A spider has moved in to my driver's side mirror, and every night it builds a huge web that I have to destroy in the morning, getting sticky gunk all over the door and window. Then every night, it just rebuilds it. I'm pretty sure it's camping out inside the mirror. I don't know how else to get it than to spray water in there, but I'm guessing the components inside the mirror housing weren't engineered to be water resistant... Any thoughts?
