Thank goodness you kitty alerted you to carpenter ants, you were lucky to catch this before serious damage occurred.
The pest companies do play on the fear factor to the point of calling you back and wanting to do a free safety inspection. It is a search for anything that might be slightly suggestive. We look at it as a way to drum up business. Same deal with the automotive repair industry, you take your car in for something minor and end up with a suggested-recommended list of lots to be done...flushes, inspections, replacements-adding up to a handsome sum of money, probably enough to pay for a semester of college.
We took our car into a chain tire place because the tire pressure indicator light was on, please just check the pressures and add air where needed. Then we can go down the road and the light will go off because the pressures are ok. Oh, no, they wanted $52 to reset the computer, fortunately we had a good mechanic there who was kind and did it for free. The business desk man wanted money, the company line.
