New York City has a notorious rat problem, with millions of rodents infesting the streets, subways, parks, and buildings. The city has tried various methods to control the rat population, such as poison, traps, dry ice, and even dogs, but none of them have been very effective.
Recently, the city has deployed a new weapon that has proven to be wildly successful in killing rats. The weapon is carbon monoxide, a colorless, odorless, and lethal gas that suffocates the rats in their burrows. The method involves pumping carbon monoxide into rat burrows that are found in sidewalk tree beds, using a device called the Rodenator. The device also creates a small explosion that collapses the burrow, preventing other rats from moving in.
