Contrac Blox - High Bait Acceptance With Rodent Control

Contrac Blox with bromadiolone has one of the highest bait acceptance of all our professional rodent baits. Bromadiolone is a single feed bait, that causes death after one feeding. Contrac Blox is the most palatable bait block on the market. Contrac Blox is made from a blend of food-grade ingredients with a paraffin coating. This process results in an all-weather bait that is highly palatable. It works in both dry and wet conditions. As one of the top products used by professionals, it has unsurpassed in rodent acceptance and control. Contrac Blox is popular as both a clean-out and maintenance rodent bait, working even against warfarin-resistant Norway rats.

Extrusion Process & Bait Shyness

Manufactured with Bell's extrusion process, Contrac Blox has multiple edges that appeal to a rodent's desire to gnaw. Rodents can consume a lethal dose in just one feeding. Bait shyness is not a problem with Contrac Rodenticide because mortality occurs a few days after bait is consumed.

Irresistible to mice and highly effective
This is a top notch product. I've tried alternatives from the big box stores and none come close to this product. We have two barns containing animals and feed supplies. I always keep my bait stations full. If just starting out, the mice will eat the bait pretty rapidly. However, this tapers off after a few weeks to minimal feeding, meaning your have rid most of the rodents. Don't let your bait stations go empty, or mice will return and multiply. I will never buy anything else and this is worth every penny.

The best rodenticide!
Great product. Rodents go for it!
I use 9 triple block bait stations on my rural property. I have not found a rodent dropping in my pump house, big shop or home. I set a box near my tractor and RV. Rarely find a carcass but the bait boxes are filled with droppings. Used about 10lbs last year. Product delivers results immediately.

Works Great on Rats!
I've been using this for years in Protecta bait stations around the house. Rats love it and I've never had a problem. We had quite a rat infestation around our bird feeders last summer, and I was able to wipe them out in about a week.

The product does not seem to work as well on Voles (field mice), however. The don't seem to be attracted to it very much. I am using JT Eaton Bait Blocks on them that contains peanut butter and other ingredients that attract them.
Review by Mr. Bob R. / (Posted on 4/13/2020)
Great product
The rats took out 10 of 20 blocks in the first week and a half. Rodent activity is starting to stop.
Review by Justin / (Posted on 4/5/2020)
Expensive, but worth every penny
I have used this in the past and am now about to place a new order. I can attest to its efficacy in killing rats! I can also attest to its snackability for dogs. While baiting areas with contrac blox, keep an eagle eye on your dog's poop. If you see that it's coming out a telltale teal color, go to the vet immediately and get vitamin K pills. This rodenticide prevents the body from normal production of that vitamin for the next 30 days or so, which means no ability for blood coagulation until vitamin k starts to be produced again. My dog was fine after a 30 day regimen of vitamin k. The rats . . . not so much. A pest control professional recommended this product to me.

Kills rats dead
Its not as fast as Final Blox, but its effective. Its fine to use if you dont mind it taking 4 days to work. If you need fast, you want final blox.

Otherwise I use it in bait stations around my property, save the final blox for something really bad.
Review by Jeff / (Posted on 1/27/2020)
Worth every penny
Excellent control of mice. We had an increasing amount of sighting and mouse droppings in the house. A pro was paid $200 for 15 minutes of work. He used this product. I ordered this myself since I decided to avoid his $50/ month maintenance fee.

The product worked immediately!

Contrac bloxs protect my valuables from rodents
Great blood thinner for rodents! It was in the basement that I found the 2 dead mice after putting it out. There’s 2 bait stations in the garage. 1 sets in the engine of my 429ci Ford Mach 1. Baited in the other 2 vehicle engines too. Big bait box with 4 Contrac bloxs behind the house at the 22Kw Generac. Also Contrac blox in a bait box in my gas shed. Great product that is protecting my valuables from rodents causing damage. Highly recommend.

This Stuff Works
Been using this in outside bait stations for years. Never been disappointed. With this season's reapplication, there was a noticeable drop in the rodent population. If you don't mind cleaning up the carcasses, this stuff is a relatively painless to use when properly applied.

It Works
Contrac Blox works at holding back the rat population near my house and workshop in a rural wooded area. Would recommend there use with the proper tamper resistant dispensers. I use four dispensers around my house and three around my shop.

I counted around 20 rats running around my chicken house! I spent money on products that didn’t work! When I put out the Contrac Bait Blocs every night. After 4 days I had dead rats everywhere. They were worth every penny!

Great stuff!
So I noticed some rat activity in my backyard while on vacation. I was so freaked out I called my mother in law and begged her to go to my house and put these pellets in my backyard. I had some just sitting in my backyard and some in stations.. i saw this rat run pass my camera 4 times with bait... saw a rat he next night... then got home from vacation and I have never seen one on my camera again which has motion detection and my bait stations have no been touched either.. now im stuck with a bucket but i dont care im prepared in case more come and have my stations left out and ill continue to update with fresh ones once a month.. i have a picture but it doesnt give me an option to post the rat running with it.

rodents not hungry?
Most of the rodents I deal with (ground squirrels, voles, mice) seem to be happy with contrac packets. They are turning up their noses at the blocks and the bait stations. It is late autumn and soon they may become hungrier but I was surprised at their refusal of the blocks over the bait packs.

