“We’ve got a mot daeng fai problem here at the moment. And not only do they generally make the place look untidy, but they are out to inflict maximum pain. Only small things, but they must walk around perpetually fucked off with the world to want to hurt people like that.”

Borax or Boric acid powder?
I know Borax for cleaning, but Boric acid powder for insecticide
Have you tried a pharmacy, they should have it in Pharma grade which will cost more
But here I use a garden sprayer and Chaindrite, which is cheap, or better is Shelldrite, but harder to find and not as nice to use as overspray gets on your skin and stings like a bitch.
That insect chalk stuff is borax, you mark the boundaries with the chalk where you don’t want the insects to go.
Can be bought in all supermarkets
They sell it in chemical shops, by the 25kg, but there was a nearby shop that split it up and sold by the kilo

I have mixed with jam and hope to get rid of the millions of tiny red ants plagueing us this year
Boric acid is also used as welding flux and should be available where they sell welding supplies.
Borax or boric acid is good for Bamboo treating as well, to remove the BokBok as they call it in the Phils…
Drill the bamboo poles, pour it in, block the 2 exit, leave it some time and Bamboo shall be safe.
Bought my last lot of Boracic acid in China Town Penang on Love Street ..little Chinese English speakin guy had enough chemicals to blow up the peninsular….
As an addition I have found that Northern Chemicals in Chiang Mai offer Borax at 870Bt /25kg and Boric Acid at 1500Bt /25kg
Ask in your local wet market, it’s used as an illegal preservative on meat. Other than that you can only get it from a chemical supply store, it’s not available in normal shops. Try this place, https://www.chemipan.com
Borax can be bought at World Chemical in CM, on the road from SuperHighway 11 -intersection to San Kampen – connecting to the airport, right hand side.
I used this supplier to get borax powder. A bit more expensive maybe but buying online was painless and received the stuff within days. Cleared out the ant problem.

Good Karma Online Health Food Store

They are based in Phuket.

I dont know about Thailand, but certianly here, in Indonesia, the sale of Borax is tightly regulated, because it was added to food by meatball food vendors, to make the food look better. (not particularly healthy for you though)
Here as well, it was added to noodles, rice, meat products!
Borax used to be found especially on pork meat to make it look “redder” or more fresh in the markets. Hopefully you’ll find it elsewhere.

I had this problem about three years ago and devoted a weekend to ridding myself of them. Teepol was the stuff that worked. I showed no mercy, if there was so much as one ant left I doused it.

Ant Baits: A Least Toxic Control

by Barb Ogg, PhD, Extension Educator


When faced with an insect pest problem inside the home, too many people reach for an aerosol container. For many ant species, baits are the best management tactic because the entire colony is destroyed. This results in a more permanent solution to their ant problem. In addition, many baits have low toxicity to people and pets.


The trick to using baits is to make sure that the offending ants find the bait, eat it voraciously and take it back to the nest to the queen. If residual insecticide sprays are used, the foraging ants may die before they feed or take the bait back to the next, counteracting the effectiveness of the bait. Do not use insecticide sprays if you want to bait for ant control. If the bait is attractive to the ants, the entire colony will be destroyed within a few weeks. No insecticide sprays will be necessary!




Not all ant species can be controlled by baits and some baits work better than others. In general, ants that eat a wide variety of foods will be less affected by baits because the bait will comprise a smaller proportion of their food. Sugar-loving ants are the easiest to control.


Sweet-Loving Ants. The easiest ants to control are sweet-loving ants. You can use jelly to increase the ant foraging behavior and make the toxic bait more effective. Apply a ribbon of jelly (1-1/2″ x 1/4″) to masking tape in the areas where you have seen the offending ants, especially around water sources and window ledge. Masking tape works great because it stays in place and is easy to remove and discard later. Experts say that mint or mint apple jelly seems to be the most attractive to foraging sugar ants. A plastic squeeze bottle with a pointed tip makes a convenient applicator.


Sweet-loving ants should begin feeding on the jelly within a couple hours after bait placement. These “survey stations” can be used to pinpoint areas that should be baited. Experts say to use one survey station for each 50 square feet of living space and each 15-20 feet around the house. This can mean lots of jelly and masking tape; however, later you wil be able to use the toxic bait more efficiently and save time and money in the long run.


About two hours after setting out the jelly stations, you should count the number of ants foraging at each station. If there are more than 10 ants feeding at the station, the toxic bait should be placed at the active site. If there is tape with no feeding ants, the masking tape with jelly ribbon is discarded. The most successful baits are those that contain a slow-acting stomach poison so the foraging ant workers will take the bait back to the queen. We recommend baits with boric acid or hydramethylnon as their active ingredient.


