Having a baby around makes it so easy to freak out

Kid 1 noticed some baby black widows in our room. So Spouse went all around and squished a bunch of them--maybe fifty or so. Pre-baby, I'd be like, "good thing their little baby spider fangs can't penetrate my skin!" and then I would have slept blissfully in my room. But who knows about how penetrable infant skin is? And it probably wouldn't take much venom at all to kill a eight/nine pound baby. All my googling told me nothing. I called poison control and the guy on the other line went off and did a bunch of searching but couldn't find a definite answer about whether a baby black widow could hurt a baby human. The poison control guy said he'd worked there for 12 years and hadn't previously been asked that question. He said that he would be concerned, though, and suggested we put the baby in a different room tonight and fog the room tomorrow. Spouse says that if you fog a room, the poison never comes out of the carpet and that we shouldn't do it. Argh! No path to peace of mind!
