Howdy - Can some gracious expert explain to me how bedbugs can re-appear after months of absence in a house - in the middle of the summer?
Bedbugs just aren’t supposed to be dormant when it’s warm and humid - and yet in my girlfriend’s house, they first appeared ~8 weeks after she bought a second-hand bed (the only source we can identify). We then paid for a proper treatment (the infestation was very minor), and the bedbugs disappeared for a full 3 months before suddenly reappearing.
How does this work - like, biologically? What could possibly be the source of these surreptitious, Russian spy sleeper-cell-like little bastards?
Thanks in advance!
