Bed bugs are exploding in North American cities like Toronto and the city’s environment manager Reg Ayre has an explanation for why. Developing countries used to use DDT to kill the bugs until it was discovered that the toxin was killing bird species. Recent bans on the use of DDT and other effective—but toxic—pesticides have contributed to the spread of bed bugs worldwide, Ayre told the Toronto Sun. A study released earlier this month ranked Toronto the third-most-infested city in North America after Columbus, Ohio and New York City.
