The Oregon Department of Agriculture confirmed today that an application of the insecticide Safari is directly responsible for thousands of dead bumblebees in a Wilsonville Target parking lot.
The agency has sent a crew to shroud 55 European linden trees with shade cloth to prevent more bees from dying.
The linden trees were sprayed with Safari on Saturday by a landscaping company. The name of the company has not been released. ODA collected samples of the bees and foliage from the Target parking lot and tested them in a lab to determine whether the pesticide had caused the bee deaths.
The agency is continuing its investigation to determine whether the pesticide application violated state and federal regulations.
