Not that you were worried about how rats got along when Covid closed restaurants, but the Post has a story on the reasons rats never run out of options — and what you can do about it.

Few of us are fans of cockroaches, rats, or other durable scourges of the human community, and yet perhaps we owe them grudging respect for an uncanny ability to survive no matter what.

Dana Hedgpeth, Tara McCarty and Joe Fox reported at the Washington Post on how the rats of the nation’s capital essentially laughed off Covid and its effect on easy food.

“Rats are a fixture of urban life,” they write, “but early in the pandemic, their populations in urban cores shrank as restaurants, parks and offices shut down — and their access to trash did too. But many adapted, desperate to survive. They ate off the bottom of restaurant doors in search of food … and a large number, to residents’ frustration, migrated.

“ ‘They’ve gotten into places where there were no rats, and now people are calling and saying, “I’ve lived here for 20 years and never seen a rat until now,” ‘ said Gerard Brown, who oversees rodent control at D.C. Health. …

“ ‘There’s a rat resurgence,’ said Bobby Corrigan, among the world’s best-known rodentologists. ‘They may be bouncing back with larger families in both the urban core and in the more residential neighborhoods of D.C.’

“Known formally as Rattus norvegicus, the brown rat is the species found in D.C.’s streets and many major cities. Most people agree that rats are gross and that they can cause health problems and property damage. …

“Orkin, one of the biggest pest control management companies in the country, ranked D.C. fourth in its annual ranking of the top 50 ‘rattiest cities,’ placing it behind Chicago, New York and Los Angeles.

“In D.C., reports of rat sightings are up: The city service hotline has fielded more than 13,300 complaints in the 2022 fiscal year — compared with roughly 6,200 in the 2018 fiscal year, according to the city’s health department. Despite this increase, health officials said they haven’t seen a surge in rat-related illnesses.

“More complaints mean more work for rat catchers: Before the pandemic, Scott Mullaney and his wife, Angie Mullaney — who run a business that uses Patterdale terriers to catch and kill rats — used to average about 25 rats at a job site. Now as people return to life and business as usual, their dogs catch closer to 60 per site some nights. …

“To survive as a rat, you must be clever. Think you have what it takes to scavenge for something to eat or find a safe place to sleep? We built a video game to show you how rats live — and thrive — in the city. You’ll play as Cheddar, a D.C. rat whose name was picked by readers. Try your hand (or paw) at survival by finding food, water and a spot to nest in different environments throughout this story. …

“Rats are smart. They know that they can reliably get food and water from fountains, birdbaths, pet bowls, dripping sprinklers and trash cans and that some decked-out yards offer bigger bounties — including pet poop. …

“Redevelopment creates prime real estate for rats: Home and apartment renovations leave stray pipes that can provide a path from the sewer into buildings and into the walls.

“Jake Rosen was living in Petworth when he repeatedly heard rats inside the walls of his home. He believes they worked their way in through gaps in the concrete under a porch when construction started on a nearby house, where he thinks the rats were probably nesting. It takes only one house on a block to draw rats in, and then suddenly they’re everyone’s problem. …

“Tucked away in an alley off Ward Court NW, in Dupont Circle, rats were scrounging for their meals among a cluster of trash cans and dumpsters by several apartment buildings. They fled pedestrians and their dogs, sprinting under bushes and other plants.

“Michael Beidler has lived on the block for more than three decades and sees rats scavenge in trash bags left outside, often on the ground spilling over from dumpsters. For rats, it’s the perfect setup. They get their food from the dumpsters and then burrow in his yard. Beidler spent about $3,000 on rat traps and had a contractor pour as much concrete as he could to cover up his garden to try to keep out the rats. …

“Apartment buildings offer rats a trash feast. From a dumpster, they can jump onto and scurry up the outside of a trash chute, squeezing into holes behind the brackets to get inside. They also get inside trash rooms through open doors or gnaw through the mortar between bricks in a foundation.

“A rat can fit its head through a hole about the size of a marble. Its rib cage has a ‘collapsibility function,’ and once it gets its head in, a rat uses its vibrissae — long whiskers on its nose and face — to feel to make sure it’s safe. Then it does what Corrigan calls ‘squeeze-wiggle gymnastics’ to get the rest of its body through. …

“Rats will never be eliminated — and play an important role in the ecosystem as food for foxes, coyotes, snakes, hawks and owls. Yet for the D.C. rat-control crew, the end game is to reduce their population in areas where humans live, work and play.” That’s the bottom line.

The Post, here. has a list of what to do if you have rats. And in the interest of helping you outsmart them, the newspaper also offers a game that helps you think like a rat. Check it out.
