My apologies if this has been discussed recently, I wasn't able to find a
reference to it on deja news. Thanks!

In a recently built home, there is still a lot of moisture from curing
concrete, drywall mud, wallpaper paste and even final clean-up. That
would probably explain the frost. A typical electrical box extends
almost the entire depth of a 2 X 4 stud wall. In a good job of
insulating, the insulator will place some insulation behind the box-
between it and the sheathing, will cut insulation carefully to fit
around the box and will even SEAL openings where the wire penetrates
the box. Frequently, this isn't done. To complicate matters, the
wire's bends by the box can even prevent decent insulation within
several inches of it.
In my own home, I remedied this by using foam that I squirted OUTSIDE
the box before insulation. It foamed in behind the box and also
sealed all openings. It gave the glass insulation something to "wrap
around," as well. I don't know if this is a recommended practice, but
it sure as heck prevented drafts.
There are commercial products for after market sealing of an outlet or
switch. The product is a latex foam gasket that is die cut just a tad
smaller than the cover plate. By installing it between the wall/box
and cover plate, it seals out a draft. Additional gasketed plugs plug
into the duplex receptacle to seal it as well.
What I would NOT do is to stuff any insulation into the box or to
attempt to foam it in.

If your local co won't supply them, they cost a couple of dollars per
dozen at a hardware store.
