Where do u live? If your in america they need a warrant to flir your house. Just dont do anything stupid or careless and give them a real reason to come over. if they do do that DO NOT let them trick you into letting them search the house or even come inside the house. You have a right to refuse a search, exericise that right of yours. Say something like "im too busy" or "gotta go somewhere" if/when they ask you why you refuse it, also dont let them get you with the "We just want to do a quick search and we'll be out of your hair right after that." either.
