We've tried several things to deter rodents. The only thing that has worked consistently and completely is putting a shop light under the hood. I plug it in with an extension cord over to my carport and a dusk to dawn timer. When we are on an RV road trip, we leave one car in the carport. I do the same thing for it, but I just lay the shop light on the ground under the engine.
I took this one step further, I installed a strip of cut to length LED lights around the inside of the engine compartment. The plug is on the right side of the bumper, and plug in ever time I get out of the truck.
