BORACARE (Bora care) is a borate-based product that provides prevention and control of Termites, Carpenter Ants, Powderpost Beetles and Decay Fungi. Boracare can be used on all cellulosic materials including wood, plywood, particle board, paper, oriented strand board (OSB), cardboard, and wood composite structural components. If you are looking to kill and prevent mold, please see BORACARE with MOLD-CARE.  Also, a dye can be added to the Bora-Care solution when treating studs or wood inside wall voids called Turf Mark Blue

Active Ingredient: Disodium Octaborate Tetrahydrate (Borate) 40%
Target pests: Wood Destroying Fungus, Termite Control and wood-destroying insects such as termites, carpenter ants, powderpost beetles, etc.
Application: For powder post beetles, Boracare must be used on untreated wood. It is preferred over other treatments such as timbor in treating furniture because Boracare dries clear and will leave the furniture in its natural state. It will also absorb much further into the wood so you know the infestation is treated. Boracare is diluted with water at a 1:1 - 1:5 ratio depending on the pest you are targeting.
Yield: One gallon of Bora-Care will treat approximately 100 lineal feet of 2 x 4 stud wall. This includes sill plate and header. For other dimensional lumber, logs, or siding and plywood, please see the product label to the left. Typically, one gallon of concentrate Bora-Care will treat 800 square feet of a 2x4 stud wall, and 500 square feet of a crawl space or attic.
Coverage Area: Post construction and active infestations use rate is 1:1
Preventative use rate is 5:1
Manufactured By: Nisus (UPC: 616609111025)

How Bora Care Works

Boracare contains an inorganic borate salt, soluble in water, with insecticidal and fungicidal properties effective against wood destroying organisms. A patented carrier system allows Bora-Care’s active ingredient to diffuse into wood. This system makes Bora-Care more effective than products designed to treat only the wood’s surface. It is particularly suited for seasoned or kiln dried wood.

Bora-Care provides double protection by acting as both a toxicant via ingestion and a deterrent to termite tubing. This means that termites are kept out of structures, preventing wood damage. When termites or other wood-destroying insects ingest BoraCare, the borate active ingredient poisons the microorganisms in the insects’ digestive tracks that are needed to break down the cellulose in the wood. Essentially, it causes the insects to starve to death. Insects have shown no ability to develop resistance to borates.

Bora Care Target Pests

Wood destroying fungus, termites, carpenter ants, wood-destroying beetles such as powder post beetles

PESTS CONTROLLED WITH BORACARE: Subterranean Termites (Reticulitermes, Heterotermes), Formosan Termites (Coptotermes), Drywood Termites (Kalotermes, Incisitermes), Dampwood Termites (Zootermopsis, Neotermes), Powderpost Beetles (Lyctidae, Bostrichidae), Anobiid Beetles (Anobiidae), Old House Borers, Longhorn Beetles (Cerambycidae, Hylotrupes), Ambrosia Beetles (Platypodidae, Scolytidae), Carpenter Ants (Camponotus), Decay Fungi (Rot), Brown Rot (including dry rot), White Rot, Wood Decay, Algae

Target Uses of Bora Care

BORACARE provides prevention and control of Termites, Carpenter Ants, Powderpost Beetles and Decay Fungi. Boracare can be used on all cellulosic materials including wood, plywood, particle board, paper, oriented strand board (OSB), cardboard, and wood composite structural components. Since Boracare is applied directly to the wood, it can be used in areas where environmental contamination is of concern. The active ingredient in Boracare is an inorganic salt and once in place will not decompose or volatilize out of the wood. Treatment is long lasting as long as the treated material is not exposed to rain, continuous water or ground contact.

Boracare is most frequently used for pre-construction or post-construction preventative treatment of listed wood-infesting pests on structures. Boracare can also be used for remedial treatment of active infestations, such as in attics for treatment of drywood termites. Boracare can also be used to treat wooden items like interior trims or furniture, provided there is no stain, paint, or similar finish on the items. In addition to cellulosic materials, Boracare also can be used on concrete to prevent termite tubing.

