Man, that’s tough. I dunno, I found a single, live bedbug in my apartment once on my computer desk. I killed it immediately and blood came out, but then I never saw another one again and lived there for 2 more years.
Since your money is tight, you might want to get out before you incur fees and owe rent. Did you get the place through an assistance program? If so, I would notify them about the bug as well.
Bed bugs are BAD. Where was the bug when you found it? Was it on you, the floor, your stuff? Was it alive or dead? Could you stay there a few more days without bringing the rest of your stuff from your friend’s place and see if more bugs appear?
Bed bugs spread quickly and can travel on you or your clothes and infest other locations. That being said, it may have just been one. Then again, if it came from the apartment next door, more will likely infiltrate your place. If they are coming from next door, it won’t be enough to spray just your apartment, the entire building will need it.
Sorry for the difficult situation you’re in, this is a tough call.
