My dad lost 2 new sets of spark plug wires to pack rats. He switched to a brand that didn’t taste like peanuts.

Lost an antilock brake sensor recently. We bought a rid-a-rat (flashing light that makes the area seem unsafe), but that only protected half the engine bay, so I put a light bulb on an extension cord on the other side and put it on a timer.
