Primary Sidebar Widget Settings

Hello, Sorry i'm very new at this. I couldn't figure out how to disable the primary sidebar. When i took out all of the options in it there was still an area for the sidebar and it defaulted to a few options. To get around this I put a nice map picture there which links to a store locator. Now the problem is that the primary sidebar is active on every page. At this point i like the store locator and would like to know if the primary sidebar can be disabled on all pages except the home page? Thanks B
