How to remove a ROVING BUG from my Iphone5?

My Iphone 5 has the roving bug that activates the microphone on the phone enabling someone to listen to our coversation around the phone, even when it is not in use.

I no that it is "bugged" as the battery keep draining Really quickly and i used a bug detector and the phone keeps sending of signals even when it is not in use.

I've found load of sites that show you how to put the bug on a phone but none to show you how to take it off.

Any one who is tech savvy please can you reply.

Maybe you just need a new battery, smartphones give off signals all the time as it communicates with the web doing updates etc
