Rats may be getting more aggressive due to closure of restaurants
Humans are not the only ones who miss dining out.
As restaurants and other businesses have closed during the coronavirus pandemic, rats may become more aggressive as they hunt for new sources of food, the Centers for Disease Control and Prevention warned.
Environmental health and rodent control programs may see an increase in service requests related to “unusual or aggressive” rodent behavior, the agency said on its website on Thursday.
“The rats are not becoming aggressive toward people, but toward each other,” Bobby Corrigan, an urban rodentologist who has both a master’s degree and Ph.D. in rodent pest management, said.“They’re simply turning on each other.”
Corrigan said there are certain colonies of rats in New York that have depended on restaurants’ nightly trash for hundreds of generations, coming out of the sewers and alleys to ravage the bags left on the streets. With the shutdown, all of that went away, leaving rats hungry and desperate.
In New Orleans, hordes of rats took over the streets after people emptied out. Hundreds of thousands of rats in Chicago have started boldly searching for food, traveling farther and during the daytime.
Corrigan said pest control professionals in the city have sent him photos of rodent cannibalization and slaughter.
To keep rodents at bay, the CDC recommended sealing access to homes and businesses, removing debris, keeping garbage in tightly covered bins and removing pet and bird food from yards.