ACTIVE INGREDIENT: Disodium Octaborate Tetrahydrate (Borate) 40%

Bora Care Application Instructions

Boracare can be sprayed, brushed or foamed onto bare wood surfaces and voids. The product cannot be fogged. Wood treated with BoraCare will appear darker than normal for a few days until the chemical dries in. Boracare will not affect the paint or staining of the wood. Wood treated with Boracare is non-toxic to humans and animals. Boracare must be diluted with hot water in a bucket and then added to your sprayer. Failure to pre-mix in a bucket will cause your sprayer to clog.

Mixing – The use of an impeller-type mixer that can be used with an electric drill aids the dilution process. Always mix in a separate container then add the solution to a spray tank. Use 1:1, 2:1, and 3:1 solutions within 24 hours after mixing. 5:1 solutions will remain stable for up to 30 days. Do not leave unused solution under pressure or in tank overnight.

*Always read the product label completely before use.


The yield of Boracare varies greatly depending on use and total volume of wood to be treated (not just surface area). Typically, one gallon of concentrate at a 1:1 ratio will treat 800 square feet of a 2x4 stud wall or 500 square feet of a crawl space or attic. On non-cellulosic materials, one gallon of finished solution treats 400 square feet of surface area.

For siding and paneling, one gallon of concentrate at a 1:1 ratio will treat 800 square feet of 1” wood by spraying only one side. If siding or paneling is ½” thick, the same amount of solution treats 1,600 square feet.

*See product label and supplements for charts and worksheets to aid in calculating the amount of Boracare needed for your application.

Standard Application Dilution rates / Mixing Ratios for Boracare:

*1:1 parts water to Boracare – 23% - active infestations, post-construction applications; application to wood more than 4 inches thick for wood-infesting beetles or Fungi or Algae

*2:1 parts water to Boracare – 16% - foaming or misting application for termites or carpenter ants; hardwood floors for some wood-infesting beetles

*3:1 parts water to Boracare – 13% - remedial control of Fungi and Algae on wood less than 4 inches thick

*5:1 parts water to Boracare – 9% - most preventative or pre-construction treatments

See Remedial Injection Bulletin for an easy flow chart of ratios for existing construction treatments.

Bora Care is for use in the following areas:

Homes, Apartments, Garages, Museums, Public and Private Institutions, Schools, Hotels, Hospitals, Kennels, Stables, Farm Buildings, Trucks, Trailers, Warehouses, Non-Food Areas of Supermarkets, Restaurants and Food Processing Plants

Surfaces: All non-food contact surface cellulosic materials including wood, plywood, particle board, paper, oriented strand board (OSB), cardboard (non-food packaging material), wood composite structural components, concrete, block, brick, metals, PVC plumbing pipes and other non-cellulosic materials found in structures.


Use Bora-Care on new construction. For termite pretreatments, simply spray a two-foot tall continuous barrier directly to the wood using a tank sprayer or portable backpack sprayer. This includes the walls, piers, interior slab or basement walls, plumbing penetrations, pipe chases, bath traps, and any other foundation penetrations. Treating this way insures that all termite entry-points are treated. You can also use Bora-Care as a whole-house treatment for general pest protection to prevent infestations of decay fungi and wood destroying pests such as drywood termites and destroying beetles.

Remedial Wood Structure Treatment – Spray and/or inject Boracare solution into beetle holes, termite and carpenter ant galleries and decay pockets. Apply 1 coat of solution to the point of surface saturation to all infested and susceptible wood, paying particular attention to infested areas. Apply 2 coats to those wood members with only one or two exposed sides. Wait at least 20 minutes between applications.

Wood Flooring (Remedial Treatment) – Treat by spray, brush or roller application. Prior to application, remove any existing finish by complete coarse sanding or stripping. Use a 2:1 (water to Boracare) solution at a rate of approximately one gallon of solution per 500 square feet of floor surface. Two coats may be required for termite infestations, waiting at least 1 hour between applications. Moisture content must be 10% or less before applying final finish.

