Chemical for termite control






1)When are termites most common?

Once a colony is established, termites are a year-round problem. However, there is an increase in colony expansion activity during warm weather such as that of Malaysia.


2) How many types of termites are there? Which type of termite is most active in Malaysia? 


There are three main types of termites. They are the dry wood termites, mount building termites and the subterranean termites (white ants). The Dry Wood termites are not very common in Malaysia. They are normally found in dry wood and therefore may live above the ground level. The mount making termites are mainly found in the forest. They live in mounts and are quite easy to detect. The most commonly found and feared specie is the subterranean termite. They live in nest below the ground. Therefore, it is not easy to detect their nest.


3) Can you provide some information on subterranean termites ?


Subterranean termites lives in colonies beneath the ground. Their favourite food is rotten wood which is soft and easy for them to chew. Therefore the most common areas that are attacked by them are the door frame of the toilet and the window frame of the kitchen. They eat almost anything to do with wood such door frames, parquets, wooden skirting, wood beams, tree trunks, newspapers, clothes and etc. They have even been known in some instances to eat plastic as in wires causing short circuit to the building.

Subterranean termites are quite shy by nature and therefore does not come out openly. They are mostly hidden behind or inside the wood or concrete. When they need to move across an uncovered terrain, they will construct mud tunnels to enable them to move around unnoticed. Like ants, they foray outside their colony in search for food to bring back to feed the queen and colony. Termites like ants and bees share a common structure in hierarchy. They have a Queen whose job is to mate and lay eggs. Then there are the kings that mates with queen. Beside that there are some spare queens which will assume the role of the queen when the current queen is dead or missing. Next are the soldiers guarding the colony against their enemies. The rest are workers that search for food and build nests. Those termites that are normally seen in the house are the workers termites. Among them are a few soldiers on guard to protect the workers against attack by their enemy such as ants.


4) There are lots of wood dusts around my kitchen door frame, is it a sure sign of termite infestation?


If the door frames are not hollow, and there are tiny holes around, there is a possibility that Wood Borers are the culprits. Wood Borers made holes in the wood but are not as destructive as termites. To be sure, call us for a free inspection.


5)There are lots of sands dropping from holes in the wall. Is this sign of termites infestation?


Termites have mud trails / tunnels for them to move from one place to another. They do not carry sand around like the ants. In fact the sign of sands is a telltale sign of ants. Ants are not as destructive as termites. They live on plants, existing holes in concrete walls and built their nest in the ground. They do not chew on woods.


6 ) What are the methods of pest control available for subterranean termites?


There are currently three methods available. Others are a combinations of these methods.

  1. Spraying of termiticide on the affected areas. This method involves the spraying of chemical over the affected areas. The termites on contact with the chemical will be eliminated. However, those termites that have not been sprayed onto will continue to cause damages to the property.
  2. Dusting or powdering on the termites by the use of a hand held pump / puffer. The purpose of this treatment is not to kill the termites on the spot but to let the termites die gradually in a week or two. This is to enable the affected termites to go back to their colony and die there thus affecting the whole colony. When this happened, the whole colony will eventually be eradicated.
  3. Slab injection treatment to form a barrier of chemical beneath the premises. This method is similar to pre-construction soil treatment. In fact, it is a corrective soil treatment. It involves drilling of holes (around 1.5cm in width) at an interval of 18 inches around the perimeter of the building. Then the chemical are pumped into the floor beneath the slabs through the holes drilled. The main purpose of this treatment is to form an unbroken chemical barrier beneath the building. This is to prevent the termites from entering the building. 
  4. Baiting and monitoring system to eradicate the whole colony of termites without any drilling. The holes drilled here are around 4-6 inches in width. In all there will be around 10 to 20 holes drilled. Wood are placed in a container inserted into holes. The holes would be monitored regularly to detect any termite infestation. Should termites be detected, the wood would be replaced by treated baits. When the termites (workers) attack the baits and feed the colony with them, the whole colony could eventually be eliminated. However, the absence of termites hit does not denote the absence of the termites. Some termites species are known to avoid these 'foods' preferring their normal food of rotting tree roots or trunks.
  5. There are no 100 % fool proof termite system just as there are no perfect human. Theoretically, the best system is to do soil treatment before a building has been build. Obviously, the next best would be to do corrective slab treatment as it is trying to correct the soil by treating it after the building is already in place. Of-course there is the disadvantage of having your favourite marble floor drilled and the noise that comes with it. Thus, making baiting system an obvious choice for those who can afford the treatments. However, it is a well known fact that baiting system does not always work as some species of termites have been known to avoid the baits. Furthermore it will be rather inconvenient for the house owner to be tied down by having weekly or fortnightly monitoring of the baits by pest control operator. The baits must also not be placed near the normal food source of the termites as the termites will definitely be more inclined to eat the rotten tree trunks and roots than the pieces of wood placed in the container. Dusting treatment is also very popular and works reasonably well in the eradication of termites. It is normally used when drilling is not possible or allowed. Together with the normal spraying, it is a cheap yet effective substitute for those who cannot afford the baiting system. It can also be used in conjunction with drilling and spraying as in corrective slab injection treatment. 


