Don’t want to spend money or use harsh chemicals? No problem – there are plenty of DIY ways for killing mice and rats. Click here for more about homemade mouse poison.

How Quickly Can I Expect It To Work?

Mouse poisons come in different varieties.

Some ways poisons work include:

  • Cholecalciferol: This is a common ingredient in rodent poisons, and is otherwise known as Vitamin D3. What it does is cause dangerously high calcium and phosphorous levels in the body, leading to rapid kidney failure.
  • Zinc Phosphide: When a mouse ingests this rodenticide, acid in its stomach converts it into zinc phosphine, which is a very toxic gas. This subsequently kills the animal.
  • Bromethalin: This substance will damage the central nervous system in a way that causes high pressure in the brain, killing mice.
  • Anticoagulants: A substance that works like an anticoagulant (AKA, blood thinner) inhibits vitamin K synthesis, which leads to the mouse’s blood not being able to clot normally. This also makes blood vessels leaky, which causes internal bleeding. In general, anticoagulants kill mice within 2-3 days and kill rats within 3-6 days.

MiceThe length of time from ingestion a lethal dose to a death varies with each substance. Vitamin D3 in high doses will usually take about 12-48 hours to be fully lethal. Anticoagulants can take several days to work, while Zinc Phosphide works somewhat faster.

Pellets are a form of mouse poison that works well on various animals, including rats and mice. To learn more about mouse poison pellets and how you can use them, go here.

Single Feed and Multiple Feed Mouse Poisons: What is the Difference

There are two types of mouse poisons – single feed and multiple feed rodenticides.

Single Feed Rodenticide

Single feed mouse poisons only need to be eaten once for a pesky rodent to die. They are used for persistent or chronic rodent situations.

Brodifacoum and bromadiolone are two examples of single feeding rodenticide are contained in Farnam Just One Bite II, Havoc Rat and Mouse Poison Pellets products.

Multiple Feed Rodenticide

Multiple feed poisons, on the other hand, require several doses to kill rodents. They are designed to kill the mouse over a period of time, as it continues eating poison. So, should be used in maintenance situations – when there is already a mouse problem, but you don’t want it to get worse.

Multiple feeding rodenticides are also known as anticoagulants because they work by breaking down the blood’s ability to clot, which causes death from internal bleeding or hemorrhage. If you’ve heard of the best rat poison before, it is usually an anticoagulant that claims its victims first by making them bleed out internally and then second through dehydration.

One example of a multiple feed mouse poison is diphacinone. JT Eaton Rodenticide is a block-like bait that contains 0.005% Diphacinone.

What to Do If It Isn’t Working

If you’ve been using mouse poison products with no results, there may be more than one thing to blame. First of all, there’s been an epidemic of mice who are resistant to mouse poisons, specifically to anticoagulants. They may be ingesting it without any results.

Another explanation could be that you’re putting the mouse poison in the wrong places. Mice might not even have a chance to get at it. There also might not be enough mouse poison set out, meaning that some of the pests can get at it, while others are too late and get thereafter it’s already gone.

Poison can kill rats and mice in as little as one feeding.

A way you can try and overcome these obstacles is by using products that specify they’re for resistant mice and being diligent about placing enough mouse poison. Also, make sure you’ve got the right places picked out. Watch areas in your home for droppings and other signs of mouse activity, and place mouse poison accordingly.

Hardware stores are good not only for lumber and tools but for things like pest control as well. And where better than one of the biggest stories in the country? Details on Home Depot mouse poison can be found here.

For inside the Home

When you’re looking to get rid of mice inside your home, you’ll need good mouse poison products. And there are other things to consider about the product you’re using when it’s indoors as opposed to outside.

For example, if you have kids, you’ll want to take more precautions as to your mouse poison use. The same precaution will apply to a home with indoor pets, as well.

  • d-Con Mouse Poison Bait Stations: This company has thought of a product that uses child-proof bait stations, each with a block of poisonous bait inside it. The mouse will smell the bait block, crawl inside the plastic container, eat off the mouse poison, then crawl back out. Death can come from only single feeding, although it may take longer if the mouse only ate a very small amount. This is a great product to use in a home with small children or pets that you want to keep safe from harmful ingredients.

