Just to remind you that you can’t call me in to perform a dog  inspection in a room that has beed treated within the past 30 days.  My very sensitive olfactory cells would easily be impaired.
However, it makes a lot of sense to inspect adjacent rooms, left and right  and up and below the infected room to determine the extent of the infestation.
Finally, if you want to follow up with a treatment soon after the inspection, I can recommend several pest control companies I trust and work with.  Call me with any questions, any time at 508-713-8267 or fill out a request form here.
