Delete session at expire

Hi Guys,

When a user logs in I do a check to see if they have multiple sessions in the browser if yes they get a pop up notifying them they are logged in on more than one device etc...

But the messages pops up most of the time because when a session expires it keeps the session in the table is there a way I can delete the session as soon as it expires?

thanks in advance.

regards,
