Cheiracanthium mildei
(Long-legged Sac Spider)

Hi.They are venomous like most spiders but not medically significant. They don’t run around biting,but prone to bite if trapped against the skin. Most claim some pain, possible local swelling, often compares to a bee sting. They are all through my place, worst is webbing from the ceiling in front of your face watching the late show, had to pick a couple off the bed and put in a corner out of the way. Just never bitten.

They might do that, worst is smacking them against the skin. Very skittish with hands,they will run off you with a little coaxing.
These spiders were the subject of the big Mazda recall for them getting into fuel system vents.
My place I was talking was Mountain Home BTW.