Kill the Smell

Most mouse poisons try and have a desirable smell for them to attract the mice. But what is considered good to a mouse might not necessarily be good to a human, and can leave an unattractive smell lingering in the air.

You can combat this using essential oils in your home that could mask the smell for you. Soak a cotton ball in a scent like peppermint or orange and leave it out on the kitchen or bathroom counter, or use an oil diffuser.

Decomposing Mice in the Walls and Attic

Another problem you may encounter is the smell of decomposing mice. They can die in your walls or attic and leave a “dead” smell behind.

Here are some solutions for the problem:

  • Dehydrating mouse poisons
    Dehydrating mouse poisons help prevent a decaying smell in dead rodents. And if you are diligent about trying to find any dead rodents killed by the poison, you can do a lot to keep your house smelling normal.
  • Claw Reacher Grabber
    You could even buy one of those long poles with a claw on the end to grab any dead mice you might find behind walls or in hard-to-reach places.

For the Outdoors

Mice aren’t just a problem inside the home; they’re an issue outdoors, as well. They’ll often live outside and come in and out of your house at will.

It’s a good idea to have mouse poison outside for them to run into, and some places you can put it include:

  • The wood pile.
  • Around the foundation of your house.
  • Around basement windows.
  • Nears door frames.

The JT Eaton Bait Block Rodenticide is weather-resistant and suitable for use outdoors:

Poison Mouse Traps: The Best Out There

Poison for rodents comes in different forms: liquids, pellets, powder, bars, etc. One sub-type you can get is a mouse poison trap. This isn’t a trap that will keep the mouse inside it until you can set it free or kill it yourself, it’s a way to hold the mouse poison in bait stations.

Mouse poison is deadly to small rodents, and unfortunately, is also deadly to humans. It can hurt a person’s digestive tract, central nervous system, and blood vessel integrity if ingested mouse poison.

Poison bait stations are plastic containers you put a poisonous substance into, then lock up so that small children or pets can’t get to them. A mouse, however, can scurry inside and take some of the mouse poison.

Frequently Asked Questions

What happens to mice when they eat poison?

When a mouse eats poison, it instinctively knows that the only antidote is to run away and poop out the poison.

It's also worth mentioning that if you let these mice go off into the wild and continue to eat a diet of poisonous pesticides without protection, they will never know what it's like to be healthy mice because before too long they'll die from those pesticides.

The key point here is to avoid letting these free-living poisoned mice reproduce (either with each other or through their reproduction) because once they produce offspring, those offspring grow up eating more poisonous food. And once again, this increased exposure will make generations after side effects more toxic as well as increase fecal contamination in forested areas, which could expose predators to these mouse poisons.

If you're not 100% sure that a wild mouse has eaten poison and doesn't have any symptoms, then the smart move is to just leave it alone. If you don't see any symptoms of poisoning, then your guess was wrong (no harm done) and if there are symptoms of poisoning, then rescuing it could potentially cause more problems for other living things in the area than leaving it alone would.

What to do if your dog eats mouse poison?

If you find your dog vomited after eating a poisoned mouse, it's probably best to contact your vet for advice and treatment. For instance, if the mouse had eaten poison that is known to be toxic to humans, like rat poison, then the vet may treat the dog with activated charcoal and other treatments depending on the circumstances.

It's also important to keep in mind that some mouse poisons can be fatal to dogs, even though they are not harmful to humans. Rodenticides are one of these because they can cause bleeding in the stomach, intestines, or brain.

How to inject poison into walls to kill mice?

Unfortunately, there is no easy way to do this.

Mouse poison can't be injected into walls because the wall would need to somehow have an opening in the middle of it or something high up where the mouse could reach it. Either you're going to have a hole in your wall big enough for a mouse's arm (probably) or you're going to need a stepladder or something so that they can reach the mouse poison.

Can I use rat poison?

For the most part, yes, you can use rat poison on mice, and mice poison on rats. However, there may be some differences between the two. Rats are bigger than mice and would need a larger dose of poison to kill them, while mice need less rat poison to die.

Mothballs are great for keeping out certain insects, but do mothballs keep mice away? Find out here.

  1. DCon had it right. That green junk laid in my garage for 6months and nothing would eat it. Finally set some traps and caught 6 mice in one night right next to the un attended green bait. Just when you get a good product the EPA screws it up. I watched mice climb over the bait and go on their marry way. What a joke.
