Mice just did $1200 of damage to the wiring in the engine compartment of my 2016 wrx. I’ve looked at a number of articles and posts but I’m not sure anything is promising to prevent this from happening again.
Most of the prevention methods are questionable, not applicable or impracticable for a daily driven car.
The car is daily driven. Parked in my driveway. I do not have mice in my house but I did find they got in the grass seed in my detached garage. Other than the grass seed I am not aware of any food sources.
The cable they ate is under the intake and very difficult to access. The dealer had to remove the manifold to replace it. So I don’t think Honda rodent tape or possibly even spraying with cayenne pepper is an option
I’ve mothballed up the garage and set snap traps in there. I have a bucket trap by the garage killed 7 mice the first couple days but the following week has been quiet. Also hung a fake hawk above the garage door overlooking the driveway.
Ultrasonic deterrents sound waves are easily absorbed by blocking surfaces so I’m guessing they won’t penetrate into the engine bay plus anyone who knows about the importance of hearing protection knows a mouse will just become deaf to that frequency eventually.
I hear bounce dryer sheets and Irish spring don’t work but heck they can’t hurt.
Last rodents were covered under my comprehensive auto insurance so I’m only out $500 but this has been time and money I don’t want to spend again.
