Highly effective rodent control - fast-acting professional results!
Tomcat Bromethalin Bait Chunx are incredibly effective for rodent control and have solved my pest problem completely! Living in a rural area with barns and outbuildings, rodent control is essential for protecting stored feed and equipment. These bait blocks work exceptionally well - I noticed results within days of placement. The bromethalin formula is highly effective and provides faster results than traditional anticoagulant baits. The chunx format is perfect - the blocks are large enough that rodents can't carry them away, and they're weather-resistant for outdoor use in bait stations. I love that they're specifically designed for agricultural use, making them ideal for barns, sheds, and farm buildings. The 4-pound bucket provides excellent value with plenty of blocks for multiple bait stations. The blocks maintain their integrity even in humid conditions. They're easy to handle and place in bait stations. The effectiveness is outstanding - my rodent population has been eliminated. I appreciate the quick-acting formula that provides humane control. The blocks are palatable to rodents and consistently consumed. Perfect for farmers, homeowners with outbuildings, or anyone dealing with serious rodent issues. The resealable bucket keeps unused blocks fresh. Essential for protecting property, equipment, and stored goods from rodent damage. The professional-grade formula delivers reliable results. Great value for the amount you receive. Highly effective pest control solution that actually works!

this works!... with some rat intel...
we HAD an outdoor rat infestation, but are now living rat-free!!! ... thanks to this bait and the other measures below! just as claimed, this MOTOMCO rat bait with Bromethalin really works! ... the rats ate this bait and returned to the nests to perish. the following is some things we learned from our lil' rat skirmish; | rat intel | • neighborhood activism: get your neighbors involved, as the problem is very unlikely limited to your property... rats eat dog feces and bird seed and just about anything, but, in our neighborhood, it is the theory that they were feeding (or are still feeding) at a neighbor that does not clean up after their dog and living at another neighbor that does not leave their home interior and has let their garage and yard go to squaller…. thus, our yard has become a traffic route and/or playground between these two locations on our street. but it is a city wide problem, as we have learned via nextdoor website for our city… so, neighbor involvement is a must, as you may eliminate them from living, playing, or feeding on your property, but they will still be local and will likely return. if you do not know your neighbors and do not want to do the door-to-door thing, then join nextdoordotcom for your city and post something like "Unwanted Neighbors - Rats!" ... this is how we learned that it is a pervasive, city-wide problem and we are both receiving and disseminating information via this site… though i appreciate that most of us no longer “need” neighbors in this era, you do NEED your neighbors as allies in this war! • multi-front approach: utilize some additional artillery besides bait in bait boxes, such as Victor traps... the Victor traps are tried and true traps, and the most efficient and cost effective means of eliminating rats... they are easy to set & hold with great sensitivity... and, they work! • bait type matters!: as far as bait for bait boxes, Bromethalin is in these bait chunks and is the ingredient claimed to be the best to poison rats. as for trap bait, we first tried peanut butter with no results on the rats, but it resulted in some very unfortunate collateral damage to other rodents... so, we switched to raw bacon, and, while the other rodents are disinterested, the rats can not resist, and snap!, our rat squatter war is slowly being won! so, if it is outdoors, do not use peanut butter, unless you want to eliminate chipmunks and squirrels, as well (we do not) ... rather, try raw bacon... • fresh bait: we found our best success with traps was to keep them fresh... we changed the bait and reset the traps almost daily, then really began having success! ☐ here are links to some good outdoor rat bait boxes and a good value 12-pack of Victor traps: • Compact Rat Bait Station TWIN PACK (Bait Not Included) • Tomcat 0370910 Tier 1 Refillable Rat & Mouse Bait Station and, traps for the additional front: • Victor Metal Pedal Rat Trap (Pack of 12) lastly, if you want to keep it cheap and simple, then the Victor traps can not be beat, especially in the economical 12 pack. best wishes to your soon rat-free life… :-) Thank you.

