Tasty Wiring

It seems that certain manufacturers are using wiring insulation that is attractive to rodents: Article

Sounds like a great science fair project for some high schooler out there, do mice prefer the new wiring vs the old.

    And there you have it. Don't ***** when dropping a thousand or two to rewire your car. You'll just be doing your own part to save the Earth. It's always the well meaning things imposed that backfire.


    Rats chewed the wiring in my truck 25 years ago.

    Some wiring uses a soy based insulation. Rodents LOVE to chew on that. They think it is soybeans.
  • Shoot. the dogs i got to protect my Tt did more damage than any rodent. Those dogs cost me over 200 bucks to have the brakes, and the tanks rewired. Then i had to build a fence around the TT to protect it from them.
  • When squirrels got into my 5er they ate not only the wire, but also the water lines. I first thought they were chewing through to make a nest but on closer inspection I could see they were eating my water hoses like an ear of corn.
  • There are additives that could be used in the insulation, not Capsaicin, that would make it quite distasteful for critters to nibble on. Denatonium aka Bitrex is commercially available, and is one example.

  • It's not just mice OR Asian/European Imports

    Last summer had Grid Heater Bad Low Voltage Code and then passenger side battery cell tops blow off when went to start truck one afternoon.

    Squirrel(s) had eating thru insulation behind battery under fender area causing a short.

    Vermin are a troublesome lot..........period
