Richard. Cave hibernating bats establish separate maternal roost sites in the
summer. They will return to their winter roosts and not remain in your siding
over the winter.
If you are serious about doing them no harm as I am sure you are I think you
should get in touch with Bat Conservation intl who can give you advice and
perhaps put you in touch with a local representative who can offer some
assistance.
