I was just out in my garden battening down the hatches for tonight's wind
storm, when I saw a vine weevil on an upturned bucket, nowhere near any
plants. However, I know that where there's one vine weevil there are
probably zillions.

Is it too late in the year now to be applying either chemical or biological
control? Should I wait until March, or are vine weevil active all year?

Thanks
