That’s the title of this article, written by someone who had bed bugs.
She speculates that she may well have gotten them from eBay. Or from a roommate who is completely unaffected by the bugs, but who likes to travel. (Maybe he brought them home, but, unallergic, never noticed them).
She also has an experience some Bedbuggers have shared here, seeing a neighbor obviously cleaning up their own infestation (never disclosed to the author). Though she does not suggest this, the bugs may well have come from the neighbor–perhaps this is the most likely scenario.
We often think we know where our bed bugs came from. Some, like this author, and our own Jess, speculate about the source. In Jess’s case, she later discovered she was wrong, but only after telling the world she got them from a friend’s secondhand mattress.
The lesson is this: you think you know where you got them, but you don’t. Had she found out her mattress-giving-friend had bed bugs, Jess probably would have stayed with that explanation. Instead, other more likely scenarios came to light.
People often say in the comments or on the forums, “I am going to sue my neighbor who gave them to me.” But you can be bitten for months with no reaction; you could have given them to the neighbor. Landlords, too, may blame new tenants for bringing them in, when all the while, the former tenants could have been infested and not even known about it.
Tricky little b@#$%^&s, these bed bugs.
