[Greenbuilding] Reusing wood in Katrina Formosan quarantine

[Brad Guy]

We are working on deconstruction and reuse wood
projects in NOLA and adjacent counties in Mississippi.

The State of LA has placed a quarantine on reuse of
any wood from the 9 parishes around and including
Orleans unless treated for Formosan termites.

I am looking for any thoughts/suggestions on "best"
preservatives that is also least toxic - which we know
can be an unfortunate oxymoron - the reuses would be
exterior or interior and non-ground contact.

A list of products I am aware of:

Tim-bor
ACQ
Copper Azole
Bora-care
Advance Guard
Any others?

Any recommendations on any of these?

Thanks for your help,
Brad
