Hi - I started seeing bed bugs on the wall and ceiling in my living room a few weeks ago. Initially I didn't know what they were so I was just vacuuming them up. A few days ago I finally used a bug identifier app and learned they were bed bugs. I haven't seen a swarm yet, I just see one or two everyday. I have a professional bed bug exterminators come in to assess the situation today and tomorrow.
The question is, assuming I go for the heat treatment, will the entire house need to be treated? I got 3 quotes - they're all expensive, but something in the line of $700-1400 for the first room ($1400 incl. kitchen/living/bath as well) then $300-400 for ea additional room. So for the entire house I'm looking at $2,000 or more for 1,050 sqft house. My priority is that I eliminate them completely before the situation gets worse, but I'm concerned that I spend all this money and it's not effective (bed bugs come back) and I'd have to do it again.
Any recommendation? And I should go for heat treatment, not chemical, correct?
