Borax for Termites in Wood?

[mgonzalez at dhvx20.csudh.edu]

Does anyone know how and if I could make an insecticide for 
termite infested wood with a water solution using
orthoboric acid, i.e., how much water to borax? and will this 
solution be good to treat termite infested wood?  There is a 
commerical chemical called Timbor which is applied in solution 
to the wood to rid termites and avoid them comming back - I 
take it that the Timbor they use is primarily a borax solution, 
probably with  something else, but I'm hoping it  will  work 
with just the straight borax.  This commercial company uses 
this instead of fumigating the entire house.  Also, I take it 
borax is quite harmless, we sometimess use  the powder for 
other insects and I was also wondering if breathing any of 
that power could do harm.
