Buying Guide

Rat poisons are products designed to effectively and efficiently control the rat population, whether it be in a residential, commercial, or agricultural setting. These products contain potent ingredients that, once consumed by rats, can eliminate them, thereby helping to prevent the spread of diseases and damage to property.

Here is a generalized buying guide to help you make an informed decision when purchasing rat poisons:

• Safety: The primary concern when buying rat poison should be the safety of people and non-target animals in your household. Some products have safety measures in place, such as tamper-proof bait stations, to prevent accidental ingestion.
• Effectiveness: Not all rat poisons are created equal. Look for products that are proven to be effective against the type of rat you’re dealing with. Some products are better suited for larger rats, while others are designed to eliminate smaller mice.
• Mode of Action: Rat poisons work in different ways. Some cause internal bleeding (anticoagulants), while others disrupt the rat’s nervous system (non-anticoagulants). Understand the mode of action and choose the one that suits your situation.
• Form Factor: Rat poisons come in different forms – blocks, pellets, or liquid. Your choice will depend on where you plan to use the poison. For instance, block-type poisons are great for outdoor use as they are weather resistant.
• Price: Lastly, consider your budget. While some high-end brands offer advanced features and greater effectiveness, there are also budget-friendly options that do not compromise on quality.

3. JT Eaton Bait Block Rodenticide

This rat poison is manufactured by a US-based company known as JT Eaton. They specialize in making high-quality pest care products, including products for rats, mice, bedbugs, and other insects, etc.

The active ingredient present in this JT Eaton Bait Block rodenticide is Diphacinone 0.005%, which is a first-generation anticoagulant and kills rats by causing internal bleeding upon consumption.
The peanut butter flavor of these rat bait blocks makes them suitable for attracting a wide range of rodents, especially rats and kills them effectively after a few days of feeding.

JT Eaton bait blocks can be used in a number of places indoors, such as the attic, basement, garage, laundry room, etc. This rodenticide can be easily used in a bait station.

It should be kept in mind that it is not weather-resistant bait and can get washed away in rainwater, therefore should be used indoors only.

In addition, it is an effective but slow-acting rat poison and might take up to a week to show positive rodent-killing activity, which might not be liked by many customers who want a quick rodent-killing action in their home.

Furthermore, it is a toxic substance, therefore, should be used with extra caution around children and pets.

Anyhow, it is one of the most affordable rodent-killing products available in the market, which helps get rid of rodents in your home smoothly.

Customer Reviews

The JT Eaton Bait Block Rodenticide is largely appreciated by users for its effectiveness in eliminating rodents.

Many find it user-friendly and appreciate the irresistible peanut butter flavor that lures in rats and mice.

Also, the product’s crumbly nature might cause a mess, necessitating thoughtful storage. In another review, the product’s efficacy in reducing rodent populations is lauded, but its performance seems to vary among different rodent species.

Some users also reported that the seeds inside the bait could block the holes, posing difficulties when placed on a bait box rod.

Despite a few downsides, it’s considered a worthy product for rodent control.

Instructions to Use

• Put on gloves before handling the bait blocks to ensure safety.
• Place the bait blocks inside the bait stations.
• Position the bait stations along walls or in areas where you’ve noticed rodent activity.

Farnam Just One Bait Poison is one of their most effective rat-killing products commercially available.

Although many people criticize using such poisons, it is one of the fastest and most effective ways to get rid of pesky rodent infestations.

Upon consuming this poisonous bait, rats begin to bleed internally, ultimately leading to death. The whole process takes about 4 to 5 days.

It works remarkably well for warfarin-resistant Norway rats and other stubborn roof rats and house mice.

Just like other rat-killing products, it should be kept away from the reach of children and pets.

6. D-Con Refillable Corner Fit Mouse Poison Bait

It is another great product designed to get rid of the notorious mice and rats easily.

It is manufactured by a UK-based company known as Reckitt Benckiser. They produce and distribute rodent control products in the United States, including traps and baits for trapping and killing rats and mice.

The active ingredient present in this bait is Diphacinone, i.e., a first-generation anticoagulant that works by inhibiting enzymes involved in blood clotting and causes internal hemorrhage leading to death.

It is also toxic to humans and other mammals if inhaled, ingested, or touched with bare hands; therefore, it is advised by the manufacturers to minimize exposure to the product and always wear gloves while handling the bait, bait station, or the corpse of the rodent.

This rat and mouse poison is extremely toxic to mammals, birds, and other wildlife. Therefore should be kept out of the reach of children and pets. Dogs, other mammals, and birds might be poisoned if they feed upon animals that have eaten this bait. That is why care should be taken.

Also, it should not be applied directly to water due to its environmentally hazardous effects.

