Hi-bor borate pressure treated products are protected from damage by termites and fungal decay. In addition, borates act as a broad spectrum insecticide, effectively controlling many insects, including ants, silverfish, and cockroaches. Borates work by interfering with the basic metabolic process of these pests while remaining safe for use around people and pets when used as recommended.
