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.

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.

Small quantities not available
By Laura on April 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.

Timbor DIY vs Commercial
By Jeff on May 28, 2011A 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!

Good Stuf
By Tim on October 18, 2010The 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.

Timbor
By Russ on March 14, 2011Easy 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

Adding Timbor during reconstruction
By Luanne on January 29, 2013A downstairs flood required the subflooring be removed and replaced. While the rafters were open I sprayed all the exposed wood with a 15% Timbor solution. My order arrived promptly and accurately. It was easy to measure thanks to the included measuring scoop, easy to mix and easy to spray. I wore protective clothing as advised, but felt comfortable since it is not toxic to humans or pets. The plywood for the subflooring will be delivered a couple of days before it is needed to allow me time to treat that also. I feel good knowing that I've done something proactive to prevent a termite infestation without the harmful side efffects of a potent pesticide.

Always timely
By Cynthia on December 30, 2012You ship immediately. I will have to let you know in several years how good the product is, but I'm betting on you. My biggest problem is that the borate liquid weighs a lot, I need a lot to treat untreated pine in an insect rich environment and I am limited on my baggage weight!! I guess a good problem to have. Thanks

Usefull stuff
By Riley on December 20, 2012I used this stuff many years ago on a log house. A permanant treatment for wood. Also good as flux for forge welding. I also mix it with a lotion for my feet. Really cleared up my feet. Very safe. Just consider that a borax solution is used on the eyes of babies, but that solution should come from your doctor.

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. Would I be able to spray Timbor on the wood myself or should I have a professional do the work? 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.

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-Care. Bora-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 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.

Joerg from West Point Va. asked:
QCan Timbor also be used to treat black mold growing on wood surfaces?
ATimbor is not labeled to treat mold at all and will not work for this use. Boracare with Moldcare is the only product that we carry for treating mold on bare wood. Boracare with Moldcare will kill the mold spore but you will need to use a product such as Mold-Clean prior to apply Boracare with Moldcare to remove the mold stain.

Richard from Baker City, Or asked:
QReplacing bridge timbers. What would be best to use? This product not to be exposed to rain?
ATimbor is meant to be used on indoor areas that will not be exposed to the elements. Boracare would be a better choice for bridge timbers but the wood must be sealed after the application with paint, stain or wood sealer.

J from Redwood City Ca asked:
QIs timbor effective at killing silverfish? Also,is it ok to paint over plywood after treatment with timbor?
I asked about silverfish because after spraying the cracks of my garage framing,I noticed the silverfish running out of the cracks.
ATimbor is not actually labeled for silverfish though it may actually eliminate silverfish that come into contact with treated areas. Any primer or paint can be applied to Timbor treated wood as long as the Timbor application is completely dry to the touch.

Rob from Brevard, Nc asked:
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.

Karl from Arlee, Montana asked:
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.

April 12, 2011 Gina asked:
QI was taught to use Timbor for roach and German roach control, any guarantee that it works for these pests?
ANo. Timbor is not labeled for roach control and would not be the best choice for this type of application. If you have a current infestation of roaches we recommend the products that come in our Roach Kit #2. The products in the Roach Control Kit #2 are perfect for most roach control problems in most indoor settings. This professional kit includes Demon WP Insecticide for spraying the outside perimeter of the home and inside underneath appliances, behind cabinets, under toilets and sinks, etc. Advion Roach Bait Gel--one of the best roach baits on the market. Advion can be applied up high in the kitchen in the corner of cabinets and in cracks and crevices in kitchens and bathrooms. The bait contains a slow-acting poison that attracts and kills feeding roaches, who also spread the bait to other roaches by contact or by sharing food. Finally, Gentrol Point Source stations provide an IGR (Insect Growth Regulator) that will stop roaches from laying eggs, helping to halt the infestation. The combination of an IGR with roach bait is a highly effective roach control strategy that is widely used by pest control professionals.

April 10, 2011 Jose asked:
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.

May 25, 2010 Margrey asked:
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.

March 18, 2010 Robert asked:
QWould you recommend Timbor or Boracare?
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 Boracare?
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.