Bought 6 ambush bait stations and the bucket of bait. Setup 4 so far with the bait. Very easy to assemble, and the price was excellent compared to the local service. Key was easy to use, and of course use gloves! Shipping was fast and package arrived in perfect condition.

Mice love it
So far the critters are eating it up. Ill come back for the second rating when I see them disappear Had to go to bait because the glue boards and the tin cats were not catching enough of them
Review by GJT / (Posted on 1/15/2018)
great product, i like contrac and final bloc equally as much... they worked amazing together!!!
i used contrac in conjuction with final blox.. some places they preferred one over the other but after a couple weeks, all activity stopped and i haven't heard or seen any signs of rodents!!! i am very pleased after spending lots of money on buckets from the feed store, That seemed to only semi work... i couldn't get ahead of them... this is well worth every penny!!! i am truly a satisfied customer...
Review by B.more / (Posted on 1/8/2018)
Awesome rodent bait
Great rodent bait. I get more activity with this bait than others that I have tried. Consider using a granular insecticide around your bait stations since slugs love this bait too.
Review by Toby / (Posted on 11/30/2017)
Haven’t found anything better
This works extremely well on mice. I have bought the standard offerings in Big Box stores and it’s just a waste of money. I learned of Contrac Blox by hiring a pest control service and then witnessing what they used. We generally have an influx of mice into our animal barn spaces in Oct each year (Indiana). I use this regularly by filling bait stations weekly, as the mice eat this stuff like candy. By the time we get to Dec, the mice have dwindled to near zero. I buy this in bulk and share with neighbors. It just works.

Great product
I have used this product for years in bait stations around the outside of my house and inside my barn which are located in a very rural area of Pennsylvania. The mice love it and it keeps the population at bay. I find much better results with the black square bait stations as opposed to the round white ones. I buy the 18lb pail so it lasts a while. Highly recommended.

Goodbye Rats and Mice!
This stuff works like a nightmare for the rodents! The boogers were making themselves to home in my home after the my neighbor's place was sold and cleaned up -- many derelict vehicles removed and garbage hauled off. Now just the birds are around like they use to be.
Review by Katie / (Posted on 6/27/2017)
Works amazing well and fast
Bought this bait along with bait boxes and snap traps. I added bait to the bait boxes and put the snap trap inside. Rats are unable to eat the bait with the snap trap in place. But that did not stop them from trying to get to the bait. 5 rats in 5 days found in snap traps. After a couple of days with no activity, I removed the snap traps. Two days later, all bait had been consumed. Refilled bait and two more days later, half the bait was gone. Since then, I found a couple of dead, rotting rats nearby. Another week, and no more sign of rats. Thank goodness.

I have used Contrac for years now as I live in the country. It doesn't just control them but it will wipe them out as my barn was overrun when I first started using it. Because I live near the woods every winter they come, both mice and rats. They eat and they die.
Review by Rob / (Posted on 2/12/2017)
I highly recommend!
I had a serious mouse infestation going on in my house. I took a chance and bought this product and it worked great. I now keep bait stations around the house as a preventative measure. I haven't seen any signs of a mouse in ages. I highly recommend Contrac blox. And costs much less than a professional, but works just as well.

Contract #1
Absolute best product for rat elimination.
Review by Chan / (Posted on 12/5/2016)
Does not work
I have 6 bait stations. In each station I place 4 Contrac blocks. In addition, I dump a tray of D-Con in front of the blocks. In each case the D-Con is gone but the Contrac blocks are barely nibbled. I think this was a waste of money.

********DIY Response********

In order to make the block forms of bait like Contrac weather-resistant, the food is covered in wax. This reduces the smell slightly so other forms of bait placed next to it may be eaten first. Contrac is highly accepted by rats and mice. We sell to many farms and pest control firms and Contrac Blox is their preferred bait by a substantial margin.

Always good service and price
I have used this bait for some time. Good service and competitive price.
Review by Chk3 / (Posted on 10/18/2016)
did not work
Mice won't touch it. I have tried putting peanut butter, honey and apple juice on it- nothing. Squirrels love it though. I was told by the salesperson the minimum amount that can be sold is 18 pounds. This is not true. I found it in 4 pounds packages on Jet.com, Solutions Pest & lawn and eBay. if you want to try it, I strongly suggest trying the 4 pounds first as I now have an 18-pound toxic paperweight.

********DIY Response********

I'm sorry you are having issues with mice accepting the bait. It is very unusual. Contrac is usually the rodent's favorite in comparison tests. As for the packaging, Contrac Blox are still packaged in four-pound pails, but legally they can only sold in boxes of four, Sixteen pounds is the smallest quantity in which any second generation anticoagulant rodent bait can be sold. Please contact us 800-476-3368 and we can offer some solutions and see to it that you get rid of your rodents.

