Disodium octaborate tetrahydrate, an alkaline salt, is produced in two forms. One is a clear, liquid concentrate, which can be mistaken for corn syrup if repackaged and not properly labeled or it is packaged as a white, odorless, powdered chemical substance that is not flammable, combustible, or explosive and has low acute oral and dermal toxicity. This salt, which is commonly confused with boric acid, is used as an insecticide and is commonly sold in liquid or powder form. It is also effective against fungi and algae. It has an infinite shelf life and is not affected by temperature. "Bora-Care" is the liquid form suitable for use in a sprayer. The powdered brands are "Tim-Bor," "Borathor," "Termite Prufe" or "Board Defense" as sold in the United States, and as "Can-Bor" in Canada. This chemical is also a flame-retardant. In the liquid form, it is commonly diluted and sprayed on wood surfaces to kill termites, powder post beetles, carpenter ants, fungi and algae. It is also available as pellets for embedding in structural wood. This alkaline salt is not to be confused with boric acid (an acidic chemical) or the laundry detergent additive used for stains.
In common use as a termite control or for termite prevention, the liquid concentrate is used at a ratio of 1:1 with water. The advantages to this chemical over conventional pest control treatment is that it is non-carcinogenic and has a low toxicity to humans and pets. It is also odorless and proper application lasts for the lifetime of the wood. Repeat treatment is not necessary. It is best used during new construction, however, it is more commonly used after the fact on homes originally treated with chemicals that have become inactive.
It was shown to significantly reduce dust mite populations in the home when combined with regular vacuum cleaner use.

Safety
Disodium borate in its disodium octaborate anhydrate and disodium octaborate tetrahydrate forms is classified as "reproductive toxicity category 1B (presumed human reproductive toxicant)" under the EU Classification, Labelling and Packaging Regulation (CLP Regulation). The CLP hazard code and statement are "H360FD: May damage fertility. May damage the unborn child."
On 22 February 2018, the Swedish Chemicals Agency (KEMI) submitted a proposal to the European Chemicals Agency (ECHA) to list disodium borate as a Substance of Very High Concern (SVHC) under the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Regulation.
