Weird thing... I went out there will my armload of towels, brushes, vinegar, etc., etc. and the Shop Vac. There was absolutely NO ODOR of any kind and not even a tiny bit of dampness. When I touched it, it almost evaporated. No odor on my hand either! So I vacuumed it really well then brushed it thoroughly with white vinegar. I have the heater/fan running to dry that, too. I can't find any dampness anywhere in the area. So I don't know what it is/was, but it's not the big problem I thought it would be. I think I'll use some DE when it's all dry, just to be on the safe side. I think I dodged a bullet today, and hope I'm not missing something that's going to come back to bite me! Thanks for the info. on lifting a carpet and using the putty knife. That would work in the house, but the trailer doesn't have molding along the edge. Yeah.... that's worta what happened to me too! But you could do what SadieSue is doing... just raise them for a while and then sell most of them!
