Two more mass bee die-offs have been reported in northwest Oregon.
A beekeeper’s entire colony has died suddenly in the Sandy area. It’s the fourth unexplained hive die-off in Clackamas County in less than a week.
And for the second time in a week – this time in Beaverton –bees were found dead under flowering linden trees.
Linden trees sprayed with a class of pesticides called neonicotinoids can harm bees if sprayed improperly.
“It feels like the beginning of summer is now marred by an onslaught of bee kills. It’s very concerning,” said Aimee Code, pesticide program coordinator for the Xerces Society, a Portland-based insect conservation group.
