Timbor Professional's active ingredient, 98% Disodium Octaborate Tetrahydrate has no known insect resistance. It may used as as a liquid, foam or dust, and provides long term protection against insects(drywood and subterranean termites, wood boring beetles, carpenter ants and decaying fungi.
How Does Timbor Work ?
Tim-bor is a wood preservative that stops and prevents rot and insect attacks. It can be sprayed or brushed onto the surface of lumber, timbers, OSB or plywood. The preservative becomes a part of the wood as it penetrates deep into the wood through a process called diffusion. By diffusing deep into wood fibers, Tim-bor lasts for as long as wood is kept away from flowing water. That means that Timbor has controlling powers that last for a very long time.
Used For Wood Destroying Insects & Decay Fungi
Timbor is not only an insecticide that provides protection and treatment of lumber from wood destroying insects, but also works against fungal decay. This fungal decay includes, brown rot, white rot and wet rots. Timbor is a water soluble, inorganic borate salt with insecticidal properties effective against wood-destoying organisms, including, Subterranean termites, Dry wood termites, Damp wood termites, Carpenter ants, PowderPost Beetles (False PowderPost Beetles, Furniture and Deathwatch Beetles, Old House Borers, Longhorn Beetles, and Ambrosia Beetles.). Timbor does not treat mold or prevent mold from growing.
Types of Applications
Tim-bor can be applied as a solution, foam or dust for wood treatment against wood destroying organisms and as a solution or dust for general insect control. Tim-bor, applied as a solution or foam to wood, will penetrate into the wood to various depths dependent upon the moisture in the wood and the wood species. The active ingredient in Tim-bor does not break down. As normal moisture changes occur in the wood, Tim-bor is always available to be drawn deeper into the wood over time, providing long lasting protection. The mode of action for Timbor is that of a slow acting stomach poison to insects, and a contact poison to decay fungi. As Wood-destroying insects or their larvae feed on, tunnel in and/or digest wood, they accumulate the active ingredient of Timbor into their systems
Timbor - Solution For Long-Term Protection
Timbor is a small investment for your home and key in preventing fungus and termite infestations with one or several applications. Treat your home to Timbor, and you'll be treating yourself to a longer-lasting cure for insect and decay problems.
- Timbor is wood preservative that works as an insecticide and fungicide.
- Timbor is a borate compound(Disodium Octaborate Tetrahydrate ). Borate compounds are derived from mineral deposits that contain the element Boron.
- Timbor is both an insecticide and a 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.
- Tim-bor can be applied to the surface of bare wood. Tim-bor can be foamed using equipment designed for foaming applications It can also be applied as a dust into void attic and wall void areas for labeled insect control.
- Timbor mixes with water to make a 10% solution or a 15% solution; use 1lb or 1.5 lb per gallon of water.
- Won't stain or discolor wood surfaces.
- Virtually odorless
- Will not corrode screws, nails and other components used in construction.
- Boracare ( Another borate ) allows a deeper absorbion and penetration in wood. If you have powderpost beetles, particulary in furniture, Boracare may be a preferred product. Timbor only absorbs to an 1/4 of an inch.

General Insects and Timbor Insecticide
General insects such as cockroaches, ants, crickets, etc. will ingest Timbor through their normal preening habits after contacting deposits. The accumulation of the boron into their systems acts to poison the insect. When used as a dust or as a crack and crevice solution, Timbor is not repellent to general pests. Since Timbor is slow-acting, termites that have fed on treated wood can accumulate the active ingredient and still move among other individuals in the colony. The transfer of food from workers to nymphs, soldiers and reproductives, will also transfer the ingested Tim-bor. Affected individuals also exhibit behavioral changes, becoming sluggish, stop feeding and become moribund. Others in the colony will avoid these individuals as well as areas where these individuals have died. The Timbor treated wood is not the first choice for feeding; therefore foraging termites avoid Tim-bor treated wood. In addition, the Timbor powder used as a dust in wall voids and injected into galleries is toxic to termites.
Timbor and Powderpost Beetle Larvae
Timbor treated wood also deters wood destroying Beetle larvae. Eggs deposited on the surface of treated wood by beetles will have a reduced hatch rate. Larvae that may hatch from eggs will soon die after attempting to eat into Timbor treated wood. In infested wood, the larvae will die from ingesting Timbor treated wood as they tunnel toward the surface of the wood to pupate. Depending on the life cycle of the beetle, type of beetle, and seasonality of treatment, adult beetles may emerge but will not re infest the wood.
