There were lots of them, in my room.
My sublettor (StefStar) has many, many bites on her legs.
So, I threw away the mattress pad. I vacuumed the entire room. I washed the sheets in hot water. I dropped off the blankets to be cleaned. I shut the window, which, I suspect, is how the spiders got in the room in the first place.
The super is supposed to be calling the exterminator.
Hopefully, that's enough. I'm exhausted.
