Nisus' mission is to offer quality, sustainable pest control and wood preservative products to industry professionals while p ... roviding the lowest possible impact to the environment. Many of our products use borate as an active ingredient. Borates are mineral salts that are mined from the earth and while they are deadly to insect pests, they have extremely low mammalian toxicity and pose minimal risk to people, pets and the environment. In our wood preservation division, we manufacture copper naphthenate under the QNAP® brand and a Disodium Octaborate Tetrahydrate (DOT) borate wood preservative under the Cellutreat® brand. QNAP can be used as a stand-alone or as a dual treatment with Cellutreat. Cellutreat can be used as a dual treatment with QNAP or creosote. Both are EPA-registered “general use” preservatives and standardized by the American Wood Protection Association (AWPA). read more
