Thanks @downandlonely

The maintenance person came and inspected my room yesterday and didn't see any sign of them, so they think it was a random stray that I might have brought in on my clothes.

But they're having the exterminator come check my room on Friday morning, They've said he probably won't spray, but will put down the earth and put traps on the legs of my beds.

I still have to do a fair bit of prep, but the maintenance guy is going to come by tomorrow morning to help me move things and get ready.

I'm really happy how on top of things staff have been.
