What are Borates?
Borates are low-toxicity minerals with insecticidal, fungicidal, and
herbicidal properties. They do not evaporate or volatilize into the air
like synthetic pesticides, nor do they pose the considerable health
concerns associated with synthetic pesticides. Many consider borates no
less toxic to humans than table salt.
And as a testament to their low toxicity levels, borates have been given a “Least Toxic” rating by the National Coalition against the Misuse of Pesticides.
How We Use Borates to Kill Wood Destroying Organisms
Borate powder is injected into cracks and crevices, where it forms a
fine layer of dust. When borates are applied to wood, the wood becomes
toxic to Drywood termites and other insects while having no adverse effect upon
the occupants of the structure.
Insects
travel through the boric acid, which adheres to their legs. When the
insects groom themselves, they ingest the poison, which causes death
within three to ten days. The continued presence of the borates in the
wood ensures that hatching insects are exposed and die. In fact, many
borate treatments can be effective for more than a year.
An EPA assessment of a boric acid pilot pest control program conducted
at the U.S. Army’s Aberdeen Proving Ground in Maryland found that boric
acid was both more economical and more effective than monthly spray
treatment. At least one study has shown that the combination of heat,
110 degree F for two hours with boric acid, will increase the speed at
which the German cockroach is killed. (Source: Safety Source for Pest
