Best Tomcat Rat Poisons | Chunks & Pellets. 2022 Buyer’s Guide

What is the best Tomcat rat poison? Depending on the situation, you may choose fast-acting and highly toxic bromethalin or slow-acting diphacinone that kills only when multiple doses are consumed. Tomcat baits are formulated as chunks or pellets. The former ones are designed for a bait station and have a hole inside. Pellets are more versatile and suitable for mixing with all kinds of food items. There is also a bait product designed to withstand adverse weather conditions.

Why Tomcat?

This is a well-known brand on the rodent control market that offers a variety of high-quality and efficient products. Tomcat baits are fresh tasting and very appealing to rats and mice. Manufactured using an advanced formulation process, they attract rodents, including those resistant to other poisons. They boast a long shelf life and an enticing flavor. There is also a line of weather-resistant baits that preserve their effectiveness under any weather conditions when applied outdoors.

Types of Tomcat Rodent Baits

Tomcat baits are available in large pails, with a volume ranging from 4 to 10 pounds. This is an economical option for everyday rodent control, allowing you to efficiently apply rat poison to both small and large areas as well as to hard-to-reach areas.

Made in the form of chunks or pellets, they satisfy different customer needs. The advantage of chunks is that they have a hole inside and can be easily placed on the rod in a bait station or pinned to any surface. Pellets are smaller in size and more versatile. You can easily mix the pellets with rats’ favorite food to make the bait more attractive to them.

Some Tomcat rat poisons come placed inside of a bait station to prevent any potential harm to children and pets. There are both refillable and disposable bait stations, with the latter being cheaper (under $10). In our assessment, it is more cost-efficient to buy reusable bait stations, however, much depends on the level of infestation. In addition to baits, Tomcat offers rodent traps and repellents for rodents, ensuring an integrated approach to pest control management.

More importantly, Tomcat rat poisons differ by the active ingredient used. They are based on either bromethalin or diphacinone. These are not just different chemical compounds — bromethalin or diphacinone have a different mode of action. Bromethalin is an acute toxin that kills rodents by disrupting their nervous system. It is a fast-acting poison, so a single dose is sufficient for a rat to die. The downside of this ingredient is the absence of an antidote, which is why it is considered to be very dangerous to use around pets and livestock.

Diphacinone is a slow-acting poison that requires multiple feedings to kill a rat or mouse. Due to the delayed effect, it is often preferred for application in residential areas where small children or pets run a risk of accidental poisoning. It kills rodents by causing internal bleeding.

The Effectiveness of Tomcat Baits Based on Scientific Evidence

The Tomcat brand is not just popular with customers, but it is also referred to in scientific studies on rodent control products. Scientists from the University of Nebraska-Lincoln mention this brand, along with D-Con and JT Eaton, as a manufacturer of both slow-acting and fast-acting rodent poisons.

They note that bromethalin-based products are more toxic and should be preferred in areas where rodents are abundant. Since such poisons kill after a single dose is consumed, they are recommended for situations where there are other alternative food sources that cannot be removed. In this case, it may be hard to get rodents to consume the bait several times in succession. The advantage of using baits containing diphacinone is that they are much safer and will not lead to bait shyness.

Researchers at Purdue University highlight the importance of using bait stations, which can be non-tamper-proof or tamper-proof like the Redtop Bait Station. This container comes with two security keys and bait security rods. It can be mounted to the wall both vertically and horizontally and is equipped with a removable bucket that makes cleaning easier.

According to the experts, there are three reasons for placing baits in containers rather than broadcasting them around the ground.

  1. Bait stations decrease the chance of accidental poisoning of pets and livestock.
  2. They allow you to easily monitor whether and how often rats eat the poison. But keep in mind that rodents may store bait to eat it later.
  3. Boxes preserve the freshness of baits, protecting them from dust, manure, rain, and snow. Contrary to popular belief, rodents tend to avoid dirty or contaminated food.

Best Tomcat Rat Poison Reviews

Below, you will find a review of the best Tomcat rat poisons at a price ranging from $15 to $46. There are more toxic baits that can be used in and around agricultural facilities only and multi-dose poisons that can be applied in residential areas as well. Some poisons are formulated as chunks and are ideal for use in a bait station while others come in the form of pellets and are particularly efficient when a large area needs to be covered.

Tomcat Bait Chunx Pail 4 LB | Best Overall

Tomcat Bait Chunx Pail 4 LB: photo

This is the most popular product from the Tomcat brand and here is why. The Tomcat Bait Chunx is both efficient and safe for use. It should be used only with a bait station because its active ingredient, bromethalin, is a potent toxicant. Moreover, you can use it only in rural and agricultural settings. The reason for using bromethalin-based baits is that they are good at controlling severe rat infestations.

The product effectively eliminates both roof and Norway rats as well as mice. Once they consume a lethal dose, they stop feeding and starve to death. The first deaths will occur in two days and more, so this product will not cause bait shyness in rats. The bait chunks are made with multiple edges that are appealing to rats, stimulating them to gnaw. They are resistant to mold and moisture, so feel free to place it outdoors. On top of that, these bait chunks are highly palatable as they include food-grade ingredients and are low in paraffin.

Customers recommend this product and one of them notes that since rats are territorial, it is useless to kill just one colony because another one will move in soon. The only way to keep them away, he says, is poisoning. The Tomcat bait did a great job and “was disappearing every night.”

