Boric acid, also called hydrogen borate, boracic acid, orthoboric acid and
acidum boricum, is a weak, monobasic Lewis acid of boron, which is often
used as an antiseptic, insecticide, flame retardant, neutron absorber, or
precursor to other chemical compounds. It has the chemical formula H3BO3
(sometimes written B(OH)3), and exists in the form of colorless crystals or a
white powder that dissolves in water. When occurring as a mineral, it is called
sassolite.

Boric acid may be prepared by reacting borax (sodium tetraborate
decahydrate) with a mineral acid, such as hydrochloric acid:
Na2B4O7·10H2O + 2 HCl → 4 B(OH)3 [or H3BO3] + 2 NaCl + 5 H2O
It is also formed as a by product of hydrolysis of boron trihalides and
diborane
B2H6 + 6 H2O → 2 B(OH)3 + 6 H2
BX3 + 3 H2O → B(OH)3 + 3 HX (X = Cl, Br, I)
1. Insecticidal
Boric acid was first registered in the US as an insecticide in 1948 for
control of cockroaches, termites, fire ants, fleas, silverfish, and many other
insects. The product is generally considered to be safe to use in household
kitchens to control cockroaches and ants.It acts as a stomach poison
affecting the insects' metabolism, and the dry powder is abrasive to the
insects' exoskeletons. Boric acid also has the reputation as "the gift that
keeps on killing" in that roaches that cross over lightly dusted areas do not
die immediately, but that the effect is like shards of glass cutting them apart.
This often allows a roach to go back to the nest where it soon dies.
Cockroaches, being cannibalistic, eat others killed by contact or consumption
of boric acid, consuming the powder trapped in the dead roach and killing
them, too.
2. Preservation
In combination with its use as an insecticide, boric acid also prevents and
destroys existing wet and dry rot in timbers. It can be used in combination
with an ethylene glycol carrier to treat external wood against fungal and
insect attack. It is possible to buy borate-impregnated rods for insertion into
wood via drill holes where dampness and moisture is known to collect and
sit. It is available in a gel form and injectable paste form for treating rot
affected wood without the need to replace the timber. Concentrates of
borate-based treatments can be used to prevent slime, mycelium, and algae
growth, even in marine environments.
Boric acid is added to salt in the curing of cattle hides, calfskins, and
sheepskins. This helps to control bacterial development, and helps to control
insects.
