How to auto-delete a Queue?

[ZedZipDev]

I have N customers, each of them has its own Queue using fanout exchange:
Que-1
Que-2
...
Que-N

Publishers published messages to to fanout exchange, i.e. Publisher->pub msg->(to all Que-1 - Que-N)

Each customer reads its own queue
customer i - reads -Que-i

The question is:

How can I solve this problem: if no customer reads this Que-* in K minutes then this Que should be deleted with messages.
I.e. publishers can publish messages, but if no customer reads it then it should be dropped.
