Insecticide and Fungicide

Tim-bor is an effective treatment for wood (and wood-foam composite structural components) to kill and prevent infestations of decay fungi including white rot, brown rot (i.e. Poria) and wet rots. Tim-bor is also effective for the prevention and control of wood destroying insects such as, but not limited to the following organisms:

  • Subterranean Termites
  • Drywood Termites
  • Dampwood Termites
  • Powderpost Beetles
  • "False" Powderpost Beetles
  • Deathwatch and Furniture Beetles
  • Old House Borers, Longhorn Beetles
  • Carpenter Ants
  • Bark and Timber Beetles

Tim-bor can be applied as a solution, foam or dust for wood treatment against wood destroying organisms and as a solution or dust for general insect control. Tim-bor, applied as a solution or foam to wood, will penetrate into the wood to various depths dependent on the moisture in the wood and the wood species. The active ingredient does not break down, therefore as normal moisture changes occur in the wood, Tim-bor is always available to be drawn deeper into the wood over time, providing long lasting protection. When used as a dust or as a crack and crevice solution, Tim-bor is not repellent to general pests.

The mode of action for Tim-bor is that of a slow acting stomach poison to insects and a contact poison to decay fungi. As wood destroying insects or their larvae feed on, tunnel in and/or digest wood, they accumulate the active ingredient into their systems. General insects such as cockroaches, ants, crickets, etc. will ingest Tim-bor through their normal preening habits after contacting deposits. The accumulation of the boron into their systems acts to poison the insect.

Tim-bor is also active against other general pests like cockroaches, ants, silverfish, earwigs, and crickets. Tim-bor powder can be applied directly to insect harborage areas or in solution as a crack and crevice application. When the insect crawls over treated areas, the tiny particles of powder adhere to the insect's body. Tim-bor is ingested as the insect attempts to clean the powder from its legs and antennae.

Area covered by Tim-Bor = 5 gal per 1000 sq ft of wood surface. (at 10% solution, 1 lb per gallon of water / at 15% solution 1.5 lb per gallon of water)

  • How To Apply and Use TIM-BOR Wood Preservative


Tim-bor Professional is a fast and efficient way to treat a structure for target pests. It can be used as a wood preservative, fungicide and insecticide on its own or in conjunction with other treatments as a supplement. Because of its application flexibility as a dust or liquid, you can apply it as a dust, spray, foam or mist onto wood and cellulose building materials or inside wall voids, cracks and crevices. The active ingredient in Tim-bor Professional is a natural borate mineral salt with a low mammalian toxicity. How To Apply and Use TIM-BOR Wood Preservative



Tim-bor Professional’s active ingredient is Disodium Octaborate Tetrahydrate (DOT), a natural borate mineral salt and micronutrient. It is manufactured for use in the form of a water-soluble borate powder. Once it’s applied in a liquid form by foaming, misting or spraying onto wood or other cellulosic materials, the borate active ingredient creates a protective envelope and remains for years of protection. Often Tim-bor Professional is dusted into places like wall voids where pests like to hide as an additional protection against carpenter ants, drywood termite, and adult wood boring beetles. When the dust gets on the insects, they clean themselves and consume the boron during the cleaning process. How To Apply and Use TIM-BOR Wood Preservative



DOT is a natural form of elemental boron, which is essential for the healthy growth of plants and believed important in human calcium metabolism. Because animals and humans simply take what they need from their diet and rapidly excrete any excess via the kidneys, DOT has a low acute toxicity. As a result, Tim-bor Professional is about half as toxic as sodium chloride or table salt (in a laboratory setting), but very effective against insects and fungi that do not have the same excretion mechanisms.

DOT maximizes the solubility, the rate of dissolution and the boric oxide content to give a borate active ingredient far superior to traditional boric acid or borax. At the levels used in Tim-bor Professional applications, it prevents pest infestation by inhibiting pest metabolism on a cellular basis. The tetrahydroxyborate anion forms a chelate complex with the cis-adjacent hydroxyl groups in the ribose sugar of nicotinamide adenine dinucleotide (NAD), with the cationic nitrogen of the nicotinamide moiety providing electrostatic stabilization of the chelate. In this configuration, NAD and NADP cannot be used by the dehydrogenase enzymes of glycolysis, the pentose phosphate pathway or the tricarboxylic acid pathway, and so the cellular energy generating mechanisms, including adenosine triphosphate production, are shut down.
