I found this little guy amongst 100s of others the same size and bigger at my work. They are under an overhang shelter to an old bombshell bunker that i had to hose the nest and webs off from hanging. Theres plenty of lights that constantly stay on under there. And these critters are couped up in small round tunnel webs and balls of a messy webbing. Im wondering what they are and if they are poisonous. They are pretty big up to 2 1/2 inches including the leg length.

Female Crevice Weaver Spider

Hi Keith64,
This is a female Crevice Weaver Spider,
Kukulcania hibernalis, and you can compare your photo to this image on BugGuide.  According to BugGuide:  “Females are frequently mistaken for small tarantulas or trapdoor spiders. Males are often mistaken for recluse spiders (Loxosceles). This is a totally harmless species that builds ‘messy’ webs emanating from crevices, often on the outside of homes.”  Eric Eaton has an excellent blog posting on Crevice Weaver Spiders on Bug Eric.
