I would also get written confirmation from your previous landlord that you vacated the premises on xx date, and that the unit you vacated does not have, nor has it ever had, bed bugs.
That is a really good idea thanks.
I've tried to contact my LL today - with no luck thus far. I'm certainly going to stay on top of this, my mental well being can't handle it too much longer. Thankfully I have friends who have offered to let me stay at their home, but I'm so nervous that I'd be taking them over there. :/
