We had a similar proble to the gentleman from Grand Juncton Colorado although our rodents were mice. A little google search turned up a product by Honda (which his Accura dealer should have known about...). It is called "RODENT TAPE" and it is an electrical type of tape that is impregnated with the chemical that makes hot peppers really hot. Wrapping the wires with this amazing stuff has prevented our mice from eating any more of the insulation off of our vehicle wiring and I suspect that it would be worth trying out to stop squirrels as well. The stuff is expensive - I recall we paid $25 for a roll the size of regular electrical tape. It is gray with little mice printed on it every inch or so. We bought it from an outfit called OEM Accura Parts and the product ID was 4019-2317-Honda. It comes in a role 19 mm wide and 20 m long. For us, living out in the country surrounded by fields and field mice, it would have been "cheap at twice the price"
