PROS

With poison blocks incorporating multiple edges, the rodents will usually feel inclined to gnaw them away. Each block can kill ~12 rodents. Aside from moisture, these poison chunks are also mold-resistant, so you can use them outdoors as well as indoors. 

CONS

Though the product is moisture-resistant, it is not quite waterproof. 

OUR VERDICT

Motomco Tomcat Bait Chunx Pail shrinks the highest rodent populations and can eliminate the more severe infestations. More often than not, the rodents that consume this poison do not live to see the second day. Food-grade ingredients make the poison blocks palatable.

PROS

The nuggets can be used in wet and damp areas. Made without wax, these hot-extruded nuggets are resistant to the elements. The product is available in a 4-pound bag as well as a 20-pound bucket, with the second option enabling safe storage and transportation. 

CONS

You have to store the poison in a metal tin with a lid as the plastic bags these nuggets are shipped with can easily be eaten through by mice.

OUR VERDICT

Neogen Ramik Green Rodenticide Nuggets is the tastiest poison we've reviewed yet. Incorporating food processing and fish additives, the nuggets retain freshness and sweetness but also prove as effective as non-palatable mice and rat killers.

PROS

Even though the bait station is quite compact, its construction is tamper-resistant, so the more inquisitive children and pets will not be able to open the trap and come in contact with the poison. Nevertheless, made from 99% food-grade ingredients, this poison is harmless to them.

CONS

The bait chunks are soft and easily breakable.

OUR VERDICT

D-con Cholecalciferol Mouse Poison Bait Station ships you everything you need to start exterminating: some poison and a trap that holds the poison, making sure that kids and pets are safe around it but the rodents can still easily access the bait.

Irresistible to Rodents

Farnam Bromadiolone Just One Bite II Bait eliminates house mice, roof rats, and even warfarin-resistant Norway rats. The poison can also kill meadow voles but California rules do not allow killing these species, so do with it what you will. Both Norway rats and house mice types might consume a lethal dose in short as a single night's feeding, with bromadiolone, a second-generation anticoagulant, causing internal bleeding and neutralizing these pests.

The palatable formula incorporates grains and seeds, making the product an excellent attractant that rodents cannot normally resist. Also, featuring nibble ridges, these bait chunks help rodents chew the bait and distribute the poison.

But, because the formula is as effective as it is, the poison can easily harm pets, so the people behind it recommend placing these bait chunks only in and around agricultural buildings. Placing them will seldom prove an issue though, owing to the center mounting holes that the baits come equipped with, enabling easy application in bait stations.

Bottom line, Farnam Bromadiolone Just One Bite II Bait will let you show rodents that they're not welcome. With this poison, you can solve even the most severe rodent problem.

Eliminating the Smallest Rodents

JT Eaton 166004 709-PN Bait Block is an anticoagulant block bait. Using specially formulated peanut butter flavor, the bait is able to attract and neutralize rodents. With diphacinone (0.005%) serving as the primary active ingredient, this product can also eliminate the smallest rodents.

But the best part here has to be the 144 one-ounce rodenticide blocks that the bucket's filled with. Coming inside a tamper-evident resealable pail, these blocks will let you exterminate rodents from basements, garages, and more. Generally speaking, you can easily transport the bucket, which is great except that the blocks are not packed especially firmly, so they can make a huge waste when you're not careful with them.

The bright side is the aforementioned pail, letting you not just carry and transport the poison with relative ease but also store the bait blocks without buying or using separate storage containers. More often than not, the formula will start producing visible results within 2-3 days, killing most rodents on the second day.

In other words, JT Eaton 166004 709-PN Bait Block will accommodate commercial and residential spaces alike. Killing rats and naming names, this poison will let you establish and maintain a rodent-free environment.

Handling Severe Infestations

Motomco Tomcat Bait Chunx Pail employs 0.01% Bromethalin, making this product effective at shrinking high rodent populations as well as eliminating severe infestations. Because the ingredient is an acute, non-anticoagulant active element, rodents usually die within 2 days of consuming this poison.

