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 and an antidote to the poison (vitamin K1) is readily available. We recommend placing the blox in tamper resistant bait stations to protect the bait from non-target animals such as dogs and cats.
Active Ingredient:
Bromadiolone .005%
Target pests:
rodents
For use in:
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.
Application:
Recommend changing bait out every 40-60 days if not eaten. Very cold or warm temperatures will mold or sour the bait faster.
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.
DESCRIPTION: 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. Contrac® All-weather Blox® contains Bromadiolone, which is less toxic to non-target animals in primary and secondary poisoning.
USE: Baits are small 1 oz. size and can be placed in bait stations, in holes and burrows, or where mice and rats tend to travel. A hole in the center of each block allows it to be placed on bait securing rods in tamper resistant bait stations, or nail or wire it in place.
NOT FOR SALE IN: AK
Ready-to-use CONTRAC BLOX bait pieces feature a patented multi-edge design that gives rodents plenty of gnawing edges per piece. The 1-oz. bait pieces fit easily into burrows, bait stations and tight baiting places. A hole through the center lets you wire/hang the bait, or place on bait securing rods for added security.
It is colored blue and authorized by USDA for use in federally inspected meat and poultry plants.
Do not place bait in areas where there is a possibility of contaminating food or surfaces that come in direct contact with food. Do not broadcast bait.
SELECTION OF TREATMENT AREAS: Determine areas where rats or mice will most likely find and consume the bait. Generally, these areas are along walls, by gnawed openings, in or beside burrows, in corners and concealed places, between floors and walls, or in locations where rodents or their signs have been seen. Remove as much alternative food as possible.
Norway rats and house mice may consume a lethal dose in one feeding with first dead rodents appearing four to five days after treatment begins.
DIRECTIONS FOR USE
APPLICATION DIRECTIONS: Each bait block in this container weighs approximately one ounce. RATS: Place 3 to 16 CONTRAC BLOX (usually at intervals of 15 to 30 feet) per placement. Maintain an uninterrupted supply of fresh bait for at least 10 days or until signs of rat activity cease. MICE: Place 1 block per placement. Space placements at 8- to 12- foot intervals. Two CONTRAC BLOX may be needed at points of very high mouse activity. Maintain an uninterrupted supply of fresh bait for at least 15 days or until signs of mouse activity cease. RATS AND MICE: Replace contaminated or spoiled bait immediately. Collect and dispose of all dead animals and leftover bait properly. To prevent reinfestation, limit sources of rodent food, water, and harborage as much as possible. If reinfestation does occur, repeat treatment. Where a continuous source of infestation is present, establish permanent bait stations and replenish as needed.
I live in a rowhouse and have a on and off again love-hate relationship with mice. They love me. I hate them. I put these Contrac Blox in my detached garage and almost every morning they are nibbled at. (there is a field behind the garages) They eat it but is it true that if the bait goes stale you have to throw it out? Does it become ineffective? How long? Is there an expiration date on the pail? I would hate to buy the 18 lb size and then have to throw most of it out. help?

Staff recommendation:
The fact that the bait is being eaten every day is a good sign. Mice will not die immediately after eating rodenticide baits, and will probably die somewhere out in the field on their way back to the burrow. Contrac lasts about 2 years in the bucket. When placing the bait, the manufacturer recommends that the bait be changed out every 40-60 days.

I used this product with no results. You could see where the mice were eating it but I never found any dead mice.

Staff recommendation:
You may not see dead mice as they may not die where the bait is eaten. Rats and mice usually die within a few days. This is true for almost all anti-coagulant rat and mouse baits such as Contrac. Also, if the rodents are just nibbling, you need to keep plenty of the bait available to ensure a lethal dose.
Works very well at reducing mice population, December 12, 2008
By Bill from New York, NY
Contrac Blox Rodenticide works very well in reducing the mouse population. However, I have not been able to rid myself of mice completely. It has been 3 months and I have put out more bait and thrown out stale bait. How long before the bait gets stale anyway? Any tips from anyone would be appreciated.

Since it is a food source, bait will spoil. A cool and dry environment will help prolong the shelf life.

We were getting rundown with field mice from the lot next to our home. Traps were not getting the job done. After 2 weeks using Contrac Blox Rodenticide the mice were gone....Thanx
I live in a mobile home and I purchased Contrac Blox and scattered it under my home. What happens to the mice after they eat it? How long does it take for them to die? Do they need water for this product to work?
Contrac Blox is an anti-coagulant which means once the mice eat this product they begin to bleed to death from the inside. The mice first become sick, and then grow tired and weak and pass in their sleep. It can take anywhere from a few hours to a few days depending on how much the mice have eaten. They do not need water for the product to work.
