Are Termite Inspections a good practice

[Lee Perry]

I have heard several different takes on this so I want to throw it out there.  Is it good practice to call a termite company to come out and check even though there has never been termites or any signs of them.  I have been told that they will always use words like there could be termites or some signs but no proof in order to get business.  Once they treat you have to pay hundreds of dollars annually to keep the warranty.
