Timbor

Timbor should only be applied for eradicating fungus off of wood and for protecting new wood from future infestation.  If you are 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.  

Timbor is an insecticide, fungicide and wood preservative for the protection and treatment of lumber against fungal decay and wood destroying insects. Timbor 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. Timbor does not treat mold or prevent mold from growing.


Active Ingredient: Disodium Octaborate Tetrahydrate
Target pests: Wood destroying organisms including: Termites, Beetles, Carpenter Ants
For use in: Interior and exterior as an insecticide, fungicide, or wood preservative. Use on untreated wood. 25# Timbor includes a scoop for easy measuring
Application: Can be used as a foam, liquid, or dust. If you already have a powderpost beetle infestion, BoraCare is the preferred product, especially for furniture, because it absorbs further into the wood to take care of the infestation. Timbor only absorbs 1/4 of an inch.
Yield: 1.5 pounds of Timbor will treat up to 200 sq. ft of untreated wood. Use as a dust against several insects. Refer to product label for complete details and instructions.

Timbor FAQ

What is Timbor?

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

What is the active ingredient in Timbor?

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.

    4 of 5 Stars  Small quantities not available
    By Laura on April 23, 2010

    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.

    5 of 5 Stars  Timbor DIY vs Commercial
    By Jeff on May 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!

    5 of 5 Stars  Good Stuf
    By Tim on October 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.

    5 of 5 Stars  Timbor
    By Russ on March 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

    5 of 5 Stars  Fast delivery and easy to use.
    By Harvey on July 3, 2014

    First, the delivery was super fast. My order arrived before I expected it. The product was easy to mix. I used warm (sun heated) water from a rain barrel. Fully mixed the powder 1/3 at a time using a paint mixer on my cordless drill. This seemed to be faster than adding all the powder at once and trying to disolve it in the water. The instructions indicate reserving part of the water until the powder is disolved. This worked well to finish the solution. There is a measuring scoop included. It measures 1/2 pound of product. So 15% solution in 1 gallon of water is 3 scoops. I used a chemical backpack sprayer that has a diaphram pump instead of a piston. Using a fan spray nozzle, the application went fairly quick. Time will tell if the product prevents the insects. I sprayed the entire wood frame of my house under construction. Stud walls, sheeting, trusses, floor joists. I plan to spray the wood siding before it goes up as well.

    By Mike on April 10, 2014

    I use this when ever I see black mold on wood when I'm repairing things on houses, if the wood is structurly sound, then I just treat it by mixing with water and spraying, then leave it in place, old school way was to remove ALL wood that had mold on it for fear of dry-rot, this product takes care of that problem. I have also used it as an insecticide in powder form by dusting affected areas, and as a permiter treatment on buildings for carpenter ants.

    By Danny on February 28, 2014
    Verified Purchase

    Time will tell as to effectiveness but the product mixes well and application is a breeze. However, DO NOT FREEZE! Being a salt, this product will solidify in cold temperatures, so use it soon after mixing. Do not let it rest in an unheated environment. If it solidifies you will have a BIG mess cleaning your sprayer.

  • 4 of 5 Stars  good product
    July 22, 2013

    We had some powder post larvae creating boring dust on a table on the top floor of an open room in converted dairy barn. The roof rafters are 30' long comprised of 5 lengths of 2x6. This problem seemed to be in only in a section of a few of the rafters and confined to the lower 10' section. The barn was build in 1942 with masonry walls. So I order this product, mixed and sprayed the it and no more problem as far as I can tell. I used the 15% solution for a one shot approach. Absorbs well into dry wood. Leaves perhaps some white residue but that's ok. The product will remain tacky if over spray lands on a surface that wouldn't allow for absorption. Like metal or OBS subfloor. It's a great product to have around a farm to treat wood as needed.

    5 of 5 Stars  My favorite Timbor supplier
    By Frank on May 29, 2013

    - is this company right here. I have been purchasing this product here for a few years, the price keeps getting better. And the product always arrives in good condition. As for the product, Timbor is the most cost-effective wood treatment for new wood construction there is - and it works! I have been intermittently building a home on a tropical island (which has the ground termite problem) for the last couple of years, and the lead carpenter has remarked how surprised he is that the termites seem to be leaving us alone, not something he is used to seeing.

    a lot less exspensive then boracare, Nicole was very helpful in suggesting this as an alternative to boracare, was easy to mix and apply. I'm using this as a preventative for drywood termites, only time will tell as to how well it works.

September 16, 2009 Aj asked:

QHow long does a Timbor treatment last? How often would a crawlspace need to be treated?

AThe 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.

August 13, 2009 Donna asked:

QWould I be able to spray Timbor on the wood myself or should I have a professional do the work?
The mold is under my house in the crawlspace. Is this a toxic chemical that would cause harm to pets if coming up through the floors or backyard wildlife?

ATimbor is not harmful to pets or wildlife.  In fact, this product and other wood treatment products like it are made from Borate, a natural occuring element in the earth.  However, this product will not kill mold, only wood destroying organisms like termites or beetles, and fungus.  Mold on wood can be treated with a product called Boracare with Moldcare. You can apply this product yourself. It s very important to read and follow the product label.

September 13, 2010 Carol asked:

QRecommended termite treatment(s)?
I have an 80 year old wood frame house set on piers over bare earth. I have had problems with drywood termites between the finish floor, subfloor and around the window frames. I have had the house tented twice. I would like to treat the house myself to get rid of any current activity and prevent against future activity. What products would you recommend? I have Timbor that I bought from you years ago, but I am wondering if I should plan on a more aggressive attack with another product?

ATimbor is a great product, but it does not penetrate or last as long as another product made by the same company called Bora-CareBora-Care is the best wood treatment product available because it penetrates all the way through a piece of wood where Timbor will only penetrate the outer coating.  If you have older wood then you should always use Bora-Care. Bora-Care will also stay in the wood forever, preventing any new infestations for years to come.

October 12, 2009 J.r. asked:

QHow often would I have to replenish the surface if I used Timbor on a log home?
The surface will be stained with a Behr siding product for sealing/staining purposes.

A

Timbor is more typically used on wood that will not be exposed to weathering and the outside.  You would need to re-apply the Timbor each time you re-sealed the wood with the Behr product.  The same company that makes Timbor makes a product called Bora-Care.  It is more expensive, but it is a liquid solution instead of a powder.  The Bora-Care will penetrate deeper in the wood, and protect the wood indefinitely so you would not have to re apply the product ever again.   Also, Bora-Care dries clear and is easier to paint or stain over whereas the Timbor leaves a white powder on the surface and is more difficult to paint or stain.