Tim-bor and Carpenter Ants
Carpenter Ants do not consume wood, but they can cause substantial and rapid damage by excavating cavities in wood for nesting. Timbor treated wood is very unpalatable and is not excavated by carpenter ants. Treated wood with Tim-bor alone may not prevent or eliminate a carpenter ant infestation since the ants can penetrate construction features and avoid chewing treated wood. However, Timbor powder used as a dust in nesting sites, in wood and in wall voids and around conduit and plumbing will control these pests. The Timbor powder adheres to the carpenter ant's body and is ingested as the insect attempts to clean the powder off.

Timbor Remedial & Preventative Treatments
Basement or crawl space
Spray Tim-bor solution on all bare wood accessible in the flooring and subfloor. This application will control an infestation even when certain parts of a gallery are not directly sprayed. In addition, steps must be taken to correct moisture problems (leaks, etc.) that may have led to and sustained the infestation.
Spray Timbor solutions to all accessible wood: rafters, trusses, top-plates, ceiling joists, plywood, particle board, OSB etc. Accessible areas with known infestations should be drilled and injected depending on the type of infestation. This has been a particularly effective technique in spot treating for control of drywood termites.
Timbor can be applied to bare siding, trim or logs. Applications can be made by spray or pressure injection techniques. Painted or sealed wood can be treated by pressure injection with this solution, or the sealing coat can be removed prior to application. Following treatment, the exterior wood should be sealed to protect Tim-bor from diffusing out. Wood should be completely dry (at least 48 hours) before a sealing coat (paint, varnish or waterproofing seal) can be applied. When properly applied, Tim-bor will not interfere with application of a deck treatment.
Tim-bor can be used to treat wood decks. Prepare the deck by removing any dirt, debris or sealant that will interfere with the application and absorption of Timbor. After the deck has dried (dry to the touch, no standing puddles), 2 applications of 10% or 1 application of 15% Timbor can then be applied to the wood. Protect any surrounding plants and ornamentals from accidental contact with the solution. Following treatment, the deck should be sealed with a water-repellent preservative product to protect the Tim-bor from diffusing out. Wood should be allowed to dry before a sealing coat can be applied.
Yield 1.5 pounds of Timbor will treat up to 200 sq. ft of untreated wood. Refer to product label for complete instructions. Mixture|Application 1 lb = 10% solution, 1.5 lb= 15% solution Application
- Always estimate the amount of Timbor solution needed. Approximately 1 gallon of mixed solution will be needed to treat 200 square feet of wood surface area. Timbor can be applied as a 10% solution or 15% solution.
- Using a slightly oversized container/bucket, fill with water to about 80% of the final required volume. To prepare a 10% Tim-bor solution, add 1 lb Tim-bor powder per gallon of water, then add the remainder of the water, agitating until the Timbor has dissolved. To prepare a 15% solution, add 1.5 lb per gallon of water.
Wood application procedures
- Spray TimBor: The Tim-bor solutions or foam should be applied evenly to wood using a medium to coarse spray at low pressures (20-30 psi). Application rate is 1 gallon per 200 square feet of wood surface area. Ensure that all accessible wood surfaces are thoroughly wetted. Wood will absorb Tim-bor solution at different rates. Surfaces that absorb solution rapidly can be re sprayed immediately.
- Foam: Prepare a 15% solution as listed above and add foaming agent. Typically 1-2 ounces of a foaming agentadded to the 15% solution will produce a dry foam with the desired expansion ratios of approximately 20 to 1 (Approx. 20 gallons of foam per 1 gallon of aqueous solution). Foam should be of a consistency that adheres to wood surfaces so that run-off is minimized. Since each foam machine can produce different foams, refer to the equipment manufacturer manuals and the foaming agent's label for specific instructions.
Pressure injection of Tim-bor
- Solution and foams can be injected into infested wood. Drill into the infested wood and inject until the liquid or foam runs out of openings, damaged areas, or kick-holes in the wood. This procedure is not an alternative to spraying, rather should be an addition to spraying when structural timbers are greater than 4 inches thick, and for selected wood destroying organisms.
