There is the conceivable possibility that you may pass away from unintentionally swallowing rat poison.

Can rat poison kill a human?

Yes, consuming rat poison might be fatal to people.

Ingesting even a small amount of the poisonous compounds used in rat poison to kill rats can result in significant health issues in people, including internal bleeding, organ damage, and even death. The type and quantity of rat poison consumed, the individual’s age, weight, general health, and the period that passed between ingestion and seeking medical attention all affect how severe the health impacts are. It’s crucial to remember that rat poison is not designed for human consumption and should only be used to manage rodent populations. It’s critical to seek quick medical attention if you believe someone has consumed rat poison.

Can rat poison kill a human in 12 hours?

Depending on the type and quantity of rat poison consumed and the individual’s age, weight, and general health, ingesting rat poison can result in significant health issues, including death, within a short time.
Sometimes, consuming a significant dose of rat poison can have immediate and severe health effects, including death. However, this isn’t always the case because the time it takes for rat poison to kill an animal can differ significantly and depends on various conditions.

Whatever the circumstances, it’s critical to remember that rat poison is a hazardous toxin that, if consumed by humans, can result in serious harm. It’s crucial to get emergency medical help if you believe someone has swallowed rat poison.

The Required Amount Varies

It is not feasible to offer a precise response to the issue of how much rat poison is necessary to kill a person because there are so many distinct factors at play in this scenario.

The sort of rat poison in issue and how it kills rats will have some bearing on the answer to this question. In addition to that, it will rely on the following:

  • Your body weight
  • your age
  • your genetics

To generate symptoms in humans, rat poisons that depend on warfarin or thallium as their active ingredient need a higher consumption rate than the more hazardous second-generation active chemicals, such as difenacoum, brodifacoum, and bromadiolone. These second-generation active ingredients include:

Healthy Adults Would Have to Eat a Lot of Food to Die

To be fatally poisoned by rat poison, you would typically have to swallow an extremely high dose of the substance. Ingestion of an unintentional dose of rat poison would likely result in the death of a tiny percentage of humans.

But You Can Get Very Sick – Especially Children

Even while it is improbable that you would pass away if you consume rat poison by mistake, you might end up extremely unwell. After eating around one “mouthful” of bait, there have been reports of situations in which children have difficulty bleeding.

In the example of brodifacoum, a frequent active component in rat poison, a kid weighing around 10 kilos would need to ingest about 1.5 milligrammes for their regular blood clotting to be messed up. This is because brodifacoum slows down the body’s ability to form blood clots. The vast majority of typical baits contain less than 50 mg per kilogramme of bait. To put it another way, a youngster would need around 30 grammes of appeal to experience those adverse consequences.

Because this amounts to just a few tablespoons, it is within the expected range that a young kid may consume without their parent’s knowledge if they come across a set of baits.

Certain People Are in a Greater Danger than Others

Most rat poisons achieve their lethal effect by preventing rats’ blood from clotting generally to an extraordinary degree. Because of this, someone already taking medication to thin their blood would need to drink a far lower dose of the poison to see any noticeable effects or even to pass away. In this scenario, the anticoagulant included in the poison would collaborate with the blood thinner given to generate even more severe consequences, which would need a visit to the emergency department.

People with liver problems are at an increased risk of being adversely impacted by blood-thinning rat poisons, along with those with other ailments that might raise this risk.

Human Poisoning Symptoms After Consuming Rat Poison

Spend a moment familiarising yourself with the probable symptoms linked with the consumption of rat poison. Due to this, you will find it much simpler to recognise potential problems at an earlier stage.

You may experience the following:

  • Nosebleeds without an apparent cause
  • Gum bleeding without an obvious reason
  • Bloody diarrhoea
  • Blood in the pee
  • Shortness of breath
  • Severe tiredness

In most cases, if you have more than one of these symptoms, you may have swallowed rat poison. If you detect great weariness, the rat poisoning has already evolved to a very hazardous stage, and you may likely die.

Ignoring Symptoms May Lead to Death

It can cause significant issues for oneself if one disregards the signs and symptoms of rat poison in people and does not seek treatment. Comas, internal bleeding, respiratory difficulties, seizures, heart attacks, shock, and liver failure are some of the possible outcomes of this condition. Sudden death is another possibility, as is the likelihood that one of the earlier symptoms would ultimately lead to the patient’s demise.

Always Dial the Number 911 If You Have Reasons to Believe That Someone Has Consumed Rat Poison

Because the consequences of rat poison in people may grow and worsen, even leading to death if left untreated, you should always call 911 if you have a strong suspicion that someone took rat poison or if you know for sure that someone consumed rat poison.

In the meantime, they could recommend that you take activated charcoal or syrup of ipecac. However, this is not guaranteed. They will inform you whether a trip to the emergency department is required for you to get treatment.

Methods to Prevent Humans from Consuming Rat Poison

Even though you would have to drink a significant amount of rat poison to pass away from its effects, there is still a risk that even a small amount might have substantial adverse effects on your health. Because of their smaller frame sizes, this is especially important for youngsters to remember. As a result, you need to exercise extreme care and take the necessary preventative measures to avoid swallowing any rat poison by mistake.

Be Cautious When Employing It

When setting up the bait, you should take extreme caution to avoid touching the real poison. Additionally, after finishing, you need to wash your hands properly.

Make Sure That It Is Not Reachable

If you have young children living in your house, you must ensure that the rat poison is constantly out of their reach. You do not want your youngster to stumble upon it and consume it by mistake.


Instruct Your Children About the Risks That Are Out There

Make sure that even at an early age, your children know that the rat poison is not intended for them to consume and that it may have severe consequences if they do. Because of this, their likelihood of consuming it is reduced, even if they get it by mistake.

Choose bait stations that are tamper-proof.

If you are required to use rodenticide, you should always choose items that comply with the regulations that state the bait for the rodenticide must be enclosed in a station that cannot be opened or tampered with. It would be best if you considered exchanging outdated items with tamper-proof bait stations as soon as possible.

Remember that pets need less food.

Remember that pets are also in danger from rat poison, but since they have a smaller body mass, they would only need to swallow a smaller amount for the poison to impact them negatively.

Additional Reasons to Avoid Poison

Suppose the potential for harm to people and animals is not enough to convince you to avoid using rat poison. In that case, you should also consider a few additional potential problems. The rat will not die instantly if you poison it with rat poison. This allows it the time to return to its nest, where it will ultimately perish. Consequently, you will be unaware of the location of the dead rat, and you will need to search for it, which may be a challenging task. In addition, rat poison causes misery while it is working, so the rat will be in agony for many days after being exposed to it.

Consider using an approach to rodent management that is both speedy and kind, such as preventive measures or traps with spring-loaded jaws.
