I'm so glad I found my people...
So, I have a similar spider situation in my 4Runner. It started developing ever since I started leaving it parked under the trees in my driveway. I see their webs, and their egg sacks, and occasionally I'll see a real chest bursting sized one just waiting for me to let my guard down.
What the ever loving **** do I do!? Bug bombs sound like they're going to damage my precious 4Runner.
Sticky traps and NuVan pro stips? I will ****ing roll my 4Runner if one gets within 5 feet of me while I'm driving.
Much like OP, I am certainly unafraid of scary things (I climbing ****ing mountains and sheer granite cliff faces for Christ's sake...for fun), but these 8-legged spawn of Satan need to be sight unseen for me to be at ease.
Help me Obi-Wan Kenobi...
