Antifreeze does not harm rats overnight. It may take a few days depending upon the amount of antifreeze they drank. After putting this homemade rat poison out there, some people think that it’s not working because they don’t see any dead bodies the next day.

But it really works. Just it takes some time. But, you should not use antifreeze to get rid of the rodents. And if you have pets or small children, then don’t even think about it.

How Much Antifreeze Is Needed?

Antifreeze for rodents

There is no specific research that gives a clear answer to this question.

According to my experiences, as little as two ounces of antifreeze can make a dog ill, and one teaspoon can murder a cat and two tablespoons of antifreeze are hazardous for a child. So, from this information, we can guess that less than one teaspoon is enough to finish off a rat.

But, it also shows how dangerous antifreeze can be for anyone, whether it’s a pet or a child.

What Other Rodents Can You Use Antifreeze On

Antifreeze substance is poisonous for all small creatures whether they’re mice, rats, squirrels, chipmunks, raccoons, or any other animal.

Antifreeze is also hazardous for pets like dogs & cats. It’s hazardous even for humans also.

Every year, many dogs and cats die due to antifreeze liquid poisoning, which was placed as bait.

That’s why you should not use antifreeze as a rat poison.

What Kind of Antifreeze To Use?

Antifreeze is going to cause a pest the size of a rat to die slowly. The rodent will eventually die and hopefully it will be out of sight and away from your property when that happens.

The active ingredient in antifreeze that harms the rats is known as:

  • Ethylene Glycol

Be extremely careful with Ethylene Glycol because it will kill pets too. The scent is sweet and makes it appealing for a curious wanderer to take a sip. Leaving antifreeze out with Ethylene Glycol will be dangerous in any house with pets.

It will take a few days for a rat to die from antifreeze poisoning. 

Antifreeze Poisoning in Dogs & Cats

According to the Pet Helpline, as little as one teaspoon of antifreeze liquid can be fatal for a cat when ingested, while for a dog it can be one or two tablespoons depending on the size of the dog.

Cats must be treated within 3 hours of poisoning, while dogs must be treated within 8-12 hours of poisoning. If you delay the treatment, it’ll not be effective. Once a cat or dog reaches the stage of kidney failure, the prognosis is poor.

How To Use Antifreeze As Rat Poison?

First, you should not use antifreeze to deal with rat infestation because rat baits work faster than antifreeze. In the below, I have also shared some alternatives to antifreeze, so make sure to check them.

But, still, if you want to use, then these are the steps:

  • Wear gloves before handling antifreeze.
  • Soak some bread or any other food in antifreeze that can absorb some of it.
  • Place the bread where rodents can find them and at the same time, it’s away from the reach of children and pets.
  • It’s better if you cover the antifreeze bait with some cardboard so that rats can find a clear way to the bait. It’ll also give the rat some sense of security so that it can just move to the bait and eat it.
