far, I'm not able to see or hear any other evidence of activity, but granted
I don't have x-ray vision, etc.

At this point would it wise to be immediately be seeking professional pest
control treatment, or could this likely be a waste of my money? I'm
imagining that a pest-control company would typically tell the homeowner
their house definitely needs professional pest-control treatment (since
treatment is what they get paid for). If only a professional can
determine this, then how do I know they are telling the truth (since they
are biased because they get paid to do the treatment)?

Thanks,
