I'm not a big fan of spiders...but then I'm not terrified of them either. Have thought I've found false widows loads of times but upon closer inspection they are almost always common garden spiders of one type or another.
I get bitten by spiders several times a year at work and they are just like slightly more itchy much longer lasting Mossi bites in my opinion. Did have a real false widow make its way into my armpit last autum and dispite being there for over 5 hours and me scratching the tickley bit of shirt thread I presumed it was several times it didn't bite me and when it fell out on the kitchen floor when got home and took my top off, it was captured...positively id'd and set free in the front garden, I figured if it hadn't biten me all day (dispite the smell of my pits lol) it deserved to live
I'm not opposed to killing things that need killing....but if I'm not going to eat it and it hasn't or isn't going to hurt me...then it's live and let live in my world
