When rodents and other pests enter your dwelling, it may be tempting to rely on anecdotes and evidence given by well-meaning friends or relatives. These solutions are not always effective or humane.
It is possible to kill mice using Coca Cola or other carbonated beverages. Mice have little to no gag reflex and cannot belch or vomit.
Using Coca Cola as a rodenticide is not recommended – the amount needed to kill a mouse varies depending on the mouse's size, age, overall health and individual digestive system. Additionally, this method is not considered humane; it takes a long time for a mouse to die from a buildup of intestinal gas.
Consider other options for clearing up your mouse infestation, including live traps. Speak to a professional exterminator if you feel you cannot safely and humanely rid your home of mice.
