When I lived in San Diego I used to feed one in the garage crickets. Then on day I was changing to sparkplugs in the truck when I put the hood up it hot some webs but not paying attention I started on the plugs, I felt something on my arm and it was a Black widow spider. I brushed it off and I didnt think it bite me. the next day I had went fishing had to spend half the morning hitting the shore with the squirts and then that night I got a fevor, then I got a half the size of a tennis ball lump on my arm which eventually poped like a Zit. then 4 months after I got the half tennis ball thing again, and then again at 6 months....dont want to sound so graphic but them things are bad news
