The new section of the house had been built over a crawl space, and the crew was able to apply a borate product (Tim-bor) to the floor joists. The crew used the same treatment in the attic on the building’s original rafters that were infested with termites. On the exterior sill plates, where wood was damp, and on some damp floor joists, they applied another borate solution (Bora-Care).
“We did the treatment a year and a half ago, and there’s no sign of new infestation or rot,” Ocampo says. “Our next project is one I’m really excited about. We’re going to treat all the wood at Mission San Juan Capistrano.” One of the advantages of borate is that it allows homeowners to keep on top of termite infestations or incipient rot without having to use toxic substances. Borate is nonrestricted, which means anyone can use it.
It’s important to know which product to use and how to apply it. To treat an entire house, you’ll probably want to hire a trained operator who has the equipment and know-how to apply the product correctly. For a small infestation or a follow-up treatment, you could do the work yourself.
