deleting files left over from old cpanel accounts

When I delete a cpanel account in whm, some files are left in the apache/domlogs directory, for instance domain.com domain.com-bytes_log and domain.com-bytes_log.offset files.

My questions are -

Can I safely delete these files?

Are they simply left overs that cpanel has failed to remove?

Do you know of any other areas that may contain files that also need removing that are left over by cpanel?

Thanks for any help.

Cheers

chmod