*Boracare may be applied by misting or foaming at high expansion rates into inaccessible wall voids, wall studs, and wood members. (Boracare cannot be used in fogging machines.) See product label for complete details.

Preventative treatment – For framed wood surfaces above ground, apply a 1:1 solution. Treat remainder of structural wood in a 5:1 solution. Concentrate application in areas susceptible to attack, to include all sills, plates, floor joists, piers, girders and subfloors. Treat all exterior wood including siding, facias, soffits, eaves, roofing, porches, decks and railing. If Bora-Care is the sole preventative treatment for subterranean termites, a 1:1 solution must be used.

Buildings on crawl spaces and basements (preventative and pretreatment) – Use a 1:1 solution and apply in a 2 foot uninterrupted band to all structural wood surfaces in crawl spaces and basements. To prevent termite shelter tubes on crawlspace walls, apply to concrete or block walls in a 2 foot band up from the ground on interior wall surfaces. Apply at the rate of one gallon to 400 square feet of surface area.

Please read the label for more instructions.


*Do not use to directly treat soil.

All exterior wood - DO NOT APPLY IN RAIN OR SNOW. Do not expose treated exterior wood surfaces to rain or snow for at least 48 hours after treatment. For longer performance, exterior wood surfaces will require a topcoating with a water-resistant finish such as paint or exterior stain. Apply within 6 weeks of treatment. Boracare must dry completely (at least 48 hours) before applying any protective topcoat.

Treatment of exterior wood surfaces less than 2 inches thick, such as decks, sheds and fences – Apply only to bare wood or to wood surfaces where an intact water repellent or finish is not present. Remove paint or finish prior to application. Apply one coat of solution to all wood surfaces. Apply two coats to heavily infested areas and to those surfaces where access is limited to 1 or 2 sides of wood members.

Exterior wood thicker than 2 inches, Logs, timbers, beams, etc. – Use a 1:1 Boracare solution to all surfaces. Treat bare wood only. Refer to application charts for specific sizes of logs or beams. Typically, 2 coats are required to treat round logs 10” or greater in diameter and rectangular logs larger than 6” x 12”. Wait at least 1 hour between applications.

When treating around the exterior of structures, cover and protect shrubbery and plants that may be potentially exposed to Boracare, since it may be phytotoxic to plants.

Bora Care Features

*Pretreatments can be done IN ONE TRIP.  No need to worry about weather delays or pumping chemicals into the soil, crews can remain on the job site during treatment, and treatment will last for many years.

*Absorbs all the way into wood for the most complete borate treatment available.

*Dries clear, doesn’t affect future painting or staining of wood surfaces.

*Emits no VOCs (volatile organic compounds).

*Qualifies builders for LEED for Homes points as well as points in many other green building programs.

*Boracare is the only borate-based termiticide that is EPA-registered as a primary perimeter termite pretreatment for new construction with its own product-specific field efficacy studies.

*Bora-Care remains for the life of the treated wood, so no retreatments are necessary (provided wood is not exposed to rain, continuous water, or in contact with the ground).

Extra Tips for Using Bora Care

*Always pre-mix in a separate container before filling spray equipment.

*Use only on raw wood materials. Boracare will not penetrate paint, stain, or sealants.

*Older wood boring beetle larvae and especially pupae already present in the wood at the time of treatment may occasionally emerge sometime after treatment.

*If finished surface appearance is a concern, a wood cleaner such as Mold-Clean may be used prior to Boracare treatment.

*The rate at which Bora-Care is absorbed varies depending on the thickness of the wood and, particularly, the moisture content of the treated wood. Higher moisture content will allow for more rapid absorption.

* An appropriate dye or colorant such as Turf Mark Blue may be added to the solution when diluting Bora-Care with water to make it easier to see where Bora-Care has been applied.

