You can contact the agent that listed the home to request that they be removed but I suggest that you contact Trulia as they can probably remove them more quickly.
Here is Trulia's contact information:
Call: 888-466-3501 M-F from 7:00 a.m. to 4:00 p.m PST or
Email: http://www.trulia.com/help/ask (be sure to include the entire address of your home when contacting them).