Grease and Protein-Loving Ants. Big-headed ants, little black ants and pavement ants prefer grease and protein; in addition, they will also feed on fruit juices. They respond best to protein/grease baits.


A protein/grease bait recipe from Field Guide for the Management of Structure Infesting Ants is:


2 ounces (4 tablespoons) peanut butter

3 ounces (6 tablespoons)


3/4 teaspoon boric acid

There are some commercially available baits (DRAX®-FP) that will also work for grease-loving ants.


Carpenter Ants. Carpenter ants will eat sweets; they also eat a wide variety of other food. Some baits are registered for carpenter ant control; however, they do not work as well as on other ant species.


A baiting technique can be used to locate carpenter ants’ nests. Purchase some live crickets at your local pet store. Kill a couple and place them in an area where carpenter ants forage. Within a short time, the workers should located the crickets and drag them back to the nest. By tracking their movements, it may be easier to find the nest location. Because carpenter ants forage during late afternoon and evening hours, make sure bait is available at this time of the day.


Ant Species Controlled by Baits:


Argentine ants (sweet bait)

Big-headed ants (sweet and grease bait)

Little black ants (sweet and grease baits)

Pavement ants (sweet and grease baits)

Pharaoh ants (use hydramethylnon bait)

Odorous house ants (sweet bait)

Small honey ants (sweet bait)

The following baits are registered for ant control:


Terro® (OTC) | gel | boric acid/sugars

Pic® liquid (OTC) | gel | boric acid/sugars

Drax® Ant Kil Gel (PRO) | gel | boric acid/sugars/apple/mint (sugar-feeding ants)

Drax®-FP (PRO) | gel | boric acid with peanut butter/oil (protein and grease-feeding ants)

MAXFORCE | gel, granules | hydramethylnon

No structural pest causes more confusion than termites. Most homeowners have little knowledge of these troublesome insects, and what it takes to get rid of them. Our understanding of termites has progressed considerably in recent years.

New management tools have emerged, and a significant number of pest control firms are now using baits as an alternative form of treatment. This publication will help homeowners understand termite baits so that they can make a more informed purchasing decision.


Subterranean termites, the variety common to Kentucky and most other states, live below ground in cooperative, intermingling groups known as colonies. Mature termite colonies tend to be decentralized entities occupying multiple nesting and feeding sites, interconnected by underground tunnels. The dimensions of a colony can be quite variable. Larger colonies can have hundreds of thousands to millions of individuals, occupying areas of up to half an acre. Smaller colonies may contain less than 10,000 individuals, with a foraging “footprint” no bigger than a bedroom. In some cases, larger but fewer colonies may be present; in others, individual colonies may be smaller and more numerous. In residential areas, the colony or colonies responsible for damage may actually be located in a neighbor’s yard, rather than beneath the house that is infested.

Subterranean termites excavate narrow, meandering tunnels through soil, eventually encountering wood, their primary food. Decaying tree roots, logs, stumps, woodpiles, and plant debris afford a ready and abundant supply of food for the colony. In nature, termites are very beneficial since they aid in the decomposition of organic matter and the return of nutrients to the soil. Occasionally during their persistent foraging, termites encounter wood within buildings. Once a suitable feeding site is found, the workers establish an invisible odor trail to attract other termites to the structure.

Subterranean termite infestations can go undetected for years, hidden behind walls, floor coverings, and other obstructions. Over time, significant damage can result. The cryptic nature and tenacious foraging habits of these insects also pose a challenge to control efforts. Unlike other services such as plumbing or electrical work, termite control involves living creatures. Traditional treatments may fail at times, underscoring the need for other forms of management.


For years, the standard method of controlling subterranean termites was to apply a liquid pesticide, known as a termiticide, to the soil. The goal was to create a continuous chemical barrier around and under the building in order to block all potential routes of termite entry. Termites attempting to penetrate the treated soil were either killed or repelled. In actual practice, there are many obstacles to achieving such a barrier. Many potential termite entry points are hidden behind walls, floor coverings, and other obstructions. Even where access for treatment is possible, it is hard to uniformly wet soil and achieve thorough coverage. A typical “barrier” treatment may involve hundreds of gallons of pesticide injected into the ground alongside the foundation, beneath concrete slabs, and within foundation walls. Homeowners sometimes object to the drilling and disruption that such treatments often require.