    By Doris on April 27, 2010
    Verified Purchase

    I had my home sprayed with this for the wood post beetles and they were gone...until today they came back. For over a week not a single one was sighted. This does work on contact but the reason that I bought this product was because it claimed to kill up to twelve months...I didn't even get twelve days of peace.

    5 of 5 Stars  Bora-Care is the BEST!
    By Michael on January 11, 2010

    I had a termite control company give me an estimate to spot treat my drywood termites and it was astronomical! I found that had the same product Boracare for a fraction of the cost. I treated my infestation using the recommendations on the website and now I have a termite free home and more money in my pocket!

    5 of 5 Stars  Easy to mix and use, and I don't get sick
    By Larry on June 8, 2010
    Verified Purchase

    I have used half a gallon for remediation of dry wood termites on fascia boards by using 1:1 and 1:2 dilutions applied to bare wood and by injecting in drilled holes where the wood is covered by paint. I like this product as well as the Bifen IT, as they are fairly non-toxic to people and animals. I can use both of them extensively without feeling ill effects myself. I added Bifen IT to the Boracare solution to get a 0.12% Bifen IT concentration (double strength). The Bifen IT works as an quick termiticide and the Boracare provides long term protection. Now that I have stopped the active infestations, I can take my time and protect the rest of my house's fascia, rafter and joist board ends with simply painting a 1:5 Boracare dilution on the ends of the boards (where dry wood termites enter). I will need a 2nd gallon of Boracare to protect the entire house and will be ordering soon. For approximately $200 of products from Domyownpestcontrol, I will have done the remediation work and the whole house protection. This has been a lot of work, but I have saved many thousands of dollars, plus I can take my time and know that the job is done right.

    5 of 5 Stars  Bora-Care Product Review
    By Patrick on April 29, 2010
    Verified Purchase

    I don't know why the wood adjacent to my bath tub wet wall was moist?  There were no leaks and the plumbing vent to the roof was well sealed.  Condensation?  The bath drainpipe and water inlets come up through a hole in the slab. The subterranean termite varmints tunneled 10' or 40' under the house slab and surfaced at this point of exposed earth attracted by the moist wood. They swarmed the first warm days in Spring. I treated the exposed earth area with the Dominion 2L termiticide and then filled it with sand. I treated the slab, wood framing, floor and molding with a 2:1 mixture of BoraCare. I sprayed BoraCare down from the attic and drilled holes in the walls where there was no other access. I will finish by treating the ground around the house with Dominion 2L. My problem appears to be solved for under $200. Thanks!

    Used product on wall studs, when I was repairing a wall due to termite damage. My project lasted about three days. I used a 1:1 mix and I did not pay too much attention to the one day usage. The product crystalized in my sprayer - took awhile to clean the sprayer.

    5 of 5 Stars  Boracare seems to have worked
    By Bryan on December 1, 2014

    There were tiny holes in my ceiling sheetrock and little termite pellets falling and accumulating on the floor every day. I really didn't want to tent the house so I decided to research and try Boracare. After crawling around in my attic and trying to spray most of the wood, and especially the areas where I could see termite damage, the pellets have stopped falling. I was especially interested in this product because I read that the termites can't detect it and take it back to their friends, killing the whole lot somehow. So this makes me think/hope that even though I wasn't able to spray it everywhere, it will somehow end up getting them all.

    By Linda on November 25, 2014

    I can only comment on the application of this product since I just applied it. The stuff is like pure cornsyrup in consistency but actually is quite easy to use - definitley use HOT water to mix and use a painters aggitator and drill. Once mixed it is easily sprayed on the house but stays very sticky. Stain is easily applied over this once dry. Easy to clean up with water but stays sticky on wahtever is gets on.

    I use it on trim and flooring, and all wood going into my shop for furniture projects, applying it with a garden sprayer to the backs of the material that is set up on multiple sawhorses. I always use it, having seen a powder post beetle infestation that ruined an antique Italian furniture collection.

