The guy I helped move in slept in the house 1 night and was bitten by bed bugs.
While this house was vacant the bugs would have travelled into the walls making these little fuckers undetectable to cleaners and even to the naked eye.
These bugs can detect the heat off of humans within 9 feet of themselves.
Although I am incredibly sympathetic to this tenant, I’m glad I wasn’t there long enough to bring them to my home.
He has since received heat treatment paid by the owner and is bed bug free.