Flat out AMAZING! This worked EXACTLY as it said it would and on only 1 feeding
Wow, so we had a rain storm here in Florida, during a massive community wide garage sale. Our garage doors were open and we saw this giant, I mean large rat run in from our mulch bed to our garage. Everyone panicked lol. It was like a scary movie. First night I tried some good mousetraps (20 bucks for 6 of them, they were legit ones with claws on the snapper etc, but the rat was able to get the peanut butter and set off the traps but they weren't going to get him. So I ordered two tomcat boxes as well as a pail of the tomcat feeding pods (the 4lb pail of green pods). I placed two of these black boxes which are pet safe for dogs and cats, along the walls of the inside of my garage. The morning after I placed them, I opened the first box and sure enough, two of the tomcat pods had been chewed on. That was Tuesday night they were placed. Wednesday morning I checked the box and saw it nibbled on. I told my wife on Wednesday night that we should expect anytime from Thursday to Sunday, this rat to be dead. I said 1 of 2 things is going to happen, this rat I saw twice, run up to a ceiling rack in my garage as I heard traps going off late at night and I ran over to the garage to check out if they got it. Well, I said it's 1. Going to fall out of one of the racks once this poison takes over. Or 2. It would die in the rack, or perhaps it's on the shelving or somewhere else in the garage at the time it hits it. You never know where those things are because they hide. It's Thursday morning, I hear this scream and I didn't know if my wife was being attacked but within two seconds I realized she was going out to work. The rat had dropped out of the ceiling rack and slid off her SUV as she backed out. Not kidding. I said to her this was best case because we didn't have to be spooked taking things off our ceiling racks and all our shelving searching for a dead rat. I kid you not. It was sitting on our driveway and I scooped it up in to a small box and disposed everything in a sanitary way. So pleased with this stuff. First night, it lured the rat. It says it works off one feeding and after 1-4 days of the feeding. We experienced this all just as it said it would happen. I could not be happier. Two tomcat black boxes and one bucket of this stuff was just over fifty bucks. The cost for an exterminator would have been far more, I have enough of this now for a long time. I am so happy we went after it before it got inside the house by eating through the drywall of the garage and did major damage to wiring etc. It actually in just the first night, had eaten off and shredded the weather sealing on about 6" worth of it, on our door in our garage that leads to the house. Shredded it. It was a panic in the home for a few nights here but this was the perfect remedy and it's addressed. GREAT product!!!!! Follow the directions, couldn't have been easier. In 2 minutes I had the box and poison pods on the rods, all done. It worked EXACTLY as it said it would.

THIS PRODUCT SEEMS TO WORK WELL- I CONSIDER IT HAZARDOUS MATERIAL
This product is a pretty good product. The review asked me how many stars to give it for Flavor. I guess they think that the customer is going to taste it by putting it in his mouth. I had trouble this past couple of years with mice coming into my mobile home. Its skirted and I ordered this to put under the moble home. I put about 3 lbs inside the skirting and have not seen a single mouse or rat. I live next to a treeline and i sometimes feel i could put this bait along that treeline but i have dogs and dont want to let them get ahold of it. They do have plastic containers where one can place this inside them. I dont think they are well designed enough to allow the mice to go inside to taste this stuff. 4 lbs is a pretty big container. I cant imagine someone useing the whole container at once. I would definately not use it if there are children around. I worry what this stuff is made of and what would happen if a dog or child would taste it or injest it. I didnt really see that many warnings on the container. There are other products that are more child friendly. I dont want to find out what happens when a kid eats this. The container itself is easy to open and i dont like that. And the appearance of the product looks like it could be tempting to a child. I think improvments could/need to be made in both the warnings and the container its sold in.

Its Control, Not Total Elimination.
