This looks like a cobweb spider but I’m unsure. I find them in the corners on the base molding. They are tiny right now no bigger than a pin head but I worry it could be a widow and I have young children

Hi, it looks like Steatoda triangulosa, a Triangulate Cobweaver. Yes, cobweb spiders are the family, Theridiidae, that black widows are in, but they vary greatly in venom potency to humans. The genus Latrodectus contains the spiders with the most necrotizing venom to mammals. The false widows, like yours, are very common in the world. Their venom is most potent to crawling insects and other spiders.
Doesn’t necrotizing imply that it causes necrosis? I’d say their venom is “latrodectizing” or “potent”.