- Tim-bor solution can also be injected into uninfested wood including wood adjacent to the infested areas. This procedure should also be used for painted or sealed wood. The sprayer or application equipment should be able to maintain 60-75 pounds of pressure. Only liquid solution will penetrate uninfested wood. Refer to the directions below for specifics on drilling and placement of drill holes.
- Injection holes (typically 7/64 or 1/8 inch in diameter) should be drilled in the area of suspected infestation. The holes should be drilled in a diamond pattern with the long axis along the grain, and the holes spaces every 12 to 16 inches. Holes should be spaced approximately 4 to 6 inches across the grain. (See Figure 1). When possible, the wood should be treated one diamond length pattern beyond the immediate area of visible infestation.
- Drill the holes through the widest dimension available. Drill approximately 3/4 the width of the beam. If the widest surface is not accessible, holes can be drilled in the narrower surface as in Figure 2. Drill holes approximately 8-10 inches apart.
- Press and hold the injection tip firmly into each hole and inject solution until runoff is observed from other holes, galleries, kick-holes, etc. When injecting solid wood, maintain the injection pressure for 15 to 60 seconds at each hole. Longer times give better penetration.
- Release the trigger, wait briefly and withdraw the injection tip. Excess solution can be absorbed with paper towels and collected for disposal (ordinary trash). Injection tips should be brass or other metal and fit snugly into the drilled hole to prevent dripping or spray back. Use a short injection tip (approximately 1 inch). This will allow the solution to flow into the drilled wood. If drilling overhead, be prepared for a solution to exit galleries; tarp or cover surfaces below.

Trouble Shooting / Hints
- Warm water will dissolve more readily.
- While 10% solutions are stable true solutions, the 15% solutions are super-saturated and may form precipitates, if allowed to stand or be stored overnight, or lose water via evaporation.
- You may use a hand paddle or mechanical mixer for mixing the Timbor solution.
- Over sided containers help prevent careless spills and minimize splashing during mixing.
- Always add the Timbor powder to water; adding water to dry powder is not recommended. This tends to form clumps of material that dissolve slowly.
Notes for Powderpost Beetles and Timbor Application
- Powderpost Beetles may have adults emerging from treated wood up to a year, due to their life cycles.
- If the wood is too dry (less than 15%), depth of penetration with the Timbor may only occur to the top 1/4 inch. To solve this, spray the wood first with water to increase moisture.

I have been using Tim-bor for several years and it has worked great. I like that it is clear and practically odorless. Makes it good for crawlspaces or areas that will be exposed. I also like ordering from DYI Pest Control. They are very responsive when I have questions, the items I order are shipped quickly and arrive undamaged. I will be ordering from them again and again.
- Great Product
We use and sell Timbor to our clients and have always had great results and feedback from our customers.
- really great bug killer
I have used this product several times to treat for wood fungus. Instant results on killing bugs, Snails dry up in days. Have not seen any signs wood fungus growth over the last 4 years.
- Excellent Product for Our Needs
This is a great, inexpensive product for using on our customers' boats. All of our customers have all loved it.
- Log Home Will LAST forever!
When my logs were completely bare, I saturated them with a solution of Timbor. After completely dry, Added Timbor again to "Timber-Pro" and applied to home. I have done this 3 times now and I feel my home is totally protected. I also pit a fine line around the top brick on the foundation of the house that any such bug would have the need to cross. I feel I now have little to nothing to worry about. I do in fact do a monthly walk around inspection and on occasion find a small dust pile and a hole. I take acetone in a syringe and fill the hole. Critter is now dead and hole abandoned.. Geezzzz, i love my Log Home! So easy to care for, so easy to cool and heat. Life is good!
- added protection
my use of product has added peace of mind to every job with its application... I will not complete a wood job where it has not added thus giving me assurance of total protection
- Non toxic pest control, easy to apply, that works!
I'm a syndicated radio journalist. I learned about Timbor while interviewing an entomologist that's been in charge of non toxic pest control on the University of California campus for many years.
I used it on an old house in the woods while doing repairs. We put the borate in water and brushed it on all the new wood. Before the application we were having swarms of termites each Fall.
- works great! Easy to use and stops the bugs quick.
I used it on some log beds I built and after one application I didn't see anymore little piles of dust forming around the base of the bed. The larva in the wood passed away quickly and my project was saved.
