I told my wife about this hilarious spider thread and the various solutions suggested like nuking and burning the vehicle. She tells me she’s had a spider web in her exterior passenger mirror every morning for many weeks. She wipes it away in the morning with a towel, the next morning it reappears.
I go out tonight to take a look for myself. Sure enough, a large scraggly spider web between the mirror and window. And a large dead beetle was caught in it. (WTF was a beetle doing looking in the mirror?). So I get out the shop vac and suck up the web, beetle, and all around the mirror and all the gaps behind it. Then I spray window cleaner in there, mostly isopropyl alcohol. Then permethrin insect repellent. Let’s see if the bastard survives that attack!
EDIT: As of two days later, the spider is gone!