Termite baiting employs a very different approach. With baits, small amounts of material are deployed like edible “smart missiles” to knock out populations of termites foraging in and around the structure. Foraging termites consume the bait and share it with their nestmates, resulting in a gradual decline in termite numbers. Some baits may even eradicate entire termite colonies. A comprehensive baiting program then seeks to maintain a termite-free condition on the customer’s property through ongoing inspection, monitoring and re-baiting as needed.

can destroy large numbers of termites foraging in the vicinity of a structure.

The baits consist of paper, cardboard, or other palatable food, combined with a slow-acting substance lethal to termites. The bait must be “tasty” enough that termites will readily consume it, even in the presence of competing tree roots, stumps, woodpiles and structural wood. If the bait kills too quickly, sick or dead termites may accumulate in the vicinity of the bait stations, increasing the chance of avoidance by other termites in the area. Delayed-action also enhances transmission of the lethal agent to other termites, including those that never fed on the bait. Entire colonies can be eliminated in this manner, although total colony elimination is not always necessary to afford structural protection.


Various methods of termite baiting are employed by pest control firms. Some baits are inserted below ground out in the yard, while others are installed inside the building in the vicinity of active termite mud tubes. On some properties, baits may constitute the only form of treatment; on others, they may be supplemented with a partial or complete liquid application.

Installation Below Ground

Most termite bait components (paper, cardboard, etc.) decompose rapidly under ground. Consequently, most installations initially utilize untreated wood in the stations. Once termites are detected in the wooden monitors, the bait material is added. Termites cannot see or smell the baits underground; they more or less wander into them during their persistent foraging activities. To increase the odds of discovery, the stations are installed at fixed intervals (typically 10 to 20 feet apart) around the entire outside perimeter of the building and in known or suspected areas of termite activity (e.g., around woodpiles, stumps, moist areas, and adjacent to previous termite damage). With patience and a little luck, the termites eventually find and feed on one or more of the bait installations.

One of the biggest challenges in baiting is getting termites to find the baits in the first place. The timetable for discovery will vary from property to property, depending on such factors as termite foraging intensity, time of year, moisture, and food availability. For example, on one infested property in Kentucky, more than a dozen monitoring devices were “hit” (attacked) by termites within two weeks of installation; on another home in the same neighborhood, no below-ground stations were attacked during a full year of intensive monitoring despite two concurrent termite swarms inside the home. Similar variances in bait detection by termites have been reported elsewhere in the country.

Because subterranean termites feed at multiple locations within their foraging area, chances are good that one or more bait stations will eventually be found and fed upon. In temperate climates such as in Kentucky, bait discovery usually will be greatest from spring through fall when termites are most active. Baiting during late-fall and winter is generally less fruitful. Termites may be found in below ground stations at sub-freezing temperatures, but their feeding activity and effects of the bait are greatly reduced. At times of the year when the ground is frozen, snow covered , or saturated, inspection of bait stations can often be curtailed until conditions once again become favorable for termite foraging and feeding.

The more bait stations installed, the better the chances of locating termites. Installing more stations increases the odds of encountering multiple colonies, or weakly associated “satellite nests” of the same colony — any of which could be of potential risk to the structure. Planning, patience and persistence are requisites for successfully using below-ground termite baits. Regardless of which product is used, the homeowner must be prepared and willing to accept the possibility of a lengthy baiting process.

Above-Ground Installation

Baits can also be installed above ground, in known areas of termite activity. Typically, the stations are installed directly in the path of active termite tunnels after the mud tubes have been broken. Other times, they can be mounted directly over termite-infested wood, drywall, or other surfaces. Effects tend to be more rapid with above-ground baiting, since the procedure does not require waiting for termites to find the below-ground installations. They are normally used in conjunction with below ground baiting, rather than as a stand alone.


Discussed below are various professionally-installed termite bait systems, and another one marketed directly to homeowners.


This product/system has been the most extensively tested of those currently on the market. Consequently, it will be discussed in some detail. The Sentricon Termite Colony Elimination System was developed by Dow AgroSciences (Indianapolis, IN), and is sold only through authorized pest control firms. The bait contains a slow-acting ingredient which disrupts the normal growth process in termites (i.e., termites die while attempting to molt). Termite control with the Sentricon System ® entails a 3-step process: (1) initial monitoring to pinpoint termite activity, (2) delivery of the bait, and (3) subsequent monitoring to provide ongoing protection of the structure.

Step 1. Monitoring- Termites are detected by installing plastic monitoring stations around the perimeter of the building.

