If it were me, I would call an exterminator. Anything under $200 would be totally worth not having to deal with it and knowing that they’ll take care of it better than I could.

Spiders in general is one thing, but a ton of black widows is something I wouldn’t mess with. Those spiders could make you quite sick if not ending up in the hospital. Shieeeet. If you’re of a vulnerable population like elderly, young, or already sick, they could kill you.
