Rats Eating Bait But Not Dying

Rats eating bait but not dying is a common problem that can be a real headache to deal with. Here’s some information on the issue and what you can do to resolve it:

Possible Reasons for Rats Eating Bait But Not Dying:

  • Incorrect placement of the bait: Rats tend to avoid areas that don’t feel safe, so if the bait is not placed in a secure location, they may not consume it.
  • Ineffective or insufficient amounts of poison: If the bait is not strong enough or there’s not enough of it, the rats may not consume enough to be affected by it.
  • Resistance to certain types of poison: Some rats may have developed resistance to certain types of poison, making it difficult to eradicate them.

What To Do When Rats Eating Bait But Not Dying?

So, you’ve tried baiting rats, but they seem to be eating the bait and not dying. It can be a frustrating and confusing situation, but here’s what you can do:

  1. Evaluate the situation:
    • Check the bait placement: Is it in a location that feels secure to the rats?
    • Check the amount of bait: Is there enough bait, and is it strong enough to be effective?
    • Consider the possibility of resistance: Have the rats developed resistance to certain types of poison?
  2. Seek expert advice:
    • Consult with a professional pest control company: These experts can evaluate the situation and determine the best course of action.
  3. Take preventative measures:
    • Seal up entry points to your home or business to prevent rats from entering in the first place.
    • Practice proper sanitation: Keep your property clean and free of food scraps or other attractive materials that may attract rats.

How Much Poison Does A Mouse Need To Eat To Die?

It depends. Well, the answer is not so simple and depends on various factors. Here’s some information on the topic:

  • Anticoagulant poisons: These are the most common types of poisons used for rodent control, and it usually takes between 0.5-2 mg of poison per kilogram of the mouse’s body weight to be effective.
  • Non-anticoagulant poisons: These are typically more potent and require smaller amounts of poison to be effective, usually around 0.1-0.3 mg of poison per kilogram of the mouse’s body weight.

It’s important to note that the amount of poison needed to kill a mouse also depends on the method of delivery. For example, if the poison is delivered through the bait, it may take several feedings for the mouse to consume a lethal amount.

Where Do Mice Go After Eating Poison?

Here’s what you need to know about where mice may go after consuming poison:

  • Some mice may die in plain sight: Depending on where the poison was placed and how it was consumed, some mice may simply die where they were when the poison took effect.
  • Others may retreat to hidden areas: Many rodents are instinctively programmed to seek out hidden areas when they feel ill or in danger. Poisoned mice may retreat to their nests or other secluded areas to hide and potentially die.
  • Some may be eaten by predators: Poisoned mice can become easy prey for predators such as birds of prey, cats, or other animals. These predators may consume the poisoned mice and may also be affected by the poison.

Do Mice Take Poison Back To Their Nest?

Here’s what you need to know about whether mice take the poison back to their nest:

  • Some mice may take the bait back to their nest: Depending on the type of poison used, some mice may consume the bait and then return to their nest or hiding place to die.
  • Others may not: However, not all mice will take the bait back to their nest. Some mice may consume the poison and then die in the open, making them easier to find.
  • It depends on the type of poison: The extent to which mice take the poison back to their nest may also depend on the type of poison used. Some types of poison are formulated to make the mouse thirsty, which can cause them to leave their hiding place in search of water.

It’s important to use poison according to the manufacturer’s instructions and to take precautions to prevent unintended exposure to pets or other animals.

Is It Better To Poison Or Trap Mice?

Poison can be more effective and traps are more humane. Here are some things to consider when deciding between poisoning or trapping mice:

  • Poison can be more effective: In some cases, poison may be a more effective way to eliminate a mouse infestation. When used properly, poison can be lethal to mice and can also kill multiple mice at once.
  • Traps are more humane: Traps are generally considered a more humane way to get rid of mice. Instead of killing the mouse with poison, traps allow you to capture the mouse and release it elsewhere.
  • Poison can be dangerous: One of the biggest concerns with using poison is the potential danger it poses to pets or other animals. If you have pets or children, using poison may not be the best option.
  • Traps require more effort: Traps require more effort on your part, as you will need to check them regularly and dispose of any trapped mice. Poison, on the other hand, requires less effort once it has been set up.
  • Personal preference: Ultimately, whether to use poison or traps may come down to personal preference. Some people may feel more comfortable using traps, while others may prefer the convenience of poison.

Why Is My Rat Poison Not Working?

There are several reasons why your rat poison may not be working as expected, including:

  • Rats may not be taking the bait: One possible reason why your rat poison isn’t working is that the rats simply aren’t taking the bait. Rats can be cautious creatures, and if they sense that something is off with the bait, they may avoid it altogether.
  • The poison may not be strong enough: Another possibility is that the poison you’re using may not be strong enough to kill the rats. Rats are notoriously resilient, and some strains of rats may be resistant to certain types of poison.
  • The poison may be expired: Rat poison has a shelf life, and if your poison has expired, it may not be as effective. Make sure to check the expiration date on your poison and replace it if necessary.
  • There may be too many rats: If you have a large infestation of rats, it’s possible that your poison simply can’t keep up with the demand. In this case, you may need to use multiple traps or switch to a more powerful poison.
  • The rats may be getting poisoned elsewhere: If you’re using poison outdoors, it’s possible that the rats are getting poisoned by other sources as well, such as a neighbor’s poison or bait stations set up by a pest control company.

Can A Rat Live After Eating Poison?

Yes, if a rat consumes a lethal dose of poison, it will die within a few days. However, there are some cases where a rat may survive even after eating poison. Here are some reasons why this might occur:

  • The rat may not have eaten enough poison: Rats need to consume a certain amount of poison in order to receive a lethal dose. If they only eat a small amount of poison, they may not die, but they may still experience negative side effects such as illness or weakness. Read above for how much poison a mouse needs to die.
  • The poison may not be strong enough: Some types of rat poison are not as strong as others, and rats may be able to survive after consuming them. Additionally, rats can build up a tolerance to certain types of poison over time.
  • The rat may receive medical treatment: If a rat is discovered to have eaten poison, it may be possible to save its life with medical treatment. Some veterinarians are able to administer an antidote that can counteract the effects of the poison.
  • The rat may be resistant to the poison: Just like humans, rats can have different levels of resistance to poison. Some strains of rats may be more resistant to certain types of poison than others.

How Do Poisoned Rats Behave?

When rats consume poison, their behavior can vary depending on the type and amount of poison ingested. Here are some common behaviors that poisoned rats may exhibit:

  • Lethargy: Poisoned rats may become lethargic and inactive, as the poison can cause weakness and fatigue.
  • Disorientation: Some types of poison can cause rats to become disoriented and confused. They may move slowly or appear to be stumbling.
  • Increased thirst: Poisoned rats may drink more water than usual, as some types of poison can cause dehydration.
  • Loss of appetite: Poisoned rats may lose their appetite and stop eating, as the poison can cause nausea and vomiting.
  • Bleeding: Certain types of poison can cause internal bleeding in rats. If you notice blood in the rat’s feces or urine, it may be a sign of poisoning.


In conclusion, dealing with rodents can be a frustrating and time-consuming process, and it’s important to be patient and persistent in your efforts. Whether you choose to use traps, poison, or other methods of pest control, it’s essential to follow all safety precautions and instructions carefully.

Remember that prevention is key when it comes to rodent infestations, so taking steps to eliminate potential entry points and keep your property clean and clutter-free can go a long way in deterring these pesky creatures. So stay vigilant, stay safe, and don’t let those rats and mice get the upper hand!
