My two neighbors feed the deer. This brings in many other critters to clean up after what the deer miss. Thanks for the tip. Sounds like a good simple preventive that is non-destructive and fairly inexpensive.I had rodent issues in my old car. They managed to nibble on cable covers and eat most of a plastic air intake. A mechanic suggested spraying Simple Green around the wheel covers at the base of the engine compartment and under the hood. This worked really great for me. No more rodent issues for the subsequent two years until the car was sold. I repeated the application once a month or so. Apparently rodents really do dislike its smell.
