Welcome to our best rat poison review. Rat infestations in towns and cities are commonplace and cause many problems for households and businesses every year. Rats are a big problem because they carry Weil’s disease passed to humans through their urine. The symptoms are similar to flu and can last for five days but, in very severe cases, can cause organ failure and death due to heart, liver, or respiratory failure.

These infestations are a health hazard, but they can cause a lot of damage to properties which will cost a lot to repair. Quickly dealing with a rat infestation is crucial. There are many ways to deal with a rat problem, and one of the best is to use a rodent bait poison. However, there are so many to choose from, and making the right choice for you can be challenging. For instance, what’s safe if you have children or pets? What works best indoors or outdoors? How much do you need for a lethal dose, and do you need a bait station?

We’ve tested a whole range of products and selected our Best Overall and Best Value picks, so you can buy with greater confidence no matter what situation you are experiencing.

Rat Poison Buyers Guide:

Is Rat Poison safe to use?

You must always read the product ingredients and user instructions very carefully. Remember, you are putting poison down, and a bit like weed killer can cause unintentional damage to other things. If you have young kids, cats, or dogs in the area where you are leaving the rat poison, then it’s best to contact a professional pest controller. There are also some non-toxic options available, but the effectiveness of these is sketchy.

Always follow safety precautions.

The manufacturer of each rat poison will specify the same safety precautions to follow when using their product. They will be printed on the packaging and their website and are compulsory US Environmental Protection Agency regulations.

If a product does not have this, then they are not to be used under ANY CIRCUMSTANCES. We advise you to follow these implicitly. There are some products available that are designed to kill only rats. However, the vast majority contain lethal doses of toxins that affect other animals.  

Please also consider the impact on the environment. Once a rat dies, it becomes food for other species, such as birds. They will likely become infected and die from the poison, and this can cause a significant ecological impact. We advise you to wear gloves when handling any product and to wash your hands with warm, soapy water immediately afterward.

What is the right dose?

You will need to establish what type of infestation you have. Is it mice or rats? If it’s mice, then use a poison only for mice as the dose to kill them will be different. It’s also tough to spot them! You most likely hear them or see damage around your home. An excellent way to establish the species is to look for their droppings. Rats will leave larger droppings, and so that’ll give you a steer as to what poison to buy.

How does rat poison work?

Rat poisons work differently depending on the active ingredient and dose. A famous toxin is Bromethalin, and your product should contain around 0.01%. This causes neurological dysfunction and paralyzes, leading to death as their whole body shuts down.

Zinc Phosphide is also a popular active ingredient and works by producing a very toxic gas when eaten, as the animals’ stomach acid reacts with it. This stops the cells from producing energy, leading to death. Anticoagulants cause a rodent to bleed internally and therefore die. However, it is a slow process and requires a high dose.

A non-toxic poison is a calcium releaser. Too much calcium in rodent’s blood causes organ failure and, ultimately, death. The safest and most popular choice is vitamin D3 because it does not pose a secondary risk to other animals.

What other ingredients are in rat poison?

Rat poison comes in various forms, from pellets to wax bars. They all contain a type of Rodenticide and an ingredient to make them appealing to rats.  

How long will it take to kill rats?

Most rat poisons specify death within five days from consumption. However, it all depends on how much the rat eats. Rats store their food so you may see your poison disappear over a few days, and this can lead to frustration as they’re still alive, but a few days later, you will cull them as they then eat it.

Removing any other food source and spreading the poison around to the areas of an infestation can speed up the process. Wherever you choose to place the poison, ensure you stick to it as rodents won’t eat something they are unfamiliar with!

What effect will it have on the environment?

While you can solve your infestation problem quickly by using rat poison, you could also inadvertently cause a much larger ecological problem. It will be essential to dispose of dead rats as soon as possible to prevent other species from eating their dead bodies. Should they do, they are likely to be poisoned and die themselves. Birds, cats, and dogs are all at risk here and so following the manufacturer’s instructions closely will help prevent a negative knock-on effect.

How do you make homemade rat killer?

Put on disposable gloves to avoid skin irritation. Start by adding 1 cup of boric acid into a bowl, then start adding chicken broth, about half teaspoon at a time, and stirring very well after each addition until the paste is thick enough that it’s no longer easily mixed but not so thin as to run off your spoon or spatula with too much ease – you want something in between these extremes when making this quick-to-make rodent killer bait mix! 

The odor from the mixture will attract rats which will eventually die once they consume this lethal concoction. 

Roll the paste into balls about the size of marbles. Place two or three of these bait balls on jar lids or other small containers; this will ensure you can quickly relocate them if need be. If there are droppings somewhere close by, like under a sink, place one near it, so rats have an easy time returning for more food next time!

Does baking soda kill rats? 

Baking soda is a great natural ingredient that can be used to make your rat poison. Combined with other potent ingredients, it will allow you to kill rats without the use of harsh chemicals or toxins! 

The baking soda reacts with the rat’s stomach acid to produce a carbon dioxide gas. This causes an internal blockage or rupture in the rat, and death can occur within six hours due to this buildup.