Of course, first, you have to attract these rodents, which is where the chunks' shape comes into play. Featuring multiple edges, the chunks appeal to rodents' gnawing instinct, so they can seldom resist the poison. Plus, these blocks incorporate food-grade ingredients and small paraffin amounts, making the bait more than palatable.

For the most part, this is one tough product, with the blocks being both mold- and moisture-resistant. However, they're not quite waterproof, so while you can use the bait outdoors, make sure that the forecast is not promising anything but sunshine and rainbows.

As long as you do that, these chunks, killing ~12 rodents each, will let you save even sizable agricultural premises from severe infestations. To add more, each block integrates multiple holes, so you can place them on bait station rods or secure the chunks with nails and/or wire, making sure that the chunks do not go anywhere before rodents can consume them.

Go with the Nuggets

Neogen Ramik Green Rodenticide Nuggets is a tricky one. While most mice and rat poisons are seldom palatable, this one is downright tasty. Relying upon effective food processing tech and fish-based flavorants, this product can retain its freshness and sweetness without becoming less effective. What's more, the nugget form makes the poison as well as the taste long-lasting.

In fact, rodents might find them too tasty, so we would recommend storing these nuggets in some metal tin with a tight lid since rodents can easily eat through the plastic bag that the nuggets are shipped inside. On the upside, because the nuggets are hot-extruded and made without adding wax to the formula, you can use them not just indoors but also outdoors knowing that the elements cannot damage the poison.

Package-wise, you can choose between a 4-pound bag and a 20-pound bucket. Though most people should find the first option more than sufficient, the bucket will let you store the nuggets without worrying that rodents might eat through the bag.

In short, wet or damp areas, Neogen Ramik Green Rodenticide Nuggets will prove suitable for them all, attracting and exterminating rodents as easily as the most expensive rat and mice killers.

Stationing the Bait

D-con Cholecalciferol Mouse Poison Bait Station is packing an actual bait station, just as the name suggests. Of course, besides the trap, this product also includes 18 bait refills, hence its spot on this list. The compact and low-profile station is essentially tamper-resistant, so you don't have to worry about pets and kids screwing with the trap. It is also weather-resistant, which means that you can set the trap outdoors without worrying that it might start raining and that the poison will get wet and vaporize or lose its effectiveness.

Looking at the formula, even though the poison is made from >99% food-grade ingredients, you'll start seeing visible results within 3 days and most rodents will not live to see the 2nd day. Still, we're not crazy about the bait refills, primarily because they're very soft and easily breakable, so you'll occasionally see crumbs here and there.

The good news is that, since they're as soft and breakable as they are and, thanks to the trap's low-profile design, this bait station will fit attics, most kitchens, pantries, basements, sheds, garages, laundry rooms, bathrooms, and even living rooms and bedrooms. Just set the trap and, soon enough, the rodents will be gone.

What Are Mouse & Rat Poisons?

Showing mercy when you can is an admirable approach. Unfortunately, this is not always an option. Sometimes, you have to be ruthless, even merciless. Rodents can be cute, sure, but they carry diseases, eat crops, and destroy property, so eliminating them is, at times, an unfortunate necessity. To that end, you can try these mouse and rat poisons. They're effective formulations that use different ingredients but achieve comparable results: killing rodents within 2-5 days, depending on the product.

There are poisons that can be used both indoors and outdoors, and these are the ones that we have gathered here. They're usually fine with mold, moisture, and most elements, but some will not be able to survive considerable downpours, so make sure you've chosen the right place first. Shaped like nuggets, cubes, or small chunks, these rodenticides double as attractants more often than not, incorporating flavorants and food-grade ingredients to make the rodents feel inclined to try them.

As you can imagine, these poisons work especially well with rat traps, so you can look into them too. We've also reviewed mosquito and fly killers before, which are excellent tools in their own right.
