Combining sodium bicarbonate with palatable substances is sometimes suggested as a method of pest control targeting rodents. The theory posits that ingestion of the mixture leads to internal gas production, which rodents cannot expel, potentially causing fatal complications. Common components considered for blending with the sodium bicarbonate include grains, sugars, or fats to entice consumption.
The purported advantage of this approach lies in its accessibility and perceived lower toxicity compared to traditional rodenticides. However, its effectiveness is debated, and its reliability as a primary means of rodent extermination is questionable. Historically, various home remedies have been employed for pest management, often with limited scientific backing.
