How long does Bora-Care® last?

Monday, June 18, 2018

Bora-Care has been around since 1987, and testing so far supports the company’s claim that it will continue to provide protection from wood-destroying insects and wood rot fungi for the life of the home, as long as the wood is not subjected to rain or flooding. The primary ingredients are a borate salt and glycol. When insects ingest the borate salt in treated wood, it destroys the ability of their digestive tract to absorb nutrients and they starve to death. Glycol enables the chemical solution to soak deep into  wood fibers.

    Bora-Care also deters subterranean termites from building mud-tube tunnels over the surface of treated wood. They require a moist environment to survive, and mud tubes are the mini-expressways subterranean termites need to protect them from dehydration in open air as they move upward in a wood structure.

    Bora-Care is normally applied only to wood near the ground, as a barrier to keep termites from reaching untreated wood higher up. A color dye in the solution shows where the wood has been treated. The fact that it is not pumped into the ground like other treatments, which may allow the chemical to migrate into the groundwater, is considered an advantage.

   The drywood termites species is able to enter a home from above ground level, such as through attic or soffit vents, and does not require the connection to soil that subterranean termites need to survive. This means they are able to bypass a Bora-Care treatment and infest a home starting at the top. So regular wood-destroying organism (WDO) inspections are still a good idea for homeowners.
