Show membership Packages only

Hi,
I have set up a number of membership packages that all have the same listing package, the only difference between the membership packages being how many listings they can post – e.g. 1 only, a few or many.
I would now like visitors to see only the different types of membership package available, but on the “Listing page” it shows the listing packages and the membership packages.
How can I show only the membership packages available (and hide the listing packages)?
