Forgive me if it has been asked before but I am new to this NG.
I have noticed that a lot of the homes going up around my development have
little green or white (air?) lines that run around the windows and doors in
the frame of the house and all run back to a central location.
They seem to be about the thickness of about 16 ga. or 18 ga. wire but they
are hollow plastic like air lines.
I have noticed these with many builders, not just one.
What are they for?
If it makes any difference, I am in the Phoenix Arizona area.
Thank you for any help.
Could it be for a "tubes-in-the-wall" pest control system?
WIth that system, you'd run some small tubing all around the perimeter
of the house and back to a delivery station (or stations.) Then, the
pest control person comes by periodically and injects some
insecticide, which is supposed to blanket all the possible entrances
