In subform of a MS Access form, how to hide/show the vertical scroll bars as needed?

I have a subform in an MS Access form which is not hiding/showing the vertical scroll bars as needed. In the example picture, the vertical scroll bar is showing even though there aren't enough records to warrant vertical scrolling. How do I get the scroll bars to show only when they are needed? Do I need to add an if-then condition to the on_load event? or is there an easier option?

You may find something on these lines suits:

 If Me.Recordset.RecordCount > 10 Then
      Me.ScrollBars = 2 ''Vertical only
 Else
      Me.Scrollbars = 0 ''Neither
 End If
