I am a worrier/thinker and have had problems with ants and electricity in the past. Those little PITAs would find their way into the points of our well pump pressure switches at the ranch and short out the entire system. We would have to periodically pour Sevin dust around the post that held the points box and try our best at sealing the box with silicone to keep them out. I don't know why ants have an affinity for electricity....but they do. I don't think that ants would climb past the rubber tires to get into electrical components of the Model S but wanted to throw this topic out for discussion. Do you think we should be concerned about this?
