How Does Baking Soda and Peanut Butter Kill Rats?

The lethal mechanism behind this homemade rat poison lies in the chemical reaction between baking soda (sodium bicarbonate) and the rat’s stomach acid. The reaction produces carbon dioxide gas, which rats, unlike many other animals, cannot expel through burping or flatulence.

When a rat consumes a mixture of peanut butter and baking soda, the baking soda interacts with the hydrochloric acid in its stomach. This interaction generates carbon dioxide (CO2) gas. Because rats lack the physiological mechanisms to release this gas, it builds up within their digestive system. This buildup can lead to bloating, internal pressure, and, eventually, organ rupture or fatal blockages. Source: Bugwise Pest Control

Why Use Peanut Butter as Bait?

Peanut butter serves as the perfect attractant in this DIY rat poison for several key reasons:

Irresistible Aroma: Rats possess a highly developed sense of smell, and the potent aroma of peanut butter is incredibly enticing to them.
High Caloric Value: Peanut butter is a calorie-dense food, rich in fats and proteins, making it a highly desirable food source for rodents seeking sustenance.
Sticky Consistency: The sticky texture of peanut butter helps to bind the baking soda, ensuring that the rat consumes a sufficient amount of the lethal ingredient. It also makes it more difficult for the rat to separate the baking soda from the bait.
Palatability: Peanut butter’s taste, fat, and protein make it a very appealing food.

Is This Method Effective and Reliable?

While many anecdotal accounts support the effectiveness of baking soda and peanut butter as rat poison, it’s crucial to acknowledge its limitations. The effectiveness of this method can be inconsistent and is not always guaranteed.

The success rate depends on several factors:

Amount of Baking Soda Ingested: A rat must consume a sufficient quantity of baking soda for the gas buildup to be fatal. If the rat only ingests a small amount, it may experience discomfort but survive.
Individual Rat Physiology: Factors like the rat’s size, age, and overall health can influence its susceptibility to the baking soda.
Presence of Other Food Sources: If readily available alternative food sources are present, rats may be less inclined to consume the baking soda and peanut butter mixture in lethal quantities.
Delayed Action: Unlike commercial rodenticides that act quickly, baking soda can take several days to kill a rat, during which time the rat may continue to cause damage.
