Yes, it absolutely does kill black widow spiders. We found the one pictured (large and very pregnant) in the back yard about a month ago, and my boyfriend used this product to kill her. One solid spray and she was dead. We have killed several other large spiders in the yard with this product since then. I think the trick with the larger ones is to hit them with it directly (not just spray in and around their homes).

Doubt it. It doesn't seem effective on larger spiders. Read my review if you need to know more.

Wilson One Shot Spiderban Aerosol has not been registered for control of
Black Widow Spiders, therefore it would not be guaranteed. That being said,
there is data out there that indicates the active ingredient Permethrin
should have some effect, possibly controlling Black Widow Spiders. Both,
direct contact, and sufficient spray would need to be applied directly to
the Black Widow Spider for the product to have any effect.
