You should only be starting them from xmonad as part of DynamicLog, in
which case they go away when the xmonad that started them does.

If you must start things not over a pipe from the startup hook (this is
strongly disrecommended; this is what ~/.xsession is for), you can check
for command line arguments.

    , startupHook = do args <- getArgs
                      guard (null args) $ spawn "xmobar"