Okay, I see one star to 5 stars. I am not a company spokesman but I can tell you few thing about rats. Number one they are smart, much smarter than you think. I live in the city with restaurants not far from my home and surrounded by neighbors with dogs and cats, rats love to eat their food too. The best poisons are long gone; the government forced them off the market. This is the same bait used by pest control companies. The EPA ban all other poisons several years ago. What you should know is rats are territorial, Once you have killed out one colony another will soon move in if there is a food source. The best method of removing rats is to get rid of their food source. If that is not possible then you need to poison them. Traps don't work. Why? When one rat is caught the other will avoid the traps. Also, you need to make sure it is rats or mice that are eating your bait. My bait was disappearing every night. I set up my game camera only to find possums and raccoons raiding my bait stations. I had to come up with something different. I used a 4 foot long 3.5 inch PVC pipe, blocked off the end to a point that a raccoon or possum could not get into my station. I secured the pipe so that it could not move. I only bait at night. Generally, rats are nautical, they move and feed at night. After I set this station up I started to find dead rats. The one thing about using this poison is that the rats don't usually avoid it but they wander off and die. The other rats are not suspicious of the bait. Mice and rats can reproduce every 90 days and have 8 litters every year. The mice/rat gestational period is only 21 days. You'll never ever get rid of them completely. The trick is to control the population. There is no one who hates rats more than me. I have learned how to keep them under control, but we'll never get 100% rid of them. The best way to control is to eliminate their food source and your neighbors should be doing the same. UPDATE: after only three days the rodent damage stopped, I am not seeing rodents on my camera. I will continue to keep the bait out but this has worked 100%. As long as your neighbors keep feeding their pets outside rodent will keep coming. Control the problem. Your neighbors are not going to change their ways, but you can keep the rodent at bay by baiting them.

WORKS !!
Edit : PSA for users. Please use the bait box. This one kills squirrels... It broke my heart to wake up one morning to see a dead squirrel. I buried the little one in my yard. I thought tossing these throughout would do the job. And it did, as you can read about in my original review below. But this also kills animals that you'd not want to harm. As soon as I found the squirrel, I went on amazon and bought 3 bait boxes. And now all my baits are placed inside the boxes, so that only rats and mice can enter. Please be mindful of this fact, if you care about wildlife at all. I feel absolutely horrible. Original review : Heard noises in the attic, critters running around scratching. VERY stress inducing, in the middle of the night. I just had no idea WHAT I was dealing with, because I never could see them. Mice? Rats? Squirrels? But I did find droppings, so I showed it to a rodent control guy, and he said "Those are rats". Anyways, I went up on the roof and sealed off every entry I could find, and then placed these Tomcat baits around the house OUTSIDE. The rodent control guy told me I ran the risk of TRAPPING a live rat inside the attic because I sealed off the holes without knowing they were out. I had no idea. But I just had a feeling they were out during the day because I coulnd't hear them at all. But he also told me that's because they are nocturnal, not necessarily that they actually LEFT the attic. Anyways, what's done was done and it was water under the bridge at that point, because I sealed off the entry points BEFORE I called the rodent control guy. Anyways, I went ahead and placed 4 of these blocks around the house, and next day, they were all gone !!! And the subsequent days, I didn't hear ANYTHING in the attic either. 4 days later, while I was out doing yard work, I saw the dead corpses of 2 rats !!!!!! I was disgusted. I'm a city boy, and I NEVER saw a rat in real life !!! Took my shovel, and tossed them in the trash bin. Anyways, been about 4~5 days since I used this product, and haven't heard rats in the attic since. Not to mention the dead rats. I'm gonna get in the habit of placing these around the house on a regular basis so that they never get near the house. I'm amazed these work so well.

