PCC representative Eric Avelar analyzed our rodent situation, which two other companies had attempted to treat. Eric pointed out that to solace the problem would probably require a total reroofing of the house, and the best way, short off that, was to trim trees back even further than I had already done. He also went immediately to the air conditioning condenser and found a near ground entry on a line that goes into the attic and filled it. Having studied the problem myself, I am convinced that he was being the most honest and realistic of the people top look the problem. I highly recommend this company and Eric.
