• Contrac All-Weather Blox – 4 lbs per pail, 4 pails per case

Bell Labs - Contrac All-Weather Blox – 4 lbs per pail - 4 pails per case lot


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.

Active Ingredient:

Bromadiolone .005%

Target pests:

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.


Each 4 lb. pail contains approx. 64 (28 gram ea) 2 in. x 1 in. x 1 in. blox.
Each 18 lb. pail contains about 288 blox.



Shelf Life:

If unopened and sealed, product will last 2-3 years if kept away from extreme temperatures. Once opened, should last a year in normal conditions

Coverage Area:

All bait placements must be inside or within 50 feet of buildings.