It works if you can ever get anything to eat it, but it's a cruel way to die
We live in the woods and living with nature is just part of the deal. Things had been fine forever, but something changed in the last few years and rodents seemed to overpopulate and take over and become very aggressive. Mice, chipmunks, and squirrels started breaking into the attic and crawlspace causing thousands of dollars of damage to the insulation and to the heating and air conditioning ducts. Mice in the house were eating food and clothing and destroying lots of other stuff. Voles were eating plants in the garden and mice in the garage were eating and destroying things. Chipmunks had caused broken sidewalks and driveways with their tunnels undermining them and they had even tunneled under the foundation footing to come inside the crawlspace and chewed into many of the HVAC ducts. There were nuts and acorns in the ducts and all over the crawlspace. I really don't want to kill things so I tried all of the humane ways I could find to exclude and repel them but nothing worked. Finally when I discovered a rodent nest inside one of the heating ducts and realized that we were obviously breathing their hair and feces as it blew the air into the house, I decided enough was enough and it was time to take serious action. I stuck with mouse traps in the house because we didn't want poisoned ones dying in the walls or house. Outside and in the garage I tried this product. First I tried using rat traps to catch the squirrels, but didn’t catch a single one in a few weeks, so then I figured maybe I had to go with poison even though I thought it must be a terrible way to die. I researched the different poisons and thought that the common anti-coagulants seemed the worst—dying from internal bleeding. Finally I settled on Bromethalin thinking it might be the “least bad” of them all. And that’s how I ended up choosing these Tomcat Bait Chunx. First, yes I know this product is not labeled for squirrels and chipmunks but they are rodents and I know it will kill them too. Day 1 I put a few full chunks on the trees and within a few hours 3 were gone so I figured we were in business. I continued to put out chunks and parts of chunks but fewer and fewer were being taken and I continued to have lots of squirrel problems. It was early spring so I thought maybe they were storing them in their nests and not actually eating them. I put some chunks near the vole holes and they all disappeared and after a couple of weeks it seemed all of the voles were gone. Success. In the garage, I never saw so much as a nibble on any of the tomcat chunks so obviously the mice don't like them. Fail. I went back to mousetraps baited with peanut butter and continued to catch mice and one shrew. After about a week I started seeing fewer squirrels so the poison seemed to be working. Hopefully success… Then one day I went outside and a tiny baby squirrel ran straight up to me and started climbing up my leg. In all of years of living out here I'd never seen a squirrel approach a human, much less run up his leg! It was obviously scared and alone. I knew that the poison must have killed its parents because you never see a squirrel that small. It must have come out of its nest because it was starving. You could see the look of fear in its eyes and a "help me" kind of attitude. So here I was on one hand trying to kill them but on the other hand here's a scared baby begging for help. It kept climbing up my pant leg and sat in my (gloved) hand and tried to keep climbing up to my head. I sat it down and got it some nuts and water and it gobbled them up for a good 30 minutes and then tried to run up a tree but it wasn't strong enough so it ran off into the woods. The next day I found its back legs and tail. Something had eaten the rest of it. I thought to myself...this is the circle of life...someone dies and someone is fed. It's nature. But by then the squirrels stopped eating the tomcat chunks. Who knows if they lost their taste for them or if they figured out they were poison. So I started cutting up the chunks and mixing them with peanut butter and squirrels started eating them again. Over the next few days I saw a few more baby squirrels in the same orphaned situation so I gave them food and water also. Then one day I watched a baby squirrel try to run and then it fell over. It would run a few feet and fall over. Run a few feet and fall over. I knew that the active ingredient Bromethalin works on the nervous system, eventually causing paralysis and then death and here I was seeing it in action. I felt bad to watch this baby squirrel suffer and so I decided I had to find a more humane way that would lead to as instant a death as possible. I looked into ones that shock them, smash them in the head, and every other method I could find. Finally I settled on the old-fashioned conibear 110 traps baited with peanut butter and have mainly stuck with that method ever since. It’s mostly an instant kill but sadly, not always. I still use these Tomcat chunx mixed with peanut butter for the squirrels and chipmunks that continue to be a problem and simply won’t get trapped. Total kill has been 24 squirrels by conibear trap and an estimated 5-7 by Tomcat chunx, so you can see that the traps are much more effective and also more humane. I also caught 2 chipmunks with the conibears and probably a few more with the peanut butter poison. Again, I feel bad for having to go to this extreme to protect us and our home, but it seems like it has to be done because they just keep coming and trying to break in. As I was anguishing over killing things, a buddy of mine told me “Look, we’ve killed all the predators so things are out of balance and there’s nothing to kill the rodents. YOU have to be the predator.” And so, with that frame of mind I was able to do it and protect the health and safety of our family. Still I’m not happy about it. I take it seriously that I’m taking a life and anybody who uses this stuff should too. From what I’ve seen, poisoning is a cruel way to die and so I use it only as a last resort. I think the traps are a much more effective and humane way to go. As an aside, if I ever do have to buy rodent poison again I probably wouldn’t buy this product since the mice, chipmunks, and squirrels don’t seem to like it. There’s a peanut butter flavored bait by another company that I’d probably try next time.