7 ) If treatment is done correctly, how long will the insecticide barrier be effective?

Before chlordane was taken off the market as a termiticide in October 1988, it was the most widely used product for termite control because of its long-term effectiveness. In fact, a house could be protected for 20 years or more using chlordane or like products. Chlordane was taken off the market because of misuse. The termiticides used today for termite control are much less persistent to the environment. With the products today, you should expect a properly applied termite treatment to protect your home for five years.

According to Pest Control Association of Malaysia, the recommended warranty period are as follows:

  1. Pre-construction Anti Termite Treatment (Soil Treatment) for new building under construction – 2 years from date of completion of first treatment.
  2. Post-construction Anti Termite Treatment (Corrective Slab Treatment) for existing building – 1 year from completion of treatment.

However, individual companies in Malaysia will provide warranty from 1-5 years.


8 ) My next-door neighbour has termites and is going to have his house treated. Are the termites going to attack my house next?


Termites move randomly through the soil searching for a source of food (wood). So, they don't know where your house is exactly. If your next-door neighbour treats his home for termites, your house isn't automatically the termites' next meal. Your house does not need to be treated; but, if there are active termite infestations in your neighbourhood, it is a good idea to have it inspected. If you can afford, doing a corrective slab injection with warranty of up to 5 years is a cost effective option to consider. Prevention is always better than cure. Imagine the cost of damages if left untreated. Your door frames, parquet flooring, expensive furniture, ceilings, wood beams, speakers, expensive clothing and etc will definitely cost more than the treatment. In some extreme cases, the termites can cause a short circuit by eating the plastic covering the live wires.


9 ) What is "Pre-Construction Anti -Termites Treatment"? How is this different from "Post Construction Anti-Termites Treatment" or Corrective Slab Injection Treatment?

Pre Construction Treatment or Soil Treatment means treating the soil under the structure before concreting. This will only be possible for new houses under construction. Post Treatment and Pre Treatment would be the same the method of treatment, amount and kind of pesticide used, and methods of application are the same, unless drilling would be needed as in a ready built house.


10) How do I know I am getting the right company to treat my house/premise?


a) Do Not use a one man pest control operator. One person doing a slab treatment is almost next to being impossible. The same apply to company without the proper equipment or manpower.

b) Do not go for the cheapest price. I was told by a client that a certain company is charging RM500.00 for a corrective slab treatment. I am wondering what kind of chemical is being used. Reasonably good chemical such as Landtrek (20 liter), Premises (1 liter), Cyren and others cost from RM500.00 to RM800.00. What about the workmanship, the drill bit, the warranty and etc.??? Even if you get 10 years warranty, they might disappeared out of sight. The warranty from an established company is far more valuable than that of a newly established company. Never treat them as the same!!! You might have to pay the price of having to retreat the whole premises again using a more established company. The chances for an established company (with more than 5 years) to close down is much lesser than a newly established company even if it is bigger and look solid. Due to their inexperience in managing the company, many new companies and/or pest control operators close down within the first few years.