    By Karen on October 21, 2014

    Material came in a timely manner. Read online reviews and took folk's suggestions to mix with very hot water...seemed to do the trick as the material mixed well with the warm water and we had no trouble spraying. It's an expensive product and we used a lot more than we thought we would need. As far as "how did the product do?".... It will take a year or so to see if we have more powder post beetle problems, so my rating will be a conservative 3.

    When the little termite guys decided to move into my construction site my husband and I wanted to find a DIY but safe method of evicting them. We purchased Boracare and within a day of spraying all of the trails went dead. No deadly to human chemicals needed, so needless to say we were very happy with the product! To add to that the customer service from DMyOPC is exemplary! Cheers and Thank You!

    I have an on going problem with powder post beetles and have used the product in the past. Shipping may not be Fast but I get my orders fairly quickly. Suggestions: Follow the directions and mix with a paint mixer it is the easiest and best way to get it in suspension. My old hand sprayer puked and I had to run into town and buy a replacement. I bought a cheap sprayer, don't, spend the money on a good one. The quality of your hand sprayer will play a big part on how well you cover the surface. I would up wasting to much with a cheap one.

March 2, 2010 E. asked:

QWhat is the difference between Bora-Care and Timbor that makes the price of Bora-Care cost so much more?
They both seem to control the same pests. Container size appears the same. Is Bora-Care more highly concentrated therefore dilutes to cover more? I am confused. Can these be applied by a novice? What protection must one take?


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 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.  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. 

Just to recap if you have an existing infestation, you should use Bora-Care.  If you are just treating wood to be used in new construction or surface fungus, then Timbor is fine to use.  Both products are very safe, virtually odorless and do not require respirators unless you are in a enclosed space with no ventilation.  You should always wear gloves and protect your eyes anytime you apply pesticides or herbicides.  All you need to apply either product is a one or two gallon hand pump sprayer.  Timbor is used at 1.5 lbs of Timbor to each gallon of water.  Bora-Care is mixed 1:1, one gallon of Bora-Care to one gallon of water which will make two finished gallons. Both products should be mixed in a 5 gallon bucket and then poured in your sprayer to use.  We sell these products to homeowners every day and they are very successful treating their issues and you can have great success too.  Remember that we are always here to help.  Good Luck!

February 12, 2011 Michael asked:

QTermidor vs. Bora-Care - Which one should I use for dry wood termites?
I have dry wood termites in my home, and I am wondering if i should use Termidor or Bora-Care?


Since you have droppings then that means dry wood termites is your issue and you probably live in CA or FL.  If you see droppings then there are "kick out"holes which you should be able to find on the wood where the termites that are inside the wood are kicking out their pellets onto the floor.  This will help you zero in on the wood that you are treating. 

Both Termidor SC (fipronil for termites) and Bora-Care will work, but Bora-Care is typically the better one to use for this situation. Termidor SC is not a wood treatment product, so for it to work you have to drill holes EXACTLY where the termites are and it has to touch the termites to work.  If you miss where they are, it will not work.  Also, Termidor SC does not really have any residual in the wood, so after you treat inside the wood with Termidor SC and it dries, that wood is exposed for future termite and beetle infestations.


Bora-Care is usually the preferred choice if most of the wood is exposed and it is raw wood you are treating, meaning it is not painted, stained, or sealed, it is just normal wood.  Bora-Care is made only for wood, and you do not have to know exactly where the termites are for it to work which is a plus.  Bora-Care is sprayed evenly over all exposed surfaces of the wood and actually penetrates through the entire piece of wood.  When the termites in the wood try to consume the wood after it has been treated, they ingest the Bora-Care with the wood and die.  No matter where they are in the wood the Bora-Care will find them as long as you treated the exposed wood that you can see.  The other main benefit is that Bora-Care stays in the wood forever, so you will not have to worry about termites or beetles infesting the wood that you treated ever again.

December 2, 2009 Joe asked:

QMy house is approx. 2000 sq ft of crawl space. How much Bora-Care would I need for the job?

