Although many love having rats as pets, as unwanted guests in your home, they can cause damage and health issues. Consequently, people turn to solutions to rid their space of these creatures. One popular method for getting rid of rats is rodenticides or rat traps. However, some people prefer not to use rodenticides or traps as they may contain harsh chemicals, harm their animals or children, or can result in a slow death for the rat. Because of this, many people search for home remedies to kill rats with baking soda and others. But does killing rats with baking soda work? Even if it does, should you use this method?

Does Baking Soda Kill Rats?

People believe baking soda kills rats because rats cannot burp or pass gas. So, after ingesting baking soda, this product reacts with the acids in the rat’s stomach and creates carbon dioxide. This carbon dioxide then builds within the rat and causes a rupture or blockage that eventually kills the rat. This method may work, but there is no guarantee that it will be effective and is not humane.

Firstly, a rat would have to ingest two to three grams of baking soda to die. The rat would also have to consume it in one go, which is unlikely as baking soda is not one of the rat’s favorite foods and two to three grams is a lot to eat all at once. Secondly, the rat may be immune to baking soda. Rats have a robust immune system and may develop immunity or resistance to baking soda and other poisons.

Should You Use Baking Soda To Kill Rats?

The simple answer is no. This form of pest control is inhumane and would likely cause more problems for you. As the carbon dioxide builds up inside the rat’s stomach, it will experience pain and discomfort. And even though it will take time for a blockage to form or for the rat’s stomach to rupture, the rat will die a slow and painful death. Many other forms of pest control are effective, humane, do not involve pain, and are safe to use around pets and family members.

A sick rat will also likely look for a place to hide while they recover or in their last few days of life. If you suspect rats in your home, they will know which parts have dark, quiet spaces. If they become sick, they will likely seek out these spaces and end up dying there. Having a decaying rat carcass in a hard-to-reach area, like between the walls, under the porch, or in the ceiling, would be inconvenient and unsafe for you and your family. A decaying rat carcass would also attract other pests, making your life even more unpleasant.

Here are some alternatives…

Using Rat Traps

Instead of using unreliable home remedies like baking soda to kill rats or forms of pest control that are inhumane, you could invest in rat traps. There is a wide range of rat traps, some of which are excellent for catch and release and others that kill the rat quickly and efficiently.

Scents To Deter Rats

Once you have control of the rat problem, you can experiment with some trusty home remedies to keep rats away. And because rats have a well-developed sense of smell, strong odors are perfect for deterring them from living in your space. This ability can work in your favor as using scents is a more natural form of pest control and is effective if you situate potent odors in the right places.

To understand where to put strong smells, you should learn how to identify weak spots where rats can gain entry to your home and which species want to share your space. For example, the Norway rat prefers to build nests on the ground or below porches, while the roof rat prefers to build nests in high areas. Consequently, the location of the potential nest is where you should focus on scent placement. So, rather than trying to use baking soda to kill rats, you can experiment with these natural deterrents:

Peppermint

Peppermint has an intense aroma and triggers the rat’s fear sense. You could spray a mixture of peppermint oil and water in the area.

Best Indoor/Outdoor Formula
Natural Armor Animal & Rodent Repellent Spray
  • Ready to use
  • Lasts up to 90 days
  • All ingredients are natural
  • Can be used indoors and outdoors
Check Amazon

Garlic and onion

There are compounds in garlic and onion that trigger the rat’s sense of fear. These also repel deer and raccoons. You could place garlic cloves or onion slices in and around the house or boil garlic and onions in water to create a spray.

Ammonia

Ammonia is a standard cleaning agent and can be used to discourage rats. For example, you can soak cotton balls or rags in ammonia or spray ammonia where you think rats live.
