attracts rodent's desire to gnaw.
  • Bait shyness is not an issue with CONTRAC because mortality occurs a few days after bait is consumed. 

Use: Around homes, food processing facilities, industrial and commercial buildings, trash receptacles, agricultural and public buildings, transport vehicles and other listed uses.

Also available in: 4 lb pail, 1 lb City Pack


Active Ingredient:

Bromadiolone .005%

Norway Rats, Roof Rats, House Mice, Meadow Voles

For use in:

Agricultural and animal production facilities, warehousing and food processing plants, as well as for commercial, industrial, and residential accounts


Recommend changing bait out every 40-60 days if not eaten. Very cold or warm temperatures will mold or sour the bait faster. Apply bait in locations out of reach of children, pets, domestic animals and nontarget wildlife, or in tamper-resistant bait stations.

Pet safe:

Contrac is LESS toxic to non-target animals in both primary and secondary poisoning situations than other single-feeding baits. An antidote, Vitamin K1 is readily available and there is a time factor for treatment. Used in tamper resistant bait stations or areas inaccessible to non target animals and children.
