Real Experience with Borax wood treatment...?

I've found some mentions of using borax to treat wood in the forums, but not really a good set of instructions that someone has done themselves and has worked well.  Does anyone have experience with this that they'd be willing to share?

My personal reason for asking is that I'm building interior upper floors in a concrete (styrocrete) house out of wood.  There are termites that could on occasion find them.  I'd like to deter them with something that's safe for indoor use.  I'll paint some kind of barrier on any part of the floors that my 2 year old might try to eat.

I've found something online telling me to mix 10oz borax with 6oz warm water, dissolve it, then mix that with 1 gallon of water.  Use a sprayer to coat boards at a rate of roughly 50 2'' X 4'' X 8' boards per gallon of mix.  Would it be better to make a board shaped pool and submerge each board for a moment, or stick with spraying...?

Thanks!

I followed recipe #1 "Equivalent of Tim-Bor" here: http://alsnetbiz.com/homeimprovement/homemade.html

I did this in a big stock pot on an outdoor propane burner, then poured the liquid into a tank sprayer (figured the hot water would make it a lot easier to dissolve the borax and boric acid. I poured it into a pump spray tank and applied it to a firewood rack I had built.  

So far so good in the 3rd year, granted termite damage would be tricky to see. One problem I did have is that the borax crystalized all around the sides of the spray tank. Maybe I used too much powder and it couldn't stay in solution. Not sure, but I had to throw the spray tank away because those crystals were SOLID and not going anywhere.

That's great!  Thanks.  I'll check it out.  Good heads up about the spray tank issue.  If I use a sprayer I'll run some warm water through it after.
