Nothing about this is your fault.
Bed bugs are hitchhikers, full stop. They ride home in luggage from a hotel, a kid’s college dorm, a visiting guest’s bag, or a secondhand nightstand. Immaculate houses get them; the only difference between a close call and an infestation is how early they’re caught.
What makes them hard isn’t toughness — it’s real estate. They hide in seams the width of a credit card, feed at night, and their eggs shrug off treatments that kill adults. That’s why a one-pass spray-and-pray approach fails and a staged plan doesn’t.
The smashers handle it discreetly and thoroughly: an honest inspection, treatment of the hiding map, the laundry-and-heat prep steps that actually matter, and a follow-up timed to the hatch cycle so the second wave meets a prepared field.
