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.
Note: Due to California state restrictions, this product cannot be sold to California residents.

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 mouse bait stations or rat bait stations, or nail or wire it in place.
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.
Mice like it. But...
By Robert on 02/24/2009
I live in a row-house and have an 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?

This stuff is the best!

Living in a restaurant filled neighborhood in DC with unkempt neighbors on both sides of our house led to our backyard becoming a rat highway. It got so bad that we would have 6 or 7 running across every 5 mins. all night - and they were getting closer and closer to the house. We looked at all kinds of new fencing options only to realize it wouldn't have made a difference since they'd probably just burrow underneath it. We bought this and in less than 1 week's time, we have abolished every rat! We only had one meet his maker in the yard that we had to dispose of, the other hundred or so wandered off to die. It's been close a month now and we still have not seen one. This stuff is BAD A@!.

The "TRUTH"
By Tarik on 03/13/2010
Verified Purchase
This stuff is the truth. I've tried the Rex traps and other traps but those other methods just didn't get the job done. I live in a duplex with joining garages and my neighbor had dog food which attracted the rats. They were multiplying faster than I could trap them. I bought Contrac and placed them in stacks of three around my garage also stacked six of them where the garages joined. The next day the six were gone. I replaced the six with six more, they disappeared. Within five days not a sign of rats or droppings. I didn't even have to dispose of the dead rats. This is a winner!!!!!!!!!!!!!!

Best I have seen
By Harold on 11/09/2006
This is the best I have seen. I had a bucket of Contrac Blox rodenticide sitting in the barn and the rats ate a hole in the top of the bucket.

Bait stations are placed in the yard to deal with rats. Bait stations will be found 3 to 4 feet from where they were placed and bait is gone. I do not want to attract racoons or other critters. Should a different bait be considered or should I not bait the traps for some period of time?

I don't want to host the rat colony on great tasting food. I will never get rid of them. Please help and explain how to handle this
Contrac Rodenticide doesn't so much attract rodents from all over as it will target rodents that are already coming onto the property other food sources, nesting supplies or water. Bait stations with rodenticides should be placed on the exterior of the home or within 50ft of the house where the rodents are already traveling. The blend of food grade ingredients will appeal to their sense of smell as they travel along their already familiar path. Use gloves when handling the bait so your human scent does not contaminate the bait and place the bait stations in the runways they are already traveling. Bait should be renewed at intervals of several days. Continuous bait availability (as with anticoagulants) is not required, but bait needs to be present long enough to allow all animals in the area to feed. The amount of bait needed is usually about one-third that used with anticoagulants, since an animal ingesting a lethal dose does not feed again.

I have Contrac Blox Rodenticide inside Protecta Evo Ambush bait stations, and it appears that insects are eating the bait. I put these out last year, and I didn't notice any signs of insects eating the bait at that time (I change the bait every 4 months). Recently, all of the bait was gone, and I replaced it and rechecked the next week to find them covered in insects. Any ideas/suggestions?

Contrac Blox Rodenticide should be applied in tamper resistant stations to avoid non-target animals and children from accessing the bait inside. It is possible that a squirrel could be attracted to the bait for consumption. Although, Contrac is labeled for rats and mice, it could harm a squirrel as well since they are also in the rodent family.

I put some in a ceiling of a horse barn where the rats are nesting and I am finding some in the stalls. The rats are carrying them out of the ceiling and dropping them in the stalls. I was wondering what would happen if a horse ate one and if he would?

I'm in pest control and have went back to this job numerous times they have no food laying around and there is no feeding on the contrac blox I'm stumped they won't even go for snap traps...
There are many reasons why rodents may not be attracted to a bait such as Contrac Blox. One very common reason is that the bait is not fresh; baits should be used within 1 year of opening, and stations should be changed every 30 days for the best acceptance. You should also be sure to wear gloves when servicing bait stations and handling rodenticides. This not only protects the person handling the bait and stations from contaminants and possible disease, but it also keeps human scent and oils off the bait so as not to deter the rodents from it.
It can be difficult to locate competing food sources. Mice will travel up to about 10-20 feet for food from their nesting site, while rats will travel much farther, 50-100 feet from their nesting site. Bait placements should be close enough together to allow easy access to the bait. Keep in mind also that if this is a service call, then you have not been there to monitor the sanitation all the time, so there could be trash or other food sources that have been left out. All food storage areas, food containers, areas around applicances, and trash receptacles should be checked for rodent activity.
If you have used fresh bait multiple times and are unable to locate and competing food sources but still see new rodent activity, then you may want to consider using a different bait. Just like people, rodents can prefer one food over another. Soft Baits such as First Strike have very high palatability and are great to rotate with something like Contrac.