Sentricon Station Housing

Setting the Sentricon station in the ground

The station housing (pictured above) is a hollow green plastic cylinder, about 10 inches long by 2 inches wide, with slits along the sides for termites to enter. Initially, each station is provisioned with two untreated pieces of wood, intended as monitoring devices for the presence of termites in the area.

The station is inserted into an augured hole in the ground, with the cover flush with the soil surface. Monitoring stations are installed around the outside perimeter of the building, at about 10- to 20- foot intervals alongside the foundation. Narrower intervals, while more effort to install and inspect, increase the odds that termites will encounter them during foraging. Stations are typically installed about 12 to 18 inches from the foundation, to avoid soil that may have been treated earlier with a liquid termiticide. Patios, driveways, and other paved surfaces are not a problem unless soil access is prevented around the majority of the structure. Oftentimes, stations can be installed farther out from the foundation, in adjoining planter boxes, etc. When necessary, stations can also be installed under pavement.

As a supplement to installations along the foundation, additional stations are installed in suspected termite foraging areas, such as near pre-existing termite damage, stumps, woodpiles, or moist areas on the property. Periodically thereafter (monthly, bimonthly, etc.) the wood monitoring devices within each Sentricon station are inspected for termite presence.

Step 2. Bait Delivery- When termites are found in a monitoring station, the untreated wood is replaced with a perforated plastic tube containing bait laced with a slow-acting termite growth inhibitor (noviflumuron).

To hasten the overall process, termites feeding on the wood pieces are carefully dislodged and placed within the Baitube. Eventually, these termites tunnel through and out of the perforated tube, reuniting with their nestmates in the soil. In doing so, they leave behind a colony-specifict scent that promotes recruitment of other nestmates to the bait. In order to promote additional “hits” (attacks) on stations, additional stations containing wood are installed near those receiving Baitubes.

Inspection of all Sentricon stations, with and without substituted bait tubes, continues until no more live termites are discovered. Empty, moldy or degraded baits are replaced and additional stations added as deemed necessary.

Step 3. Continued Monitoring-
After termites are no longer found in installed Baitubes, the baits are once again replaced with untreated wood pieces and monitoring continues. Even if the termite colony threatening the structure has been eliminated, termites from neighboring colonies can reinvade the area. Reinfestation can also occur if only part of the original colony or colonies was eliminated. Consequently, structures protected with Sentricon (and all other bait products and systems) will need to be continually inspected, monitored and maintained to guard against reinvasion from new colonies or previously suppressed ones. Once the termite population has been eliminated, the pest control firm will continue to monitor at three- to four-month intervals for an indefinite period.

Independent research studies, including some performed in Kentucky, indicate that the Sentricon® Colony Elimination System is an effective termite control option. Some of these studies involved structural that could not be controlled using conventional liquid methods. Despite Sentricon’s demonstrated effectiveness, diligence and persistence are requisites for success — as is true for any termite management program. In order to use Sentricon, companies must receive training and adhere to rigid quality assurance standards required by the manufacturer. Various enhancements have been added in recent years to facilitate performance and serviceability. Aboveground stations are available to hasten delivery of bait to termites evident within in the structure. Another enhancement, “ESP Technology,” utilizes a wand-like electronic device to detect termites within stations without opening or disturbing them.


FirstLine® is another bait product option, manufactured by FMC Corporation (Philadelphia, PA). Installation and servicing procedures are fairly similar to those for Sentricon. FirstLine bait stations have a somewhat different appearance, and the corrugated cardboard food source contains sulfluramid, a compound that interferes with the termites’ ability to derive energy from food.

Most pest control companies using FirstLine also perform a partial or full liquid treatment. (Sentricon is often used as a “stand alone” installation). Research studies evaluating the effectiveness of FirstLine have been more limited, and there is uncertainty as to whether the bait or the supplemental liquid application is having the greater impact on the termite infestation.

EXTERRA™ Another product used by some companies is the Exterra™ Termite Interception and Baiting System (Ensystex, Inc., Fayetteville, NC). The bait used in Exterra contains diflubenzuron, a termite growth regulating agent in the same chemical group as Sentricon’s active ingredient, noviflumuron. Both compounds are chitin synthesis inhibitors and kill by disrupting the termite molting process. Installation procedures are similar to Sentricon and FirstLine, but subsequent servicing of stations may be a bit less frequent (45- to 90-day inspection intervals rather than initial visits that are monthly). As with Sentricon, Exterra is marketed as a stand-alone baiting system with no supplemental liquid treatment required. Fewer independent research trials have been conducted with Exterra, making it hard to say whether the products are comparable in overall performance.

