US cities 'will soon be in dire need of rat control'
An expert in the US has warned that the country's cities will soon face an invasion of rats, leading to an increased need for rat control measures.
Dale Kaukeinen, a small mammal biologist, warned in a recent study that urban areas of the country are on the verge of a rapid rise in rodent populations, reports ABC News.
He said this imminent need for more pest control measures can be attributed to the downturn in the economy and the growing desire for green spaces in US cities.
"The problem of rats is just a symptom of a declining and weakening infrastructure, and it's one of the more visible symptoms of depressed cities struggling to face their problems," Mr Kaukeinen commented.
He added that as more green spaces are incorporated into the design of cities, there is more space for rats to live.
Last month Chicago resident Anne Moore said in an article for the Chicago Tribue that she had to take a variety of pest control measure to get rid of rats in her garden, including blocking up small holes and laying traps.