AHow much Bora-Care you need depends more on the size of the wood you are treating than just square footage.  Also, it's the lineal footage of the wood more than square footage.  Here is a link to a worksheet that you can fill out and it should give you the correct amount needed based on the size of wood you have and how much you need to treat.  Typically, each gallon of Bora-Care, after mixed 1:1 with water, will treat about 1000 square feet of space, but if you have larger sized wood (for example:  2 x 8 instead of 2 x 4), then one gallon of Bora-Care may only treat 800 square feet.  The worksheet should be able to get you an exact estimate.

June 10, 2011 William asked:

QCan Bora-Care be used on "pressure-treated" wood if it is not painted, or stained?

ANo, Bora-Care will not work on pressure treated wood either.  Pressure treated wood is made to not let moisture into it, and since Bora-Care depends on moisture to allow it to penetrate through the wood it will not work on pressure treated wood.  Bora-Care will only work on raw wood.  Wood that is not painted, stained, sealed, or pressure treated.  Also, pressure treated wood prevents against all of the things that Bora-Care does anyways, so it does not need to be treated.

November 10, 2014 Rick from Niceville, Fl asked:

QDo you have inserts to be placed in walls for repeat injections of termiticides?
I am trying to decide how I will treat the header of our house for Formosan termite attacks. We have what one contractor called a conducive condition in that he believes that the insulation wrapping our house is not a sufficient moisture barrier. This was the excuse used by Terminix to not fully cover damage. Lord willing, I will inject each wall void with BoraCare as a foam, which brings up another question: How do I calculate the required volume of BoaraCare foam to fill the voids? In other words, how much expansion should I anticipate per say gallon of 1:1 mix of BoraCare with ProFoam? I will be using a Chapin 1 gallon foamer - all supplies have been purchased from you all already. Another question: I read somewhere where one can place inserts in wood that can the used to inject termiticides, BoraCare (NOT as a foam, but as aqueous mix). I did not find them on your site. Maybe they are not necessary, but I wonder if they would make it neater for application. I realize that this drilling in to header from inside the house (brick outside beyond the wood framing), but this place (Bluewater Bay, in Niceville, FL) is horrible- ~$21,000 damage last year, maybe the same this year. We have had a new roof put a couple of weeks ago. I purchased a Termatrac T3i and have used that successfully to find an infestation that I have some professionals treating (not Terminix, of course- we learned about them the hard way).

A I'm going to try and answer this as simply as possible but if any of it doesnt make sense please call in as it may be easier to explain over the phone. If you use boracare, in either its liquid or foam form and appy it to raw natural wood, it will absorb into the wood, become one with the wood, and last for the life of the wood. This means one proper application of Boracare will eliminate any termites currently in the wood and protect it from any future termite infestations for the life of the wood. Basicaly if a colony comes along in the future and tries to start taking up residence in a piece you have thoroughly treated with Boracare, it will die once it starts consuming the wood and ingesting the Boracare. Active infesatation rate is 1:1, preventative is 5:1. If you choose to foam you would want to use about 4 ounces of the Pro Foam concentrate to each gallon of mixture in the Chapin foamer of Boracare and water. That is a good rate for an even expansion. That being said, you should not be trying to fill the entire void. No exterminator would do that or even consider doing that even if you wanted to pay them to. The proper way to do it is to drill holes on either side of any stud, frame, or header and allow the foam to run down the sides of the wood and absorb in and expand as close to the wood as possible. You want it to aborb into the wood, not the insulation. Also, I am not aware of any inserts like what you mentioned on the market.

November 9, 2014 Terri from Cardiff, Ca asked:

QHow can I tell if Boracare is being absorbed as needed versus evaporating?
I want to treat my 50 year old tongue and groove ceiling which has some termites. The wood has a transparent stain on it that doesn't seem water repellant. How can I tell if the Boracare is being absorbed adequately? Stripping the entire ceiling or drilling holes throughout would be an enormous job so I would like to try Boracare on a small area and see whether it is going to work before deciding what to do with the rest.

