Best way for Google and Bing not to crawl my /en default english pages

[Shawn124]

Hi Guys,

I just transferred my old site to a new one and now have sub folder TLD's.  My default pages from the front end and sitemap don't show /en after www.mysite.com.  The only translation i have is in spanish where Google will crawl www.mysite.com/es (spanish).

1. On the SERPS of Google and Bing, every url that is crawled, shows the extra "/en" in my TLD.  I find that very weird considering there is no physical /en in my urls.  When i select the link it automatically redirects to it's default and natural page (no /en).  All canonical tags do not show /en either, ONLY the SERPS. Should robots.txt be updated to "disallow /en"?

2. While i did a site transfer, we have altered some of the category url's in our domain.  So we've had a lot of 301 redirects, but while searching specific keywords in the SERPS, the #1 ranked url shows up as our old url that redirects to a 404 page, and our newly created url shows up as #2 that goes to the correct page.  Is there anyway to tell Google to stop showing our old url's in the SERP's?  And would the "Fetch as Google" option in GWT be a great option to upload all of my url's so Google bots can crawl the right pages only?

Direct Message me if you want real examples.  THank you so much!
