Nothing is as disturbing and frightening as discovering that mice, rodents, or small critters have invaded your precious home. If this is one of your problems at your home, you are not alone. Studies have shown that 37% of homeowners in the United States have rodent problems. But how can you treat the mice problems at home without poison that your pets or children can accidentally consume? What is a natural way to get rid of them? Does baking soda kill mice?

Fortunately, many household remedies exist to get rid of these little creatures. And one of them is baking soda. The bicarbonate in baking soda will react with the stomach acids of mice. A gas known as carbon dioxide will build up in their digestive system, which will eventually cause damage or rupture to their body.

Now that you have the answer to “Does Baking Soda Kill Mice?” You might want to know how to use this household staple to resolve mice infestation at home. Below, we will discuss this.

How Does Baking Soda Kill Mice?

Baking soda or sodium bicarbonate is a helpful household ingredient. This white powder is reliable for many household needs, from cooking to cleaning to setting traps for mice. However, its efficiency as a mouse killer depends on the chemical reaction it creates.

Baking soda is toxic to mice and can kill them in your house. Baking soda is used to expand and soften baked goods and can help the upset stomachs of humans. This chemical reaction happens when carbon dioxide or gas is released.

However, the carbon dioxide created by baking soda is poisonous to mice. Unlike humans, mice don’t know how to pass gas. When these tiny creatures consume baking soda, they eventually die in agony. Their little digestive system can’t digest this ingredient – it presses their organs until they die.

Should You Use Baking Soda to Kill Mice?

Baking soda can indeed kill mice. But the question is – is it the method you should use to solve rodent problems in the house? Well, we have two answers to this question. 

First, baking soda as a pest control can seem inhumane. After all, the gas buildup in their stomachs is painful for them. It will also take time before mice will die; thus, it will be a painful death for these tiny creatures. But if you don’t care about this, then there’s no reason you should not use baking soda to kill mice.

Second and lastly, baking soda is affordable, and it might be readily available in your home. It is also non-toxic for people in the house, unlike chemical-based pest control products, which may harm your family, especially kids and pets.

How Long Does It Take to Kill Mice with Baking Soda?

If you expect mice to die immediately after consuming baking soda, consider another alternative. Unfortunately, eliminating rodents in the house will take days or even weeks. And these pests might not eat enough baking soda to make them die.

If you have patience, though, there’s no reason to use other alternatives to baking soda. But if you want a quicker and less painful death, you might want to use other methods of killing mice.  

What If Baking Soda Doesn’t Work in Killing Mice?

If baking soda doesn’t work at first to kill mice, you might want to trick them to kill them. Mice need to consume a lot of baking soda for them to die. 

Also, mice are wise and tend to avoid things that seem poisonous to them. Hence, mix baking soda with other ingredients, such as sugar, to entice them to eat it.

Are you worried that killing mice with baking soda can make a mess? You don’t need to overthink it because baking soda will not make mice explode. 

The gas created in their stomach can only cause internal blockage and then death. Baking soda is not like a firework that can make mice explode.
