Boric acid has also been widely used in the treatment of wood for protection against termites. The full complexity of its mechanism is not fully understood, but aside from causing dose-dependent mortality, boric acid causes dysbiosis in the Eastern Subterranean termite , leading to the opportunistic rise of insect pathogens that could be ...

Boric acid is only marginally more toxic to most lifeforms than normal table salt, with exposure in humans and other mammals widely regarded as being safe. Its use as an insecticide in malarial control (instead of compounds which demonstrate high levels of mammalian toxicity or carcinogenicity ) is thus seen as advantageous.
The use of a blowlamp to kill dry rot by applying heat to the surface of affected areas was popular at one time. Obviously, this led to the risk of fire. Experiments showed that a surface temperature of about 100 °C (212 °F) would have to be maintained for up to five hours in order to produce a temperature that would be lethal to fungus ...
The simplest way to prepare a BBS solution is to use BBS tablets. They are formulated to give a ready to use borate buffered saline solution upon dissolution in 500 ml of deionized water. Concentration of borate and NaCl as well as the pH can vary, and the resulting solution would still be referred to as "borate buffered saline".
