Product Overview

Tim-bor Professional should only be applied for eradicating fungus off of wood and for protecting new wood from future infestation.  If treating any wood with an existing infestation, you should always use Bora-Care. Bora-Care will penetrate through an entire piece of wood much deeper and ensure proper control, and it will protect the wood you are treating forever.

Tim-bor Professional is an insecticide, fungicide and wood preservative for the protection and treatment of lumber against fungal decay and wood destroying insects. Tim-bor is a water soluble, inorganic borate salt with insecticidal and fungicidal properties. It is an effective treatment for wood to kill and prevent infestations of decay fungi including white rot, brown rot (i.e. Poria) and wet rots. Tim-bor does not treat mold or prevent mold from growing.

What is Timbor?

Timbor is a wood preservative that works as an insecticide and fungicide.

The active ingredient in Timbor is disodium octaborate tetrahydrate, a natural borate compound.

What is a borate compound?

Borate compounds are derived from mineral deposits that contain the element Boron. These compounds are use in the production of many products including ceramics, glass and medicines and also work extremely well as insecticides and fungicides.

Why is Timbor considered an insecticide and fungicide?

Insects are exposed to the active ingredient by eating treated wood or by ingestion while grooming. Borates are a contact toxicant to fungi. The borates prevent metabolism of food by insects and fungi causing death.

How is Timbor applied?

Timbor is applied to the surface of bare wood as a liquid. It can also be applied as a dust into void attic and wall void areas for labeled insect control.

How does Timbor work as a wood preservative?

When Timbor is applied as a liquid to the surface of bare wood, it diffuses into the wood to make the wood itself toxic to wood destroying organisms such as wood decay fungus or drywood termites.

Is Timbor concentrate a liquid?

Timbor comes in a powder form that is used as a powder or mixed with water to form a liquid solution. To create a 10% solution mix one pound of Timbor to one gallon of water. This solution must be applied twice to a bare wood surface. To create a 15% solution, mix 1.5 pounds of Timbor to one gallon of water. This solution can be applied only once to the wood surface.

Is Timbor labeled to treat wood decay fungus?

Timbor is labeled for the control and prevention of wood decay fungi including white rot, brown rot, poria and wet rots.

Is Timbor labeled for the control of carpenter ants?

Timbor is labeled for the control and prevention of carpenter ants by applying Timbor dust into active ant galleries and into areas where ants may enter the structure.

What wood destroying organisms is Timbor labeled to control?

Timbor is labeled for the control and prevention of drywood termites, wood destroying beetles, wood decay fungi, carpenter ants and termites.

Can Timbor be foamed?

Timbor can be foamed using equipment designed for foaming applications. Foaming requires a 15% solution in conjunction with a foaming agent. A dry foam is recommended for best results.

Does Timbor affect ornamental plants?

Yes, over spray on plants or spills near the plant roots can kill or retard plant growth.

    Timbor DIY vs Commercial

    By Jeff on 05/28/2011

    A national chain quoted me $2,900 to spray the trusses of my new home under construction. I paid about $65 for the Timbor and spent about 4 hours spraying. Absolutely worth it!

    Timbor

    By Russ on 03/14/2011

    Easy to use, included measuring cup, just added to water in a separate 5 gallon pail and agitated with a drill and paint mixer, pour into pump up sprayer and saturated walls of older garage. I sprayed twice waiting about 30 minutes between application, for good penetration, had it been spring or summer I might have made several wet on wet applications as the wood was old and dry. I purchased the 25 pound pail and have several more structures to treat. My (former thanks to DMOPC) pest control person said that Timbor was a great low cost addition to a complete termite treatment. I also note that Timbor is especially good at repelling carpenter ants, and fungus which I believe is the cause of dry rot. Thanks DMOPC

    Good Stuf

    By Tim on 10/18/2010

    The price at DoMyOwnPestControl was better than I could find elsewhere and their support was great. This stuff (borate minerals) has been around a million years and is known to make wood toxic most insects including drywood termites, carpenter ants, ants and wood destroying fungi. It works by dehydrating them. It doesn't kill subterrainian termites, but those are easier to find by inspection (mud tubes). It is as advertised and, applied properly will work. I had drywood termites and ants crawling all over the structure before treating the outside with this stuff and now they are all dead, gone and discouraged. I've covered up the outside wood (siding, shingles, etc.) and so long as the cover remains intact, this stuff will continue to do its job.

    Small quantities not available

    By Laura on 04/23/2010

    Verified Purchase

    Product was easily mixed. Would have preferred directions for mixing smaller quantities on package. Might use BoraCare next time for effectiveness but small quantities of that were not available and it was costly.

Q
How long does a Timbor treatment last? How often would a crawlspace need to be treated?
A
The manufacturer states that Timbor will last for the life of the wood as long as the wood is not exposed to rain or flooding.  It will stay in the wood forever because of how it bonds to the cells of the wood.

Q
After the application of Timbor on the interior of building, does it need to be painted?
A

It is recommended that you use a sealant or paint on the wood treated with Timbor. This will seal the product into the wood so that it will last for the life of the wood. It is not necessary to paint or use a sealant though.

Q
Can I mix Timbor with a glycol solution instead of water for deeper wood penetration?
A
No, Timbor cannot be mixed with anything else besides water. If you do mix it with other products, it will clump and not work the way you would like it to.

Q
Can I mix a small amount of Timbor for injecting into holes with an injector needle?

I would like to mix a small amount for hole injection. I have a log home and have been trying to treat the holes, but I would like to mix small amounts for injection with a small injection type needle.

A

Timbor should only be mixed and applied according to the product label. Because of the formulation, the Timbor solution would most likely clog any type of small applicator you would try to use. Jecta is a ready-to-use borate wood treatment that can be applied to specific areas.

Q
Is Timbor effective when applied in soil near footings and under buildings?
A

Timbor is a wood treatment product only and would not be effective at all in soil. If you want to treat soil to protect against wood destroying insects like termites you would need to use something like Taurus SC in a trench application.  We have a guide on how to use it here.

Q
I have some old stain on the wood I'd like to protect. Why can I not use Timbor right over the old stain?
A
Timbor is a wood preservative that need to able to penetrate and be absorbed into the wood. If there is a stain, pain, or any type of sealant then the Timbor will not be able to penetrate thus making it ineffective. Any finish that has been applied to wood should be sanded off so that you can apply the Timbor for it to be effective. However, if you are wishing to restain the wood then BoraCare would be a better product because BoraCare dries completely clear whereas Timbor leaves a powdery white film.
