Seeing my newly thatched roof being attacked and disfigured by what I suspected were mice, I rang A.C.E Pest Control and was impressed that an expert could call within the hour. On arrival, he closely inspected the damage and gave his opinion that the damage was being caused by crows. In addition, he looked at the measured I had taken and judged that I was doing all that could be done. He then suggested changing the covering wire position, which made a lot of sense. There were no pressures sales, just sound advice and if I have any future pest problems I will definitely use this helpful and honest company.
