Was she a crazy CAT lady by any chance?
The sheer volume of bedbugs seen in some places seems to defy the idea that they are dining only on people’s blood. How do you get all that bedbug mass? The crazy lady would bleed to death. I think there has to be a connection with other, warm blooded vermin.
No cat lady. This was a row of apartments side by side. They just spread out to other apartments. The management had people out spraying and then my aunt had her granddaughters hubby out spraying. My aunt actually fell and broke both wrists trying to turn her mattress by herself looking for bed bugs. They drove her nuts. She had the beginnings of dementia so they really got to her mentally.
