Inevitably, it is us human beings whom rodents  prefer as friends. The big question would be: why do rodents prefer living near human beings?

What is rat killer?

Rodent killing substance, also known as a rodenticide is a chemical used for killing rodents. It is made of metal phosphides, anticoagulant, and maybe a little dose of vitamin D. Some rat poisons are lethal after a single exposure while some require more than a single exposure. Also, some work for a longer period while others for a short period.

Besides being toxic to rodents, rodenticides can also affect humans, dogs, cats, or any other animals that scavenge on dead rats.

How does rat killing substance work?

Rat poison, basically fights vitamin K in the rat’s body system and gradually depletes it to zero level. This vitamin is essential for blood clotting. When they eat the poison, it goes to the stomach but does not start reacting there, so the rat will not barf. The poison starts reacting when it gets to their bloodstream and gradually weakens their immune system. It may take up to 3 days before they lose all vitamin K. This leads to tears and rips inside the animal’s body, thus causing the rat to die of internal bleeding.

How long does rodent toxin take?

Since there are different types of rat poison, it takes different time for each of them to react. Some respond immediately, while others take some days to react. It is best to buy the one that takes some days because these rodents observe the first rat that eats the poison to see if it reacts to the food. But when it takes more than one day, they hardly trace the cause of death.

You don’t have to spend much to control rodents in your house anymore. I’ll be showing you an effective homemade recipe for rat poison.

Baking soda rat poison

Step 1. Wear your disposable gloves. Since we are talking about poison, it is important that proper safety measures are taken to prevent any harmful effect.

Step 2. Put 1 cup of cornmeal or flour and 1 cup of powdered chocolate or sugar in a container. Add 1 cup of baking soda and mix thoroughly until the mixture blends evenly. The chocolate or sugar (whichever one you use) will attract the rodents, while the baking soda will do the killing after they have consumed the mixture

Step 3. Look for jar lids and half-fill them with the rat bait made in step 2

Step 4. Search through the building to find where rat droppings are and put the baited jar lids in those locations. It is most likely that the rats will return to these areas.

Step 5Monitor the areas from time to time to see the outcome of the homemade rat poison. Once you stop seeing new droppings, watch out because what you will start seeing are dead rats.

Your dogs can be affected by eating rodent poison or eating rats that have ingested the poison. In any of the cases, a vet should be visited as soon as possible to save the dog’s life. Rat poison in dogs can be fatal if prompt medical care is not administered.

How does this affects your dog?

These toxins act as an anticoagulant by reducing the amount of vitamin K in the body. This vitamin is essential for blood clotting. It takes between 1 to 5 days for the vitamin K to be completely depleted, after which signs of sluggishness begin to manifest. Death follows immediately. So rat poison in dogs should not be taken lightly.

There are two types of rat bait; 1st generation and 2nd generation rat poison. The first generation drugs are those that work within a short period and require more than a single ingestion for them to be effective. The second generation drugs are drugs that work for a longer period and a single dose is enough to make the action fatal.

What are the symptoms to look out for?

If your dog eats rat poison, you may not see the effect immediately. How long does it take before you see the effect? It may take 1 or up to 5 days for the symptoms to manifest. If you notice any of the following signs listed below in your dog, visit your vet doctor immediately to save its life.

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 killers 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 killers 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.
