I have been spraying cotoneaster hedges for the past week for oystershell scale. Here are my findings: 1) Oystershell scale has infested Calgary from the core to the suburbs. Every hedge I have encountered so far has been infested to some degree. 2) I see the highest populations of insects on hedges that have never [..]
