lmao...Marc, you know you want some of them!! haha

When I've kept them, I've used larger deli cups, or plastic containers with lids.  I usually use forest bedding for substrate, but since there are slings, I've left it bare.  Right now these are in a big plastic jar.

I put a piece of bark, or small branches in to give her something to build a web on.  It's fairly easy to remove the bark using hemos or small feeding tongs, spider and all.  Then I can clean out the container, and just replace the piece of bark.  Room temps are fine, as they really are hardy animals to keep. I make sure they don't get too hot/cold and feed it a variety of insects. I think they are some of the easier to keep spiders, just don't get bit!

Sometimes I will.   I have my Dubia colony too, so I can offer small roaches.   I have TONS of large grasshoppers around the yard, so I usually sacrifice those.  I put in a couple of aphids for the slings, but I think they are still too large.   I've never kept slings, so this is new.  I'll try to squish a grasshopper in the container later and see if they will eat it.  Once they start getting a little bigger (if I manage to keep them alive) I'll separate them out into smaller groups, 400 subadult black widows in one container isn't my idea of a party.  lol

You didn't already know that? And I'm sure you will yell if you find more! lol 
   "AAAAAGGGHHH!!!!"

I'll stick to to the adults for now. I usually have friends that like to keep widows.   I believe there was also a group that was doing a venom research, and they were collecting both Loxosceles reclusa & L. mactans from our area.  I don't know if that's still ongoing, but if you turn up several, I can contact them.

Nice! I used to keep a few of these. I even sold them for awhile to arachnid hobbyist friends online. When I was in Monticello they were plentiful!
