Thanks for the comments folks.
On the "good news channel" - I think we got all the little critters. It's been 8 days since I ripped the walls out and six days since we've seen a bug in the house. Now, all I have to do is put up the new insulation and sheetrock. We did get lucky in one respect, right after I ripped out the walls our uber-hot temperatures dropped into the seventies so at least having the uninsulated walls hasn't been cause for a second mortgage to pay the electric!