According to customer reviews, d-con Refillable corner fit mouse poison bait and bait stations work extremely well.

Each d-CON Corner Fit bait block can kill multiple mice. In addition, the bait station has a viewing window, making it extremely easy to check whether the rodent has consumed the bait. Mice enter the bait station, eat the bait and leave to die somewhere else, mostly outside the house.

This product comes with 6 baits and refillable bait stations making it very convenient to use. It is a weather-resistant bait station and can be used indoors or outdoors.

It is perfect to be used in corners, attics, behind appliances, basements, garages, sheds, and around tight places in the house.

7. Ratx Rat Bait Pellets

These rat bait pellets are produced by the American company known as Ecoclear Products, which specializes in providing natural rodent control and insect control products.

These rat bait pellets are another efficient product designed to kill rats and mice effectively.

These rat bait pellets are different from other products as they contain food-grade active ingredients which are non-toxic to humans, pets, and wildlife.

The major active ingredient present in this product is Corn gluten and other vegetable and cereal-derived ingredients, making it lethal for the unique stomach of rats.

RatX damages the stomach lining and eliminates all messages to the brain to drink water. As a result, after consuming a single feeding within a day or two, rats feel dehydrated, their blood gets thicker, and they lapse into a coma and die.

Manufacturers claim it to be a very humane death for rodents as they don’t feel the pain and simply die by falling asleep.

Upon using correctly, death of the rats occurs within 4 to 5 days of feeding, depending upon the size of the rodent.

Since rats become extremely lethargic after consuming the bait pellets, many rats might be seen in the house as they cannot react to the outer stimuli effectively. Rats and mice naturally eat up to 10% of their body weight per feeding.

RatX is available in different sizes, including 8 oz, 1, 3, and 25-pound bags. These rat bait pellets are also present in 2, 4, and 8 packs of pre-measured 3 oz bait trays.

It should be noted that voles, gophers, and moles have a different digestive system than mice or rats and will not be killed by this product.

Customer Reviews

EcoClear Products’ humane rat solution has become a hot item on E-Commerce sites.

While one user found its performance varied, with rodents sometimes overlooking the bait or only being mildly inconvenienced, others noted improvement when mixed with peanut butter.

Another reviewer highlighted the product’s eco-friendliness but emphasized its varying effectiveness, the need for strategic placement, and pet safety.

Despite potential challenges, they concluded the product could be an effective solution with patience.

Instruction To Use:

1. Before using these pellets, manufacturers should remove all other food sources from the treated area.
2. RatX pellets can be placed in any area where rat or mouse activity is seen, particularly along the walls and holes.
3. The product can be put in a bait station or simply in sandwich bags or cling wraps.
4. These bags can then be placed along the walls and void spaces from where rats might make their way in and out of the house.
5. Ratx Attractant or empty bait trays can also be purchased to keep the bait pellets in them.
6. Refill the trays or sandwich bags regularly to deal with a bigger infestation problem.
7. Continue to bait until rat or mouse activity ceases.
8. An indicator of consumption will be fecal droppings bleached in color and up to 3 times larger than normal.

Understanding the Varieties of Rat Poisons

The U.S. Environmental Protection Agency classifies rodenticides into three main categories: first-generation anticoagulants, second-generation anticoagulants, and non-anticoagulants.

First-generation anticoagulants, including Warfarin, Chlorophacinone, and Diphacinone, usually require multiple ingestions by rodents to be effective and are less toxic to humans and other animals. These anticoagulants interfere with blood clotting, leading to death from excessive bleeding within four days to two weeks.

Second-generation anticoagulants, such as Brodifacoum, Bromadiolone, Difenacoum, and difethialone, are more potent and can kill rats with a single feeding by causing internal bleeding.

Non-anticoagulants have distinct modes of action. For example, Bromethalin is a neurotoxicant that disrupts energy production in central nervous system cells, leading to paralysis and death. Cholecalciferol, a type of Vitamin D3, becomes lethal to rodents when consumed in excessive quantities.

Lastly, Zinc Phosphide releases toxic phosphine gas in the stomach, interrupting cellular energy production and causing organ damage, particularly to the heart, brain, kidneys, and liver.

Final Thoughts

Rat poisons are effective for rodent control, often proving more successful than traps. However, they pose risks to pets, children, and even adults on direct contact or ingestion, warranting safety precautions like glove use and secure placement in bait stations.

Rats may die in hard-to-reach areas, complicating corpse removal, and these poisons can harm wildlife and the environment.

Despite these issues, their efficiency in eradicating multiple rodents with a single dose is notable. The EPA stresses not scattering rat poison without bait stations to minimize associated hazards.
