The soy-based coatings are a perfect chew toy for rodents, providing excellent nesting material and a near-endless supply in a warm, hidden spot. If you’re a mouse, it’s the greatest thing ever. But if you’re an owner waking up to a severed fuel line, it’s a little less enjoyable.


Maybe Soy-Based Wiring Is Too Eco-Friendly?



They are chewing wiring covers more often because auto manufacturers have switched from using petroleum-based plastic to protecting the wiring with a vegetable-based type of plastic,the move was part of the car industry’s green movement.

In January 2016, a lawsuit filed against Honda claimed the soy-based wiring was irresistible to rabbits. Later that year, a similar lawsuit was filed against Toyota. In July 2017, Hyundai and Kia sued for using soy wiring.


In each case, the automaker was accused of concealing the problem and/or refusing to fix the issue under warranty.Soy-Based Wiring Is Too Eco-Friendly?

However, regardless of whether wires are covered in soy-based materials, it’s a fact that rodents are drawn to them. RV, Boats, and car owners alike have wrestled with this issue for years.

The damage caused by rodents can result in costly repairs. These repairs typically aren’t covered by your car’s warranty.

Rodents Nesting In Your HVAC Unit?


An air conditioner is a perfect place for a mouse because the air ducts contain materials they can use to build suitable nests. They will chew on whatever they can find. When they begin to feast on HVAC electrical wiring, your home’s safety is compromised. Chewing through a wire can lead to an electrical fire and a damaged HVAC system. When rodents find their way into your ductwork and make nests or leave droppings behind, tiny fecal spores are swept along by the force of heated and cooled air moving through the ducts. These spores make their way into your home and contaminate the air quality.
