Spider out in the woods, I watch it for a bit and go on my way.
Spider indoors, I enter the Con Darr, and will hunt it down no matter how long it takes or the furniture I have to move.
I have a pair of black leather gloves within reach of this computer at all times, as well as a sword. For the ones in hard to reach places.
The funny thing is, I have probably 12 or more in my room, under my bed, and elsewhere. Yet I have no end of "mosquito eaters" aka huge flying bugs the size of ping pong balls or bigger that will come into my room, fly right on to my screen and scare the crap out of me.
If I found even one of those fuckers in a web in my house instead of scaring the bejeezus out of me I might see a benefit to spiders.
But the many spider bites I get in my sleep would still outweigh that. I'm also not a spider expert, only knowing a black widow is bad news on sight. I've also seen so called "harmless" spider bites result in necrosis or partial liquefaction of tissues, though not on me personally.
I also used to wake up screaming almost every night as a kid having spider related nightmares, and one time I woke up and discovered I couldn't open my left eye because it was swollen shut due to a bite.
I got taken to the hospital a few other times when bites caused my arm to swell up dramatically.
Still spiders are ok compared to carpenter ants. We rented a house out in the middle of no where once that had a huge ant problem.
Fun fact: the ant's head will keep biting you long after you pull its body off of you. That place also had black widows and I was 6 years old so they probably could have really hurt me. Fun times...
