Formulated with a concern for the environment, Tim-bor is used for the control of wood boring beetles (common borer, two tooth, magnum borer, powder post and pinhole borers) drywood termites and wood decay fungi. As water soluble borate powder, Tim-bor diffuses into the wood and acts as a wood insecticide, fungicide and preservative. Tim-bor won’t break down over time like most organic compounds, therefore offering longer lasting protection. Best of all, Tim-bor is virtually odorless and has no known resistance.

Tim-bor is a natural insecticide and fungicide that is widely used as wood preservative and protectant. It is composed of nearly pure sodium borate, a mined crystalline form of boron with comes from the earth itself.

The manufacturer (US Borax) states that Tim-bor will last for the life of the wood as long as the wood is not exposed water flooding.  It will stay in the wood for decades because of how it bonds to the cells of the wood.

  • Prevents and controls drywood termites, wood decay fungi, carpenter ants, old house borers and powderpost beetles.
  • Won’t discolor or stain wood surfaces
  • Won’t corrode screws, nails and other components used in construction
  • Virtually odorless
  • Can be used indoors and outdoors
  • Manufactured with a concern for the environment

How Does Timbor Work ?

Tim-bor is a wood preservative that stops and prevents rot and insect borers. It can be sprayed or brushed onto the surface of lumber, timbers, OSB or plywood. The preservative becomes a part of the wood as it penetrates deep into the wood through a process called diffusion. By diffusing deep into wood fibers, Tim-bor lasts for as long as wood is kept away from flowing water. That means that Timbor has controlling powers that last for a very long time.

How does our Tim-bor treatment work on wood borers inside your house structure (All species of NZ borers).

Tim-bor treated wood also deters wood destroying Beetle larvae.  Eggs deposited on the surface of treated wood by borer beetles will have a reduced hatch rate. Larvae that may hatch from eggs will soon die after attempting to eat into Tim-bor treated wood. In infested wood, the larvae will die from ingesting Tim-bor treated wood as they tunnel toward the surface of the wood to pupate. Depending on the life cycle of the beetle, type of beetle, and seasonality of treatment, adult beetles may emerge but will not re-infest the wood.

Wood treatment designed for maximum solubility

Tim-bor® is a high-performance borate wood preservative that has been specially designed to provide the highest concentration of boron at the maximum possible solubility and rate of dissolution in water.  Wood treated with Tim-bor can be used for a variety of purposes, such as floor joists and bearers, floorboards, trussed rafters, studding, cladding, and exterior joinery.

As a wood protectant, borate products such as Tim-bor® Industrial are highly effective broad-spectrum wood preservatives that enable full control over moisture-induced decay and fungi such as wood rot. And they eliminate protect both solid wood and engineered wood products from pests such as termites, carpenter ants, and wood-boring beetles.

Timbor is imported as a water soluble powder in 25kg bags. 1.5kg bag makes 10 litres of working solution (15% solution). Timbor is applied with a commercial pump sprayer, and requires the mix to be reticulated during the application process to keep the boron mixed correctly, see label instructions. The dry powder can also be used to treat wall voids for borer and ants.

Like other borate-based wood preservatives, Timbor is generally not available in stores and we are the only borer treatment company in NZ using Tim-bor.

This product is not sold or available in 10kg anymore in NZ.
