MSMQ - Can we delete outgoing message queues? Lifecycle?

Hi,
We want to make disappear the outgoing message queues to be sure that our app wouldn't use them anymore. If Outgoing Message Queues are temporary, when does it disappear from compmgmt.msc when they are suspended and cleared, and the application only uses local message queues afterword? What is their lifecycle? Is there a way to delete them?
Best Regards,

These temporary queues are managed by the MSMQ system. AFAIK, they are only used when the machine has no network connection and MSMQ is responsible for re-establishing the connection and the lifetime of the temp queues.

I don't believe an application has any control of how MSMQ goes about doing its job internally.
