Customer Reviews for Contrac All-Weather Blox Rodenticide

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?

  Expert response:
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.

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@!.

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!!!!!!!!!!!!!!

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

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.

I have a rat phobia and NEEDED a product that worked. Contrac-Blox is it! One problem, though. I live in an avocado grove and had a bad infestation. Each morning, all six boxes of poison was empty and I would fill them up daily. When the UNTOLD NUMBER of rats began dying a few days later, my property smelled horrible for two weeks. Simple fix: With a bad infestation, only replace the bait every four or five days or use less bait stations. That should meter the number of dead rats and any given time to minimize any unfavorable odors. It might take an extra week or two to kill them all, but the olfactory aesthetics might be worth it! Bottom line: Contrac-Blox works very well, just don't overuse it, or it works TOO well!!! And, that is good!

Mice became "midnight visitors" in our custom house, along with our neighbors, once a large tree near our property was felled. On our block, we just don't get mice, or any other unwanted intruders, so we became unsettled thinking we were living among these little guys. We tried havahart traps, tin-cats, snap traps, just about the whole kitchen sink but we still saw one or two around, knowing that meant there were many more nearby. We hired not one, but 2 exterminators on several different occasions who assured us that their poison (Warfarin) would do the trick. Again, it helped a little, but there was more work to be done. These "blox" did it. 10 days, no more mice. It's that simple. We didn't want to poison them, but at some point, knowing they were living amongst us and seeing droppings in our baby's room sealed the deal. If you truly want to be rid of "tough" resistant NYC mice, this is the product. Hands down.

The Contrac Blox Rodenticide is keeping rats out of my house and out of my yard. It is easy to use, and rats love it. An additional benefit (in my opinion) is that small ground squirrels which were undermining my hill, worked their way into one of the bait stations and the Contrac blox got rid of them as well.

I left a somewhat negative review of this product and I believe it was premature. I thought the product didn't work because I still had a rat problem but discovered that my husband did not finish the product per the instructions. We also live in a major city so we have neighbors that you rely on to help out with the problem also. I had him finish what we had left and the infestation diminished greatly! We still had some huge poppa rats around and no more product left so we put a couple of traps and caught the two head honcho rats who may have been too fat for the poison to take effect. It has been over 2 weeks now and not one rat has been seen. We went from seeing 15 rats per day, to none. We even put food out there to test it for a few days and still, not one rat. I wish I could delete my previous review. I think this product works very well. Thank you, I hope this helps others. I would purchase this product again.

I had huge rats and mice running all over my house. It was so many of them. We got this product and within a week I haven't seen a thing. We purposely left food on the table overnight but everything stayed untouched. THEY ARE GONE. The product worked 100%.

A great choice for most all rodent jobs. I've used this in my company for many years with no problems. If the blocks set out for a while and mice/rats stop feeding on them, just take a knife and slightly trim each side of the block.

Great value - great product. I use this to rid my property of grey squirels and chipmunks, and it works great. This is the only product I have found that is tempting to chipmunks. Works great!

I used to buy Contrac Blox in the store, but had not been able to find it.  It is the best mouse poison.  I hate to poison them, but we have camps and they ruin everything. I am so happy to have found it online.  It is the only poison that works well for my sisters and me [3 camps]. The mice that is!

I place Contrac in my bait stations with Final. Rodents seem to prefer the Final over the Contrac but, they still eat the Contrac, which does a very effective job, and I like to give the rodents on my farm a choice of their poison.

I have been using this product for over five years. I haven't had any mice in the house during this time frame. An important feature for me is that it is pet safe.

I bought an 18 lb bucket and six stations two years ago. I have not had a problem with the bait going stale, but I will replace a 1/2 eaten block if it's old. We had Norway rats and mice in our house after we moved in. I put the bait out, and within two weeks the signs of rats/mice were gone. We have had no trouble with rodents since then, but there is activity outside the house often. I check the bait stations every weekend during higher activity times of the year, and once every couple of weeks in lower activity times of the year. At this rate, we use an 18 lb bucket every two years.

Fast delivery and great price. Great for a do it yourselfer like me. Less than the cost of two visits from a professional. This product works well and is used by professionals. Be sure to use a bait box to keep other animals safe. Wear gloves.

First I tried traps, then I tried drowning them, then I tried a first generation poison; then I found Contrac. I am delighted with the product. You can break the blocks in half, cover them with a thin smear of peanut butter and ground squirrels will actually fight over who gets to eat the product. I think they're gone from my property but it appears I might be getting a few from neighboring properties so I'm doing a fall and spring "get rid of them" campaign. Be sure to wear "rubber" gloves.

This product works well, we see very little activity going on within the bait stations, and have not seen signs of rodents inside our shop after giving this product time to work. This is our second purchase of this product and we will continue using it.

I was very concerned because, for the first time in 45 years, a nest of rats was established under the stoop of my Brooklyn row house. The Contrac Blox I ordered arrived promptly -- and a "meal" was immediately set out for the unwelcome visitors. Within a week, I was able to remove 3 corpses -- and all activity seems to have ceased. The stuff works!

We have been using Contrac Blox Rodenticide for a year and just purchased a second pail of Blox. We live in the country and this product has done a good job of keeping the ground squirrels and mice away from the house. If we don't have the Blox out the rodents are at the front door, in the garage and under foot.

I had used the Contrac before with good results. I switched to Terad to save money due to the larger qty requirement of Contrac. Terrible results from Terad. Switched back to Contrac after my rodent problem got bad again. Instant results. Within days dead rats began to show up. Can't beat it.
