From what I've seen, it looks like Toyota uses a cross-linked polymer insulation not derived from soybeans, but I'm not aware of Toyota confirming their insulation choice.

In my case, my avatar hunts with a couple of buddies...rodents can't get through their defensive lines around the house, and another 3-4 feral cats take care of the barn. Their defensive line works perfectly 24/7/365. We're less than half a mile from the Birds of Prey National Conservation Area so between the cats and eagles, hawks, and owls rodent's don't have a chance.
