Barely two weeks after 25,000 bees were found dead in a parking lot in Oregon, another round of bee devastation has been reported. This time, the mass die-off was far worse. More than 37 million honeybees were found dead in Elmwood, Ontario, according to beekeeper Dave Schuit, who lost the bees from 600 hives in June. He and many others are pointing to insecticides called neonicotinoids, used in planting corn and some other crops. “Once the corn started to get planted [in Elmwood] our bees died by the millions,” Schuit said. After a record-breaking loss of honeybees in the U.K., the European Union banned several pesticides in May, including neonicotinoid pesticides.
