Warmer than usual winter temperatures have created a breeding ground for rodents in many Swiss cities
Swiss cities, experts say there has been a notable rise in the last few months. The proliferation could be the result of global warming. According to exterminator Simon Gross from Bern, “the warmer winter makes it easier for older and sick rats to survive.” The milder temperatures also accelerate reproduction. Rats can have up to six litters a year, with an average of eight babies, which reach sexual maturity in two months. “If we don’t intervene, their numbers will explode.”
