Metaphorical Washington ‘swamp’ overrun by actual vermin
WASHINGTON—Andre Pittman and Gregory Cornes are on a mission to rid Washington of opportunistic vermin.
But their target isn’t corrupt officials or shady political fixers; it’s Rattus Norvegicus, the common Norway rat.
The nation’s capital is facing a spiraling rat infestation, fueled by mild winters and a human population boom. Washington’s government is struggling to keep pace, with the pest control department fielding a record number of calls.
On one recent day, Pittman and Cornes, both veteran Health Department employees, are working within sight of the Capitol, shoveling dry ice pellets into suspected rat burrow entrances. On another, they’re summoned about six blocks north of the White House, at 16th Street and M, where residents have complained of an outbreak.
“Rats adapt to everything. They can be like geniuses,” Pittman said.
On the grounds of a church, Cornes and Pittman poke around, expertly spotting telltale holes and matted dirt trails that signal rat burrows. Cornes uses an instrument like an extralong Super Soaker to inject poison into the hole, while Pittman watches to see if the white powder puffs up from other holes and then shovels dirt to block those exits.
At the office building next door, the crew receives a hearty welcome from the security guard.
“The rats would scurry over employees’ feet as they left the building after sunset,” says the guard, who asked that his name not be published so as not to embarrass his employer. “We finally moved all garbage cans away from the door because that’s where they would feed and party.”
Cornes assures him, “We’re winning.”
The numbers don’t exactly back up Cornes’ confidence. The pest control company Orkin ranks Washington as America’s fourth “Rattiest City,” based on the number of new service calls per year. That’s up one spot from the previous year and just behind Los Angeles and New York; Chicago has been ranked No. 1 for four consecutive years.
While Washington doesn’t boast New York’s famous subway monsters, anecdotal evidence is piling up that the rodents are on the march. In September, a viral video showed security camera footage of a rat pulling a fire alarm, forcing the evacuation of an apartment building.
Gerard Brown, head of Washington’s rodent control department, says a string of gentle winters has enabled the rodents to breed constantly. The harsh winters don’t necessarily kill off the rats. Most Norway rats live only about eight months, and they stay warm by burrowing underground or chewing their way into basements. But an extended freeze would choke off their food supply, which limits the rodents’ prodigious breeding. A mature female rat can give birth to one litter per month, with an average of 10 babies per litter.
Washington is also in the midst of a gentrification-fueled economic and population boom. The district’s population just passed 700,000—more than Vermont and Wyoming. Brown said the number of restaurants, bars and coffee shops has increased 25 percent in two years.
“More people with more money means more restaurants, which means more garbage, which means more rat food,” Brown said.
In several ways, Washington is perfectly suited for the critters. It is filled with green space, from the National Mall to the many signature traffic circles; Dupont Circle is apparently a hot spot.
Rats also covet the waterfront, and part of Washington’s gentrification boom has focused on the Navy Yards or the new Wharf Marina—presenting the ultimate rodent attraction of a flourishing waterfront restaurant scene.
Mayor Muriel Bowser has allocated an extra $900,000 to boost rodent control efforts and increase staffing. The government is also offering financial assistance and incentives for restaurants to buy minitrash compactors that fit in urban alleyways and limit the rats’ access to food.
