SOLUTION NEEDED

There is a spider living inside my passenger-side rearview mirror. Either that, or a self-regenerating spiderweb was placed there by magickal faeriyes. Since I'm pretty sure the latter is not a real option, I am now wondering how to go about getting rid of the damned thing. Clearing out its web every time I squeegee my windows at the gas station does not seem to be providing the necessary hint. Driving at high speed through rain has not proven to the spider that its chosen habitat is suboptimal. I don't have a readily-accessible hose at home with which to direct a targeted spray into the mirror's inner workings. What now. What now.
