New York is waging a war on multiple fronts to combat the near ubiquitous rats that plague city streets and the subways, leaving some residents afraid to let their children walk on sidewalks.
Faced with an overwhelming and ever-growing problem, officials have moved beyond gassing burrows to suffocate rodents, and are now using high-tech mapping tools to try and sterilize the population.
Alongside targeted interventions, officials are mounting an effort to educate the public about the need to avoid leaving behind food waste that feeds and sustains the rat population.

Caroline Bragdon, director of neighborhood interventions for Pest Control Services within New York City Department of Health, said that the lack of food “stresses” rats and other vermin.
“Perhaps this forces them to go further in search of food, but perhaps they simply have fewer offspring,” she said.
“That’s usually what we’re seeing. Fewer rats over time. Less breeding leads to less rat activity,” Bragdon added.
The city is testing out an arsenal of different tools in the Harlem neighborhood, aiming to find new products and methods to tackle the rats. For large, densely populated cities such as New York — with its 8.5 million inhabitants — food sources for the rodents are bountiful, whether it is on sidewalks, in overflowing trash bins, or in parks.
“Lately, I haven’t felt that I have to run in between the mounds of trash to run away from rats, because they have those new [sealed trash] containers,” said Harlem resident Karen Del Aguila, 50.
Rats, which survive on practically the same diet as humans, can flourish even on items discarded as trash — such as soda cans thrown into recycling bins, or crumbs given to pigeons, Bragdon said.
A rat needs 28g of food per day to sustain itself, and it can have up to 12 offspring per litter. During its short life of less than a year, it can have five to seven litters.
The best way to counter the scourge of rats is to “remove their food source... So, make it harder for them, then they’re going to have to travel further to try and find something,” said Alexa Albert, a supervisor for the city’s pest control service.
She swiped her screen to show the street-level data logged on a rat tracker app used by those involved in the crusade against rodent infestation.
The city health department’s 70 inspectors use the mobile app to detect, report and monitor rodent activity — as well as plot abatement tactics.
Inspectors go door to door asking businesses and residents to clean buildings, stores and sidewalks.
Authorities also now offer training on how to combat rats, taken by thousands of residents and building managers. In October 2022, New York City vaunted a “trash revolution,” aimed at installing sealed containers to allow the removal of black bags of organic waste from sidewalks after rats surged during the COVID-19 pandemic.
Pre-pandemic, their population had been cut by as much as 90 percent in some areas.
“So, we know it can be done,” said Bragdon, who added that she hoped this year would be a “turnaround year.”
Local resident Jessica Sanchez said she had observed much fewer rats in her neighborhood.
“Not a long time ago, when you went to put out the trash, five of them came out,” she said. “I was even afraid to put my son on the floor.”
The rat warriors are seeking to learn the rodents’ dietary habits throughout the year by using samples of different food types to identify what bait they are most likely to take.
Last year, complaints about rat activity dropped 25 percent compared with the year before, according to official data.
However, so far, only Manhattan’s Chinatown has managed to bring the rat population under control.
Nauru has started selling passports to fund climate action, but is so far struggling to attract new citizens to the low-lying, largely barren island in the Pacific Ocean. Nauru, one of the world’s smallest nations, has a novel plan to fund its fight against climate change by selling so-called “Golden Passports.” Selling for US$105,000 each, Nauru plans to drum up more than US$5 million in the first year of the “climate resilience citizenship” program. Almost six months after the scheme opened in February, Nauru has so far approved just six applications — covering two families and four individuals. Despite the slow start —
YELLOW SHIRTS: Many protesters were associated with pro-royalist groups that had previously supported the ouster of Paetongtarn’s father, Thaksin, in 2006 Protesters rallied on Saturday in the Thai capital to demand the resignation of court-suspended Thai Prime Minister Paetongtarn Shinawatra and in support of the armed forces following a violent border dispute with Cambodia that killed more than three dozen people and displaced more than 260,000. Gathered at Bangkok’s Victory Monument despite soaring temperatures, many sang patriotic songs and listened to speeches denouncing Paetongtarn and her father, former Thai prime minister Thaksin Shinawatra, and voiced their backing of the country’s army, which has always retained substantial power in the Southeast Asian country. Police said there were about 2,000 protesters by mid-afternoon, although
MOGAMI-CLASS FRIGATES: The deal is a ‘big step toward elevating national security cooperation with Australia, which is our special strategic partner,’ a Japanese official said Australia is to upgrade its navy with 11 Mogami-class frigates built by Japan’s Mitsubishi Heavy Industries, Australian Minister for Defence Richard Marles said yesterday. Billed as Japan’s biggest defense export deal since World War II, Australia is to pay US$6 billion over the next 10 years to acquire the fleet of stealth frigates. Australia is in the midst of a major military restructure, bolstering its navy with long-range firepower in an effort to deter China. It is striving to expand its fleet of major warships from 11 to 26 over the next decade. “This is clearly the biggest defense-industry agreement that has ever
DEADLY TASTE TEST: Erin Patterson tried to kill her estranged husband three times, police said in one of the major claims not heard during her initial trial Australia’s recently convicted mushroom murderer also tried to poison her husband with bolognese pasta and chicken korma curry, according to testimony aired yesterday after a suppression order lapsed. Home cook Erin Patterson was found guilty last month of murdering her husband’s parents and elderly aunt in 2023, lacing their beef Wellington lunch with lethal death cap mushrooms. A series of potentially damning allegations about Patterson’s behavior in the lead-up to the meal were withheld from the jury to give the mother-of-two a fair trial. Supreme Court Justice Christopher Beale yesterday rejected an application to keep these allegations secret. Patterson tried to kill her