c) Do not assume all the chemical are the same. Some of my clients on seeing the white colour liquid would assume the chemical used is the same. I used Landtrek for my treatment and is more expensive than the average chemical for termites. For instance, Landguard, Cyren 2 and etc have higher level of active ingredient chlorpyrifos of 38.7% in comparison with Termiban, Pestban, Logic and etc. which have chlorpyrifos level of between 19% to 21.2%. Therefore, the prices of Landguard will definitely be higher than Logic by  about RM100.00-RM150.00. The price difference between a better known brand such as Landtrek and Cyren 2/Landguard is about RM100 to RM150.00 even though they have the similar level of chlorpyrifos at 38.7%. Always compare an apple with an apple.

d) Understand what you are paying for and why. For instance a more established company will quote more than the average. A double storey house normally cost around RM3,000.00 to treat. Inside this cost are i) managerial perks ii) staff costs iii) better chemical cost iv) double sided drilling v) brand goodwill. Most big company charge by the number of holes drilled and therefore have to drill as many holes as possible. We just quote by lump sum and therefore does not require unnecessary drilling. For the same reason, a branded computer will definitely cost more than one assembled in the computer shop in Mid-Valley. Smaller company like Pan Environment Technology Sdn Bhd does not have to burden their customers with unnecessary costs. We assure you our price is competitive and reasonable. We provide you with quality services and reasonable prices.


11 ) What is the best termite chemical available now for termite treatment?

There is not much difference between the effectiveness of the various termite chemicals on the market, when they are used as directed on the label. However, it would be wise to notice the active ingredient of the termiticide used. For the active ingredient
Chlorpyrifos, the percentage for a reasonably suitable termiticide is around 38.7%. Those chemicals with around 20% Chlorpyrifos is about half the normal strength and therefore half as effective. Chlorpyrifos belongs to the Organophosphorus family of nerve poison and is more poisonous to vertebrates than other classes of poison. It inhibit or tie up certain vital enzymes of the nervous system such as chlolinesterse (ChE). This will result in the accumulation of acetylcholine (ACh) neuron and muscle junctions causing rapid twitching of voluntary muscles and finally paralysis. Chlorpyrifos can kill the termite within seconds on contact and can be a good barrier to prevent the entry of termites since it is smelly and poisonous.  

The more expensive chemicals such as Premise 200SC are normally more environmentally friendly and belong to a lower class poison. The active ingredient is Imidaclorprid  at 18.3% and the balance solvent. Imidaclorprid is from the Nicotinoids family of tobacco based poison. It is a systemic chemical that can kill the termite on contact. Even on minimal contact, the termite could lose its ability to do grooming. As the soil is normally damp, fungi will attach to the termites. Losing the ability to groom will caused the fungi to eat into the termites and kill them. One liter of Premise 200SC can be used to treat an area of 80 to 160 meter square. The cheaper alternative such as Landguard/Cyren will require 10 liters for the same area. Therefore, Premise 200 SC cost about twice that of the cheaper chemicals. We would recommend the higher dosage which should easily provide protection of up to 5 years. Many company are actually using the lower dosage to charge cheaper prices.

However, you must be aware of some small company especially a one man show offering cheap treatment. The chemical used by them might not be suitable for termites. Refer to 10c.


The most common reason that a chemical / barrier treatment fails is when the application results in an incomplete insecticide barrier around the structure.

This is due to the following reasons :

A) The termiticide is diluted with too much water.

B) The termiticide is not injected deep enough (all the way to the footings of the basement).

C) The volume of termiticide was insufficient.

D) Treatment procedures are not carefully followed to ensure proper coverage.

E) The chemical used is not suitable (i.e. a) using chemical with active ingredient of around 20% Chlorpyrifos b) using chemicals not for termites c) chemical is diluted with diesel, kerosene, petrol and etc.)

F) The technicians does not have sufficient or proper equipments to perform the task. Instead of using a power sprayer, the one man show will only have a normal sprayer. When there is clay, the normal spraying will not be able to penetrate the layer of clay.

G) The technicians does not have sufficient or proper experience and knowledge to perform the task.


Please note that as from 2008, we have ceased to use Chlorpyrifos for soil treatment and slab injection treatment. We are currently using imidaclorprid based chemical for termite treatment. Chlorpyrifos will only be used for residue spraying of homes or offices that feel safer with the smell of the chemical.
