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 in South Florida 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!

    5 of 5 stars  Good Stuf
    By Tim in San Diego, CA 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.

    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
    By Russ in Lawrence, KS 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

Looks like shipper tried to jury rig package with wrapping tape. Just a minor item that had no impact on application process. Will order some more to complete task in crawlspace.

    5 of 5 stars  Termite Killer & Protection
    By Mike in Diamond Bar, CA on 03/18/2016

    Highly recommend. I got tired of paying "professionals" for sub par termite treatment. National companies who did not drill completely through the concrete before injecting the treatment, another est. of $3,000 to replace a $40 fascia board & the company that drilled through the slab & didn't plug the holes before covering them, which allowed moisture intrusion to destroy the floor. Using information from DoMyOwnPestControl & the Timbor I ordered from them, I treated my property myself & have been termite free for the past 3-years. Reordered Timbor to retreat as a prevention measure. I have also helped family & neighbors with termite eradication using DoMyOwnPestControl.com.

    By Barry in New Orleans, LA on 12/02/2015

    By Laura in Durham, NC on 12/30/2014

    We have been using Timbor for over 15 years and it is the best product we have found in our 20 years of business. We use it on joists in basements and crawlspaces to prevent fungus/mold from regrowing when we install our systems. It has a proven track record and we will never use any other product as long as Timbor is available to us!

    5 of 5 stars  Log Cabin
    By Terry in Hemphill, Texas on 12/11/2014

    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

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.

QCan exterior house paint be applied over Timbor-treated wood?
Will a primer paint, such as Kilz, perform normally when applied to Timbor treated wood?

AAny primer or paint can safely be applied to Timbor treated wood as long as Timbor is completely dry after treatment and dry to the touch.  There should be no issues once it is completely dried.

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.

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.

QWhat is the different between BoraCare and Timbor? Both seem to be disodium octaborate tetrahydrate
Trying to kill powderpost beetles.

A

Bora-Care and Timbor are both borate products used to treat wood, but they could not be more different.  Timbor is in a powder form that is mixed with water.  It is much less expensive but it is intended more for protecting new wood only, or wood that you know does not have any issues.  Timbor will only penetrate the outer layer of the wood (about 1/4 inch) so it is more for protection or for treating fungus on the surface of the wood.

If you have an active infestation of termites, powder-post beetles or wood borers deep inside the wood then Timbor would not make it through the wood to kill these insects, up to 4 inches with one application or 8 with 2 appliations.  BoraCare is a liquid borate but has an additive, a glycol solution, which allows the product to penetrate through the entire piece of wood, therefore it should be used any time you have an active infestation because you are guaranteed it will kill anything in the wood no matter how deep it is.  Also, BoraCare will last forever in the wood so you will never have to worry about any infestations in the wood that you treat ever again.

QCan I treat raw lumber with Timbor to put on interior walls?
These walls will not be covered with anything.

A

Timbor can be applied to raw wood for the interior walls. Please refer to the product label for complete application instructions. If the wood will remain exposed as decorative structural wood, then you may want to use Boracare instead of Timbor; Timbor sometimes will†dry with a visibly white texture that may not be as appealing in living spaces. It is also much easier to apply stain, paint, or sealant after applying Boracare.

QCan I use same applicator for Timbor and Termidor SC if I clean it well between uses?

A

You could potentially use the same sprayer to apply Timbor and Termidor SC if it were cleaned and allowed to dry completely between product uses. It is best to use a dedicated sprayer to apply non-repellent insecticides such as Termidor SC to avoid contaminating the insecticide. You could also use a tank cleaner such as Neutralize Spray Tank Cleaner and Neutralizer†to reduce the risk of contaminating products.

QWhat type of respiratory or other protective equipment should be used when applying Tim-bor?
When applying Timbor under an open wood deck with good ventilation should a specific type of protective mask and clothing be used?

A

Timbor is actually odorless so you don't necessarily have to wear a protective mask but if you desire to do so anyway, we†would recommend using an N95 Valved Respiratory Mask.

I have several big reclaimed fir (I think) beams going up on the inside of a new home. Can I put something like a clear finish over them after treating with Timbor, after it has dried completely?

A

Yes, it is recommended that you use a finish and/or sealant after using Timbor. It will potentially dry with a texture so you may have to sand it first.

QCan 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.

QCan Timbor be airialized as a mist or fogger?
I have had my foundation crawl space Joyce treated in the past to re-mediate mold. The contractor sprays it as a wet solution over everything Joyce insulation piling etc. Then the insulation is wet which causes it to fall Daaaaa really.

A

Timbor is a wettable powder and as such is not labeled to be fogged. Timbor will clog all foggers because it never truly goes into a solution but instead just goes into a suspension. Please take a few minutes to read the Timbor product label so you can see all of the ways it is labeled to be applied. Please provide additional information on the targeted insect so that we can assist you further. We are always happy to help!

QWhat is the approximate drying time for Tim-bor?
