I have a large number of both Brown and Grey squirrels who have chewed thru phone and cable wires, pressure treated wood on my deck etc. I have tried everything mentioned in this link, from the capsasin to Tabasco sauce, and the list goes on. I currently have installed bird spikes which I watched this morning the squirrels navigate thru the spikes!! I tried live traps and they won't go near them. I would welcome any suggestions at this point. Last week the Satellite Dish Company had to replace all my outdoor wiring because it was chewed thru :(
