There is a small trick to land all this traffic to your home page. You need to add a location of your home page for example "index.html" or "nodeID" on 404 error page. And all of the traffic will be directed to home page.

Later you can thoroughly check sitemap and add rel="nofollow".

Hope thi will solve the above mentioned problem for you.
