Bad news: Contact Trulia
Trulia uses every bit of information it can to help consumers find, compare, and research homes. If your concern is about privacy you'll also need to contact the other big name "real estate syndication sites". You can also request that Google, Yahoo, Bing and the other big search engines delete your name, your address and your phone number from their public directories. If your home shows up on Trulia it probably shows up on at least 23 other real estate websites.
The root of the problem will still be in the public records including tax records. Removal from public records will prove more difficult unless you're a first responder including Police, Firefighter, EMT, or some .gov employment that would allow the exclusion.
If the concern is privacy you should look into buying your next home with a Land Trust or Trust.
