How Dry Ice Effectively Manages Rodent Infestations

Dry ice is a solid form of carbon dioxide that, when used in rodent control, offers a unique and effective method of managing rodent populations, particularly mice. This technique, known as carbon dioxide fumigation, leverages the properties of dry ice to create an uninhabitable environment for rodents, thus controlling infestations efficiently.

When dry ice sublimates, it transforms directly from a solid to a gas at -78.5 °C, releasing a dense cloud of carbon dioxide. In the context of mouse extermination, this gas plays a critical role. By placing dry ice pellets into the burrows and nesting areas commonly inhabited by mice, the sublimating carbon dioxide replaces the oxygen in these confined spaces. Since mice are mammals that require oxygen to survive, the displacement of oxygen with carbon dioxide leads to an anoxic, or oxygen-deprived, environment. This method induces a state of hypoxia in the rodents, leading to their humane extermination.

The effectiveness of dry ice in rodent mitigation lies in its ability to penetrate deep into the rodents’ nests, a task that is often challenging with traditional traps and poisons. This makes dry ice particularly beneficial in managing rodent populations in areas that are otherwise hard to reach, such as subterranean burrow systems, wall voids, and other secluded spaces.

Moreover, dry ice offers a significant advantage in residential and commercial rodent control due to its minimal impact on the environment. Unlike many rodenticides, dry ice leaves no harmful chemical residues, making it a safer choice in environments where chemical exposure is a concern. This characteristic of dry ice aligns well with environmentally conscious pest management practices.

Additionally, the use of dry ice in controlling mice minimizes the risk of secondary poisoning often associated with conventional rodenticides. Non-target animals, pets, and even humans are less likely to face accidental harm, as the method does not rely on toxic substances that can be ingested or otherwise transferred.

The use of dry ice in rodent control offers a safe, humane, and effective solution for managing mouse infestations, especially in challenging or sensitive environments. Its ability to create an anoxic condition in targeted areas, combined with its eco-friendly properties, positions dry ice as a preferred method in modern pest management strategies.

Significant success was observed in major U.S. cities like Boston, where the use of dry ice in 2016 led to a dramatic reduction in rat burrows. For instance, Columbus Park saw a decrease from 60 to just two rat burrows, demonstrating the efficacy of this approach​​​​.
