It is a water-soluble borate powder that can be applied as a dust, spray, foam or mist onto wood and cellulosic materials or inside wall voids, cracks and crevices.

The dust provides an additional layer of protection by killing carpenter ants, drywood alates and adult wood boring beetles that enter the structure and pass through it. A Nisus Corp product.
