We recently bought a 2017 Toyota Highlander (Platinum Edition) and we love the car and garage it every night. About a month ago we noticed various random items left in the car were being chewed on by something, which we determined were mice. I set some snap traps inside the car and within 24 hours had caught 2 mice. Thinking the problem was resolved I removed the traps after a week of no mice being caught and no mice chewing issues. I also set some traps in the garage near the car and was able to catch a few mice that way. The mice appeared to be getting into the car through the cabin air filter and associated vent system. We know this because the filter itself was chewed through.
A month went by and no mice, and then suddenly this morning my wife noticed that not only were the mice back, but they had chewed big chunks out of the console (presumably trying to get into the console compartment looking for gum). I told her there is no point replacing the console since the mice will continue to get into the car and do their damage no matter what we do.
So at this point all I can think of is to remove any food items from the car so they don’t have a good reason to get into it, and constantly lay down traps in the garage, and specifically in the car, from now until eternity. Any other ideas?
