This is arguably the cheapest of the rodenticides found on Amazon.

While the price is attractive and effects quick, the packaging makes it potentially dangerous especially to children.

Tomcat Rat Killer

It is arguably the safest rat killer poison gadget available.

Given its price on Amazon, the rat feeding station makes it a bargain.

However, the station slows down the speed at which the rats eat the bait since only a few fit in.

The station may act as a trap locking an already suffocating rat inside to its death.

The resulting bad odor would be disturbing.

Humane traps have been known to be methods of choice in dealing with this menace. While humane traps are rather safe to human beings and their pets, they are proven not to be effective over time. Inefficiencies of this method include the following:

1. Its inability to trap more than a given number of rats or mice depending on its size.
2. It is known to mechanically malfunction after a period of use.
3. The trap does not necessarily kill the rats, and some may escape when trying to kill them.
4. Some rodents are strong enough to escape from the traps.
5. Traps are time-consuming and take long to eliminate rodents.

Types of rat poison and how they affect humans and pets

Substances such as fish oil, molasses, peanut butter, ground meat, vegetables and grains are used as baits.

While the bait is meant to attract the rodent, children and pets such as rabbits, monkeys, cats and dogs may also be tempted to eat or inhale the poison. This could potentially have adverse or fatal consequences.

Rodenticides cause adverse effects when inhaled, eaten or put in touch with the skin of a human being or a pet. This is particularly due to the reactive chemicals used in making the poison compound.

The effects of this poisoning on pets and human beings may at times take while to its slow nature. Therefore, it is important to understand different categories of rodenticides in order to wisely consider the best poison to buy.

Rodenticides can generally be classified into anticoagulants, vitamin based and bromethalin.


Anti-coagulants are rodents poisons that contain chemicals whose action in the body take relatively long time. The effect may take up to 48 hours to be effective. The active ingredient in this rodenticide prevents clotting of the blood.

The poison may exhibit the following sign on your children or pet depending on the dosage ingested. Breathing difficulties, bloody urine, bloody vomiting, coughing and bleeding and other signs.

However, this rodenticide contains a readily available antidote called vitamin K1 taken between 3-4 weeks. Warfin and fumarin are some of the best-known anti-coagulants.

Vitamin Based

Also known as Cholecalciferol, it is composed of poison pellets that flood a rat’s system with soluble fats. It is faster and more dangerous than anti-coagulant taking up to a day to be effective. Too much of the vitamin in the system lead to excess calcium in the body.

This affects the central nervous system, kidneys, cardiovascular system and digestive tract. There is no known antidote if accidentally ingested. Only a variety of therapy treatments and aggressive blood monitoring up to one month is used.


This is the most lethal rodenticide which acts as a neurotoxin when ingested. The poison takes a few hours acting on the brain and the liver resulting in brain swelling. Shortly after the poison may cause tremors, paralysis, seizures and even death. Unfortunately, if a human being or a pet ingests, there is no antidote part from supportive care. Bromethalin is often found in mole rodenticides and rarely in rats or mice poison.

Aluminum, zinc, phosphides and Calcium

These are mostly found in mole rodenticides and on rare occasion in mice and rats baits. From four hours, the poisons normally release toxic gasses into the system causing bloating, vomiting and other abdominal pains.

The poison does not have a known antidote. For this reason proactive, fast decontamination is required if accidentally ingested as it may easily cause liver damage and shock or collapse.


The market has hundreds of rat and mice products which are often effective on rats. While choosing what to buy, critically check for products that leave the environment safe for you, your children and pets but at the same time act the fastest possible way to get rid of your problem.