Tomcat All Weather Bait Chunx, 4 Lb | Best for Humid Environments

Tomcat All Weather Bait Chunx, 4 Lb: photo

If you live in a region with unfavorable weather conditions, this product will solve your problem seamlessly. It can be used in a variety of baiting situations and remains effective in moist environments. Another advantage of this option is palatability. The poison chunks are flavored with peanut butter, which is the rats’ favorite. Like the previous product, this one also contains food-grade ingredients and just an insignificant amount of paraffin. The bait block features the unique shape and edges that are preferred by rats.

The baits are made with diphacinone, a multiple-feed poison that acts as a blood thinner. Since a single dose is not lethal, it is considered to be safer than bromethalin to use around target animals and small children. Customers rate it highly and say that it is an excellent outside weather bait product. One of the buyers highlights that the chunks stay good in the bait station as long as the lid is on tight. They are not washed away by rains and do not grow moldy.

Motomco 008-32345 Tomcat Rat and Mouse Bait Pellet, 10 lb | Best for Large Areas

Motomco 008-32345 Tomcat Rat and Mouse Bait Pellet: photo

If you need to get rid of rats in a large area, choose this product. For less than $50, you get a 10-pound pail of rat poison. Not only is it cost-efficient but it is also convenient to use in and around agricultural structures. The bait comes in the form of small pellets that can be mixed with corn, nuts, or any other food preferred by rodents. This will help to avoid bait shyness and encourage rats to eat the poison. Once a rat consumes the bait, it will take at least 4 days for the rodent to die, meaning other rats will not associate their buddy’s sickness with your poison.

That said, the product is made with diphacinone, a poison that requires several feedings to kill. This makes the pellets a safer option to use around livestock in farms. Besides, they are resistant to mold and moisture, so you can safely place them through the barnyard in any weather. But make sure that neither livestock nor pets and children have access to the poison.

Customers gave 5 stars to the Tomcat Rat Pellets and seem to be satisfied with the purchase. One of the buyers describes the poison as “incredible” and recommends placing it around the interior of an infested shed or other such facilities.

Tomcat Rat & Mouse Killer Refillable Bait Station | Best Pre-Baited Station

Tomcat Rat & Mouse Killer Refillable Bait Station: photo

What separates this Tomcat product from others on the list is that it is a pre-baited station. No need for touching dangerous substances, just place the box where rats travel — somewhere within 20 to 100 feet between their nests and the source of food. More importantly, neither kids nor dogs will be able to open the bait station because it is tamper-resistant. However, the product is reusable, meaning it needs to be refilled with bait if you are going to continue to use it after rodents eat all that is inside.

The pack includes one station with 15 bait blocks, with each block killing up to 3 rats. Since the box can hold up to 2 blocks simultaneously, you can refill it up to eight times. The bait is made with bromethalin, a highly poisonous neurotoxin. The baits station is weather-resistant and can be safely placed outdoors. It is made with a transparent window allowing you to easily check whether there is enough bait in the box.

The Tomcat Rat & Mouse Killer has received 4 out of 5 stars in customer reviews. Buyers draw attention to the fact that it is made with a dangerous poison that has no antidote, so it is important to handle it very carefully. But this bait station is worth using as it really helps eliminate a rat problem. Besides, it is easy to use. Just load bait chunks and monitor them through the built-in window without opening the box.

Tomcat vs Neogen: Pros&Cons

Neogen Ramik Green Fish Flavored Rodenticide Nuggets: photo

If you are looking for a cheaper alternative, try the Neogen Ramik Green Fish Flavored Rodenticide Nuggets. Founded in 1982 in Michigan, today, Neogen is a trusted American company that offers solutions for food and animal safety. It makes rodent control products with different active ingredients including diphacinone, bromethalin, and zinc phosphide. The baits are available in the form of blocks, pellets, place packs, meal bait, and nuggets.

This poison is formulated as nuggets that look like natural food. Made with .005% diphacinone, it kills rodents slowly but surely. However, the product does not seem to be very palatable to rats. While it is flavored with fish and contains a mix of grains — something that is supposed to attract rodents — rats do not rush to eat it immediately.

One of the buyers says that initially, he thought that the stuff did not work because the bait disappeared but rats were still there. But after a while, they all were gone. As it turns out, rats had been storing the bait nuggets and only recently ate it. This means the product does work but it is not something that rats cannot resist eating.

Neogen Rat Poison


  • A very good value. It is much cheaper than Tomcat ($17 against $30 for a 4-pound pack of poison)
  • Weather-resistant and is suitable for outdoor use
  • Made without the use of wax
  • The bag is resealable


  • Rats may not eat the bait immediately because it does not seem to be highly palatable.
  • May not work on the second try

Tomcat Rat Poison


  • A higher quality of ingredients
  • The Tomcat bait is very palatable both to rats and mice.
  • Made with only a small amount of wax
  • Weather-resistant. There is also an option developed specifically for use in bad weather conditions.
  • Does not cause baits shyness


  • Tomcat baits are more expensive

What Buyers Say: Customer Reviews

In this review, a blogger says that he had rats in the attic. They were climbing through the walls and getting into the kitchen. And then, he purchased the Tomcat rat & mouse killer. It looks like a mousetrap, which prevents dogs and cats from grabbing and eating the toxic bait. He put this thing in the attic and it really works! Since that time, he has not had a rat problem for months.

This blogger has reviewed the Tomcat mouse killer, which is supposed to catch up to 12 mice. It has hardcore chemicals in there, so you really need to be careful with this stuff. He notes that it is guaranteed that if it does not catch mice, you can send your receipt and they will send your money back. The bait station should be placed at the highest point along the wall, 8 to 12 feet apart. Mice eat the bait, walk away, and die.
