I've lived in TX for 30 years off and on (going to be on again, be forewarned); I never had enough spider left to use a magnifier on.
To be fair; if it's in the house, it's dead. If it's in the yard, I just give it some room. Of course, everywhere in the world is within 5 feet of a spider.
I had to refrain from smashing the CRAP out of them before I identified. I was a nervous wreck about recluse spiders! I probably had them, but never knew!
