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.



Product Documents


Timbor can be used as a Dust, Liquid, or Foam. It is water soluble, economical, odorless and can be used in conjnction with fumigation for residual protection. It is formulated with a concern for the environment.

Timbor is only absorbed 1/4 inch into the wood and leaves a white powdery coating. If you are treating thick wood or want it to look like its original state, then purchase the BoraCare product.

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.

    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

    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

    By Mike in prairieville,la on 06/27/2012

    Two years ago, I bought a camp that has alot of rough cut lumber. Early summer I noticed the powder post exodus, and bought a pail of timbor. Last year I noticed considerably less activity and this year I have seen a few. I believe this stuff works, just wish I was there to apply it when the camp was built.

    By Elmer in Eugene, OR on 09/02/2011
    Verified Purchase

    Had to rebuild a deck/balcony that had gotten rotten despite treatment with a variety of products. Treated the new wood with Timbor. Mixing and application, garden sprayer, went well. Seemed to soak in well. Took stain well. Time will tell whether or not it works better then the other treatments I have tried. I expect good results.

    4 of 5 stars  First time user of Timbor
    By Ivan in Concord, CA on 07/29/2011

    This is my first use of Timbor so I can only talk about the application and not how effective it is yet. Using it for Powder Post Beetles and possible other bugs in hardwood chunks I'm keeping for fine woodworking projects. they have current holes and I hope Timbor will kill them when they come out or try to go back in. Mixing Timbor was simple and I didn't have any problems with mixing it in warm water. I made up small batches at a time and used a brush to apply. No odor and it is colorless, except that it left a very faint silverly sheen to the wood after drying if you held it up to the sun. I am keeping an eye on the wood to see if Timbor will take care of my pests.

    2 of 5 stars  Difficult to spray
    By Frank in Elk, CA on 06/06/2011

    I'm using Timbor to prevent powder post beetles from infecting newly milled hardwoods. The powder is very difficult to mix well enough into water to go through the sprayer nozzle. Wish they made a liquid concentrate. The sprayer clogs with small unmixed pieces of powder. It's impossible to mix it enough to get it completely dissolved. I even tried mixing it in small quantities in a kitchen blender. If you leave the mixture in the sprayer overnight, powder particles precipitate and clog the nozzle. I can't review its effectiveness as a pesticide, I won't know for a while.

    By Ken in South Padre Island, Texas on 02/17/2011

    I just used this product yesterday. Mixing was very easy. I did break down the quantity and mixed only a quart of liquid. Application was smooth. I did add a drop of dish soap to help as a spreader. Now I just have to wait and see if I got the little bugs. I imagine I may not know for at least 6 months if I got them.

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.

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.

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.

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.

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.

QIs the remaining "powder" harmful?
I recently had timber applied to my attic. The access was through a pantry. Is the white "powder" residue left behind harmful?

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. 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.

QCan Timbor be applied with a sponge or hand-pump sprayer?
I have a small cellar and would like to apply Timbor to the ceiling without having to buy or rent a tank and hose sprayer. Thank you.

ATimbor can be applied with a paint brush or a gallon pump sprayer. To create a 15% solution, mix 1.5 pounds of Timbor to one gallon of water. This solution ratio ensures that only one application needs to be performed. Please be sure to read the Timbor Product Label before use for complete instructions.

QHow long does it take Timbor to kill the bugs that have infected my wood? It will be used to build furniture.

ADepending on thickness of the wood, Timbor can take up to 30 days or more to completely kill the insects inside the wood.  However, it will only kill beetles that are active since Timbor kills the insects when they eat the wood, they ingest the Timbor at the same time.  Beetles can remain dormant for years, and so if some beetles are dormant now, they will not die.  They will not die until they become active and begin eating again.

QTo stop existing wood rot, will flooding it with Tim-Bor stop it or must I use Bora-care?
Do you have a product that treats fence posts?

ABora-Care is the best product for treating wood by far.  If you have existing wood rot then you definitely want to apply Bora-Care because it penetrates deeper than Timbor and will have a better chance at stopping the progression of the wood rot.

QHow much Timbor should I spray over the wood to be treated is enough? Can I apply either too much or too little?

AYou only need to apply the Timbor solution so the wood is wet.  You should not apply the product so it starts to drip and runoff, that is too much.  Just enough to wet the surface and evenly coat all exposed sides of the wood, like you are spray painting it.

QI have a house made of Douglas Fir. I treated it 9 years ago with Timbor. When do I retreat the house?

AIf you have sealed the outside of the house, then Timbor can stay in the wood a very long time; sometimes 20 years or more.  If the house has not been sealed or protected lately, then it would probably be time to treat again.  The treatment will last longer after you apply it if it is sealed and protected.

QWould you recommend Timbor or Bora-Care?
I recently had my house treated due to termite infestation. After they finished treating my house, the inspector said he noticed some fungus on some of the floor joist's and recommended me using Timbor. With no signs of any infestation, and assuming that their treatment took care of the termites, would you recommend Timbor or Bora-Care?

ATimbor is perfectly fine for treating fungus because fungus is a growth on the surface of the wood.  Timbor only really is for protecting new wood that you know does not have any issues or wood that you only need to treat the surface for because Timbor will not penetrate very deep into the wood.  However, what you want to be sure of is that the growth is in fact fungus, and not mold.  Timbor or Bora-Care will not treat mold, so you would want to purchase Bora-Care with Mold Care if in fact it was mold.

ATimbor is a wood treatment product that is mixed with water in a one gallon sprayer and applied to raw, untreated, unsealed, unpainted wood.  It can be used on any raw wood anywhere in the house.  Timbor is made from the element Borate, which is a natural occuring element in the earth.  It is very safe and non-toxic.  Timbor will last for years on the shelf as long as it is not exposed to moisture or water.