A If there is any type of stain on the wood you are treating, Boracare will not absorb properly. The wood will need to be sanded down in order to treat the wood. You do not need to drill holes into the wood in order to apply Boracare. You can either paint it on or use a sprayer. For what you are doing, painting Boracare on the wood would likely be the easiest. Once it is dry, you can apply a second coat for added protection. Once that has dried, the wood can be stained again.

QHow do I exterminate powder post beetles?
I am remodeling a bathroom, and I found powder post beetle residue behind shower stall.

A For powder post beetles, we would recommend using Boracare. The wood you are applying this product to must be untreated, meaning no sealants. You will use 1 gallon of Boracare with 1 gallon of hot water. You can either spray the wood or paint it on. Once the product is dry, you can apply any type of sealants to the wood.

QCan water based sealers be mixed with Boracare?

A No, Boracare has to be used first. A sealant can be used after the Boracare has dried.

QHow much wood to treat for Powderpost Beetles?
Found two joist where they exit and saw dust I sprayed the area near (borecare) , only 1/2 the basement and entire beam where I saw holes. and the flooring above. Do I need to do entire basement, i.e. sill plates etc or just do near the area where damage occurred?

A Applying Boracare where you had the damage should be sufficient. While Boracare does aborb completely through the wood, it will not spread throughout to untreated parts of the wood. If there are already eggs in the wood that is not treated, you will have to reapply the Boracare if and when you notice activity or damage.

QWhat is the recommended temperature to apply Bora Care?

A BORACARE can be applied in any temperature as long as it is not below freezing. However, the warmer the temperature the easier it will be to mix and apply the BORACARE because of its thick consistency.

QCan I use Bora-Care to control and stop Carpenter bees on new wood under my house before they start coming?

A Bora-Care is not labeled for Carpenter Bee Control as it must be ingested to affect the insect. Carpenter bees only tear away at the wood, they dont eat it like termites do so they normally will not be affected. Carpenter bees are normally less attracted to treated wood but even after sealing the wood, you could use a residual spray like Cyonara 9.7 to spray across the wood to kill them just from landing on the treated surface.  Cyonara is also found in one of Carpenter Bee Kits here.

Qwill Boracare penetrate t1-11 or plywood considering these construction materials are laminates?

A Boracare is only able to penetrate into raw, untreated, unstained or painted wood therefore it would not penetrate into plywood with laminate on it.

QHow many years will the deck applied Boracare last each of with and without paint?
I bought your Boracare 4 gallons last week and will receive Wednesday to apply to my renew deck. I want to know that how many years my deck will last each of both condition of deck with paint and without paint after applied Boracare? My concern is I have to remove paint if I want re-apply Boracare to my deck again in the future.

A Boracare lasts for the life of the wood if it is not exposed to rain, continuous water or ground contact. The amount of time Boracare lasts in the wood will depend upon those factors. There is no specific guarentee because some conditions are more or less favorable than others. In your case, we would recommend using a sealent of some kind after the application of Boracare. Do not expose treated exterior wood surfaces to rain or snow for at least 48 hours after treatment. For longer performance, exterior wood surfaces will require a topcoating with a water-resistant finish such as paint or exterior stain. Apply within 6 weeks of treatment. Boracare must dry completely (at least 48 hours) before applying any protective topcoat. If there is a current infestation, you will do a 1:1 application of Boracare. If this is just for preventative measure, you will do 5:1 application. Make sure the water is very hot when you are spraying it.

QHow many years will I need to reapply Boracare if I don't do surface finish after treated deck?
I applied boracare on my old deck without surface finish about 4 years ago. I want to know how many years I will do it again.

A Without treating the surface with a sealant, paint or stain after applying Boracare, the product will evaporate out the surface within a couple months. We would recommend doing a complete reapplication of your decking with Boracare and followed by a surface finish. It is important to seal your treatment of Boracare within 1 month with a sealant, paint, or stain to ensure the Boracare is locked into the wood. You will need to reapply the sealant or paint per the product label you choose.
