New York State Department of Health workers use dry ice to put it in rat holes.

The ambient air temperature ensures that carbon dioxide turns into a gaseous form and suffocates rats that usually sleep at this time of day.

Usually from 90 to 100 percent of rodents perish.

“This method is very effective mainly in green spaces, parks,” says Simeone, director of pest control for the New York City Department of Health.

Rats settled in New York in the middle of the 18 century and became the source of numerous diseases.

The 2014 study of the year, published by PhD candidate at Columbia University, counted about two million rats in New York City, where more than 8,5 million people live.

Most often, rats are found on the street or in the subway. Recall the video posted on YouTube in 2015 the year in which the rat dragged a slice of pizza on the subway stairs.

In 2012, John Stellberger was the first to use dry ice against rats in the United States, based on the idea of ​​one of his employees.

At the beginning of this year, after several months of testing, New York officially adopted the dry ice technique, joining Boston, Chicago and Washington.

Dry ice is used only in open spaces, including parks and green areas. In addition to its effectiveness, dry ice does not pose a danger to wildlife in parks and public gardens, unlike rodenticides, which were previously the only weapons used against rats.
