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.

    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!

    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  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  Log Cabin
    By Terry on December 11, 2014

    My Grandson and I built a log cabin. We wanted to protect it against wood boring insects. Timbor was recommended. We sprayed the wood with Timbor and saw no sign of wood boring insects. We bought the large pail of Timbor, and since the cabin was all wood, we sprayed the sills, joysts, floor, top and underneath. We sprayed the log walls, inside and out, also the rafters and lathe. We enjoyed the cabin for a couple of years, but unfortunately, it recently burned from a fire started by an unattended wood heater. We are in the process of building another log cabin in the same spot. One thing for sure, we will not be careless with the fire. Also, we plan on protecting the cabin from wood eating pests by spraying it with Timbor. Sincerely, Terry McGraw

  • 5 of 5 Stars  Timbor-25 lb
    By Wayne on November 13, 2014

    Performed as expected. The powder easily disolved in water and worked well with a standard sprayer; although over time it tended to clog up the sprayer controls. I had to take the sprayer apart and clean the "workings". The spray seemed to absorb well into the logs; it is still too early to tell how effective it will be in controling insect infestations. The 25lb bucket comes with a 1/2 lb measuring scoop which is helpful if you don't have a weighing scale handy. One minor annoyance is that the sealed lid on the plastic bucket is rather difficult to remove from the bucket. It is the same with all similarly designed buckets and lids--it requires some considerable effort.

    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.

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.

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.

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.

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.

November 13, 2014 Randy from Ottawa, Il. asked:

QCan I use Timbor on firewood that will be burned in the house

A No, you would not want to burn any wood that has been treated with Timbor or any other insecticide. The manufacturers do not recommend this. Any insecticide should not be breathed in, and when burned these toxins can become airborne. It would be suggested to not burn the wood.

QI am in NY state-can't buy Timbor -what major chain stores sell it if I buy it in a different state

A Currently, the State of New York restricts shipment of all termiticides, such as Timbor, to your state so it would not be available to homeowners at local stores and we are not aware of what stores in other states would carry.  We do offer free shipping to anywhere in the continental US so would be able to ship to another state for you.

QIndoor use
I want to use the timbor on a 130 yr old barn beam that I will convert to a mantle. I plan on spraying it with timbor, letting it dry, sanding lightly, then sealing it with Tung oil. Is the Timbor safe to have in a home? The mantle will be over a working fireplace. Is heat a problem?

A Yes, Timbor is meant to be used on indoor areas that will not be exposed to the elements. Timbor should only be applied for eradicating fungus off of wood and for protecting new wood from future infestation. Heat should not be a problem once the product is dried and sealed within the wood. Be aware that Timbor does only absorb 1/4 of an inch into the wood. If you are looking for something to penetrate the wood and last for the lifetime of the wood, we would recommend Boracare. Please let us know if you have any additional questions.

QTimBor & Boracare Use?: I have termites in a brand new build, near French doors.
I intend to use Boracare on first 2 feet, but exterminator told me that termites would walk right over it and go to untreated wood. Do I need to use Boracare on ALL wood, or can I use Boracare on first 2 feet and Timbor on the rest?

A

Boracare is preferred over other treatments such as Timbor in new constuction and raw untreated wood because Boracare will absorb into the entire piece of wood when applied to all accessible areas where Timbor only absorbs 1/4 inch into the wood. Please refer to the product label for further info.

A Timbor 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. It should not be harmful to you or your family either through skin contact - though we would recommend refraining from touching your eyes or injesting it if you have gotten some on your hands or skin. Simply wash it off with soap and water.