Never fails
Great product. Well worth the cost. Never fails to rid the premises of rats within days. Works well in the protecta lp bait station. I have dogs and although extremely careful, i needed a bait that has a readily available antidote in case of accidental ingestion. This fits the bill. I miss the smaller pail size but will continue to purchase as it works so well.
Review by S / (Posted on 6/7/2016)
Works Well
We had an explosion of mice this last year, since there wasn't a lot of snow. Contrac Blox has worked the best so far. Very effective. I used the Protecta Mouse Bait Stations as well, they are holding up well.

Kills rats, safer for Dogs
This product is fantastic. I had a pest control company come out and set a bait station for $140, it worked okay until the blocs were gone, about a week. The rats were still in my roof so I got this product for the price of one pro visit. I'm tossing out 5-6 dead rats a week.
Review by Lunchbox / (Posted on 4/2/2016)
It works!
This product is highly effective for eliminating rat and mouse populations and is what many "professionals" use for critter control. We use in tandem with Protecta Sidekick bait stations (a must to protect pets, birds and larger wild animals) with great success. Highly recommended.

Works for rat Infestations
This is a very good product that works if you follow the instructions and keep the boxes full. I live on a remote island where there will forever be a large population of Norway rats, I have six boxes that I keep full around my property, and they do an excellent job of keeping my property clear of the rats. During the colder months I need to refill the boxes every month, and during the summer, it's less often. The rats go home to die when they get an upset tummy after digesting, and so you will not find the dead rats around. In the 8 years I have been using this product successfully, I have only ever seen three dead rats. Just to put the effectiveness in perspective; before finding this product, I was using hav-a-harts and rat snap-traps to catch about a dozen rats a week. Now I do not even see them. The bait works. NOTE: If you have a current infestation, it takes up to three weeks for the infestation to end, so BE PATIENT as you kill off a larger family. Also, this product is in locked boxes and safe for other pets - even rabbits (small but not rodents and can't get into the boxes). I highly recommend to anyone dealing with a rat infestation.

Bait with Stations work like a charm
Had significant activity in my yard, attic, and walls. This bait, with the bait stations, worked awesome and as advertised. Found one dead mouse in a bait station, and it appeared that the anticoagulant worked as advertised (without getting into too much gory detail).

I would buy this again, but might not have to, as a bucket is going a long way!

Will not buy again
I would not buy Lumitrak again. Thought it would be interesting to get this bait that leaves a trail. But it appears not to be as effective as the regular Contrac Blox,
Review by CrewCab Daddy / (Posted on 12/20/2014)
The bait arrived at the farm and we put the bait out on a wire within a cage and they were eating on it pretty steady for the last 3 weeks and now it seems like it has slowed down. Hopefully this will get rid of the mice and rats eating the wiring within the farm machinery and cars parked in the pole bar. This facility stores large combines and tractors and old antiques so we want the equipment safe from the destruction of mice and rats. I have used other pest control products from this company and they really work excellent.

Great stuff - couldn't be happierd
I am on my third bucket of blox and I couldn't be happier. I use them in our barn in a large bait station and the mice have not gotten in our motorhome or boat in years. I keep the large bait traps around for the pack rats and the small traps in the motorhome for any mice that may make their way in for a warm place to sleep. I used to buy decon but I couldn't keep up. They would pack it away and I still had mice. . The blocks make it so they have to eat it a little at a time and a little bit kills them quick. I do recommend the blocks regularly to anyone I hear has a rodent problem. The bait traps and bait are the same traps the pest control company set at a friends house and charge her $45.00 a month to come check and reload! Works on chipmunks too. Pretty much any destructive rodent.

Excellent product
This is a killer product... kills mice and rats in no time flat. I use it in the basement and in a garage that borders a field where the mice like to hang out and come in the garage to hibernate in the winter - they hibernate all right DEAD..

Contrac Blox
I've been using it in the back yard for eight years with the feeding stations. Have not seen alive rodent since. Having pets in the home the feeding stations are a great way of protecting them from the Contrac Blox.

Did the trick!
Eating thru the wires of our HVAC system (under the house; in a rural area). Between a better sealing of the house & this bait, situation is finally under control!

The BEST on the market
We bought this for my sister living in Fla. She lives on the canal there in Hallandale. The RATS were so bad they ate through the floors the roof & the walls at night. At times she would wake up & the rats would be starring at her....
We sent her 18 bricks. She could not believe it there were so many dead rats because after they would eat this I guess it made them thirsty when she would go by the canal there were so many rats she called the city health Dept...
Now she replaced the floors the roof she does not live without this product it's the BEST ON THE MARKET.....

Great Rat Killer
I have been using Contrac Blox for years and didn't know it. My overpriced pest control company was soaking me! I found this site and ordered and have saved myself a lot of money by doing so.

This stuff works. After you get this instead of the regular color rat droppings you will see just a few droppings that look exactly like the block. When you see that put your mind at ease. Dead Rat Walking!

It works trust me!

Excellent Rodent Stopper
Once I place the bait blocks where they need to be, the noise stops within a week.
