Q: Borax wood treatment
Is there a chemist in the house?
Thinking to put some as a preventive measure against termites.
Home Depot: Termite Powder 5 lbs, $9/ lb. Ingredients: Borax, namely Disodium Octaborate Tetrahydrate, https://www.homedepot.com/p/Harris-16-oz-Termite-Powder-Pack...
Home Depot: Laundry Additive 4 lbs, $1.10/ lb. Ingredients: Borax, namely Sodium Tetraborate Decahydrate, https://www.homedepot.com/p/20-Mule-Team-65-oz-Borax-Laundry...
There are no other ingredients in each one. Quick search shows same uses for either substance.
Same thing, different labels?

But how will the termites know it is for them if it says Laundry Additive on the box?
Actually, I think you are on to something. We have been using the laundry Borax for those teeny tiny ants and it seems to work. We mix it with honey
or maple syrup and leave it out as bait. They like it. There are on line directions for mixing with sugar and hot water. Does help with the ants.
How were you going to apply it for termites?

Out of curiosity, I looked it up.
Sodium Tetraborate Decahydrate - Na2[B4O5(OH)4]·8H2O
Disodium Octaborate Tetrahydrate - Na2B8O13·4H2O
Some of the numbers are subscripts, which didn't come through in the copy and paste.
These are both sodium borate salts. Boron (boric acid actually) is the lethal element to insects. The disodium salt has 8 boron atoms per molecule,
the sodium salt has 4 boron atoms per molecule, I'm guessing that makes the disodium salt more effective.

Thanks. Disodium (aka Termite Powder) also has less water per molecule and WT % (is it weight %?) 98, while laundry additive is WT%: 60-100%. Looks
like Termite Powder is "somewhat" more concentrated. At 8 times the cost.
Jefe - I'm going to mix it with water and brush onto the wood. Probably the more expensive stuff - once.
Laundry additive will be good to dust/spray around for cheap, later, once in a while. Didn't see termites yet, only fire ants.

Here is a tutorial on how to kill ants, especially Argentinian ants. https://www.cnpssd.org/chapter-blog/2017/5/7/general-stateme...
Boric acid won’t do anything to active termites.
Borate is used in treating lumber to prevent termites. Borate is applied to framing lumber before skinning frame. Prevents them from entering the
wood.
Once inside the wood, only way to get rid of them is to tent bldg and gas them.
Woke!

Alm, Goat has it correct. Use Borate on new lumber during new construction. The stuff wont do any good on an existing building. The wood has to be
coated on all surfaces of the wood to be effective. And you cannot do that on an existing building.
For an existing building hire the exterminator to come and inject his poison in the the sub surface under the building. The guy I hired in San Felipe
uses the same product that the exterminators in CA use.
FYI, I replaced some termite damaged wood and I used a Borate solution on the replacement wood I used the product that Bluwood uses for their lumber.

It's alright, wood structure is not infested yet and not walled.
