You had me at “tarantula migration“
Black widow's are pretty chill, but they're difficult to spot and hide in things.
Brown recluses OTOH are demons.
In the world, the horrific are the huntsman spiders of Australia. Just search Youtube for these monsters. I'd find some other place to live with normal arachnids.
Brown widows are a pain in my rear. Unlike black widows, who outside will hide in holes and places you general don't access, brown widows will hide in places you do - places that aren't pitch black during the day like outdoor toys, and under chairs and tables.
Had phantom black widows on me for days. But they were pretty docile.