SUBTERFUGE® Subterfuge is a relatively new termite bait manufactured by BASF Corporation (Research Triangle Park, NC). The active ingredient, hydramethylnon, affects termites in a manner similar to sulfluramid, the ingredient in FirstLine. Unlike other systems on the market, no wooden monitors are used prior to installing the baits, which are inserted from the outset. There have been few published studies evaluating the bait’s effectiveness.

ADVANCE™ TERMITE BAIT SYSTEM This new bait system employs the same active ingredient (diflubenzuron) found in Exterra. Installation and servicing intervals are similar. Advance and Exterra both have station designs that reportedly allow termites to transition more readily into the bait after initially feeding on wood monitors. Independent evaluations of the bait’s effectiveness are still rather limited.


TerminateTerminate Box
This bait product, sold in retail stores, is marketed specifically for use by homeowners. The Terminate™ Termite Home Defense System consists of small, 4 by 1-inch hollow plastic stakes provisioned with sulfluramid-treated cardboard (the same ingredient in FirstLine).

The baits are installed at various locations around the outside of the home and inspected periodically by the property owner. The treatment cost for a box of Terminate bait stakes (under $100) is tempting, considering that a professional treatment using bait or liquid can cost well over $1000. There are issues pertaining to use of Terminate, however, and it is questionable whether it will protect a home from termite attack. As part of a 1999 settlement with the Federal Trade Commission and several state Attorneys General (including Kentucky), product directions now state that Terminate is not recommended as a sole protection against termites. Moreover, for active infestations the buyer is advised to get an inspection and treatment by a professional.

Successful termite baiting requires proper installation, monitoring and bait replenishment, plus ongoing surveillance of the structure. When using baits, supplemental treatment measures also may be necessary. For these and other reasons (see ENTFact-642, Do-It-Yourself Termite Baits: Do They Work?), baiting is usually best left to professionals.


This is the most common question from homeowners trying to decide which form of treatment to purchase. The question is a difficult one with no simple answer. Factors to consider in the purchasing decision include:

Are you opposed to having your floors and walls drilled, or furnishings moved? Homeowners considering a bait treatment are usually relieved to learn that their carpeting won’t have to be rolled back, their floors extensively drilled, or furnishings moved, as is often the case with conventional liquid applications. The technician may not even need to come indoors to install or monitor the stations. Drilling noise, concrete dust, application hoses, and similar disturbances are avoided.
Are you opposed to having pesticides applied in and around your home? Conventional liquid treatments utilize hundreds of gallons of termiticide, injected into the soil under and around the house. Health and environmental risks from such treatments are generally considered negligible, but some householders still are apprehensive. With baits, the amount of pesticide applied is minute and confined in tamper-resistant stations.
Are there construction features that make it hard to treat with a liquid? Some buildings have wells, cisterns, nearby ponds or streams, plenums, sub-slab heating ducts, drainage systems, inaccessible crawl spaces, or other features that complicate treatment of soil with a liquid. With baits, such conditions aren’t a problem and may be the only feasible form of treatment. Houses that were unsuccessfully treated with liquids also are candidates for baits, since they do not require gaining access to hidden or hard-to-reach areas.
How quickly must the infestation be eliminated? A limitation of all termite baits is that they are relatively slow acting compared to the effects of liquids. Several months may pass before termites find the baits underground and distribute them to their nestmates. Consequently, the elimination process can take several months or longer to complete, and a degree of feeding and damage may occur before the bait takes effect. Homeowners with a severe termite infestation or those involved in a real estate transaction may not want to wait this long — preferring instead that a liquid be applied alone or in combination with baits.
How much are you willing to spend for treatment? Termite services vary in price from about $700 to $2500 for initial treatment, and $70 to $350 for the annual renewal warranty in case termites return. Baiting often is more costly than liquid treatment because the process requires several visits to the structure to monitor for termites, and add or replenish baits. Homeowners should consider both the initial treatment price and the annual renewal fee in making their purchasing decision. Whereas liquid treatments usually entail an annual followup inspection, bait renewals typically require three or four visits per year, for as long as the contract is in effect. Thus, the annual renewal fee for baiting may be two to three times higher than for liquid treatments. Failure to maintain the annual renewal agreement can be a prescription for disaster with baits, since there is no residual pesticide left in the soil after the termites have been eliminated. Ongoing structural protection depends on monitoring for the possible return of termites in the future.
In summary, termite baits are useful and effective tools for managing infestations. Regardless of which product/system is used, they will not work by simply hammering a few stations into the ground and walking away. Success will require thoughtful installation and diligent monitoring by an experienced technician, backed by a responsible pest control firm.
