WHY ANTI-TERMITE TREATMENT NECESSARY FOR BUILDINGS
Q 1: Is it for saving the Door & Window Frames only?
Ans 1: Not at all.Sometimes you may see thin mud tunnels (See the images below) in walls, electrical wiring, in the corner of rooms etc. These are the path ways of Termite and be confirmed that your building has been infested with Termite.Generally we crush those and sweep away the spoils without thinking about the source of this amount of soil. This raw material of building the tunnels are brought by the Termites nesting below you building. Their nest may be below the foundation or the floor or outside . But the mud for tunnels are carried by soldier termites from a nearest location within your building. However for surviving they will make tunnels for marching in search of food. And on locating you will seep away the spoils without taking into account the quantity of soil. In this way in course of time a void will be created in the earth below your building. Now in the recent times the frequency of Earth Quakes is increasing due to various geographical imbalances and naturally our buildings are facing considerable units of tremors. So any void creation in the soil below your building may end up in a disaster.
Q 2: Is it for saving the Furniture and Fixtures?Ans. 2: Furniture and Fixtures will be the secondary target of the Pests. The Primary target will be the contents. It has been reported that, after returning from a small vacation of seven days somebody found costly clothes in the wardrobe have been eaten up. Materials containing Cellulose is their good food. Similarly they can destroy your valuable collection of books. Dry wood termites will destroy the furniture.
Q 3: In which areas Termites are very active?
Ans.: As the termites can not survive in a dry weather, so they are most active in the soils containing moisture like Morum Soil. That's why from Panagarh to Barakar in West Bengal, India is marked as a Termite Zone.
Q 4: Why Termite attack is not visible within 5 - 10 years of the construction of the Building?
Ans. 4: The Termites living below the soil of building can survive 5 to 10 years consuming the left out cellulosic materials i.e. pieces of wood of shuttering planks, clothes etc. during construction. Naturally they emerge out in search of food after 5 to 10 years and become visible.
Q 5: Which one is more effective Pre-Construction or Post-Construction?
Ans: Anti-Termite Treatment is basically creating a Chemical barrier between the soil below and surrounding of your building. Pre-construction Treatment starts from the excavation of trenches for foundation and soaking of chemical by the soil is visible. In Post-construction Treatment soil is treated through drilled holes and soaking of chemical by soil is not visible. Hence Pre-construction Treatment is more effective, dependable and genuine preventive measure for Termite infestation.
Q 6: What is the expected Cost?
Ans: In comparison to the cost of construction of a Building, cost of furniture & furnishing, cost of favorite books of your library, and valuable documents, the cost of these Treatments are very negligible. It is easily affordable by any individual who can buy or construct a building.
SOMETHING ABOUT TERMITES
On the basis of their habitat, termites are divided in two types:

(1) Ground or Soil nesting i.e. Subterranean & (2) Wood nesting i.e. Non-Subterranean having no contact with Soil or Ground. Both the varieties are dangerous but the Subterranean or Ground nesting type can heavily damage a building, if allowed to infest highly. Termites develop colonies below the ground of the building or sometimes at close vicinity of the building they make nest in the stump of any tree and some species even make a conical or dome-shaped mound. These colonies may persist for many years. Cellulose, a polysaccharides is the chief constituent of all plant tissues and fibres and cellulose is the basic nutrient of Termites. So Termites reaches the building in search of their favourite foods i.e. wood. They also damage materials of organic origin with a cellulosic base, household articles like furniture, furnishings, clothing, stationary etc. Termites are also found to damage non-cellulosic substances in their search for food. Rubber, leather, plastics, neoprene and even the lead cover of underground cables are damaged by termites.
Subterranean termites require moisture to sustain their life. They normally need access to the ground at all times.They build tunnels with clay between the nest and the source of food for their movement in a humid atmosphere and darkness. These tunnels also protect them from predators.
IDENTIFICATION OF TERMITES:
There are over 2300 species of Termites out of which about 220 are found in India.
The insect pest is also known as "White Ant", but they are neither white in colour nor are they Ants at all. Though partially resembling true ants, they are different in structure and metamorphosis. Termites constitute a separate order of insects called "ISEPTORA" (in Greek ises means 'equal' and pteron means 'wing'). Termites have four equal wings whereas the front pair of wings of Ants are longer than their hind pair.
A Termite colony consists of a pair of reproductive, the so called king and queen and a large number of sterile workers, soldiers and nymphs. Few people believe that, termites can be controlled by destroying the queen. But in reality the colony can never be destroyed by removing the queen because when the queen is lost or destroyed, a number of supplementary reproductives take her place in some group of termites. All the works of the colony are carried out by the workers. Soldiers guard the colony. The adult workers and soldiers are wingless. The workers are generally grayish white in color. The soldiers are generally darker than the workers and have a large head and longer mandibles. There are however, other types of soldiers whose mandibles are small, degenerated and function-less, instead, their frontal part of head is prolonged to form a long nasus through which they squirt out white poisonous fluid to dispel the enemy.
The reproductives i.e. the flying adults, have brown or black bodies and are provided with two pair of long equal wings. At certain periods of the year, particularly after a few warm days followed by rain, these winged adults emerge on colonizing flights. This swarming, also called the nuptial flight, may take place during the monsoon or post-monsoon period.The flight is short and most of the adults perish due to one reason or the other. The surviving termites soon find their mates, shed their wings and establish a colony if circumstances are favorable.The female of the pair or queen produces a few eggs in the first year. The rate of reproduction, however, increases rapidly after 2 to 3 years. Yet a very little damage is found in a period of 5 to 10 years i.e. before their highly infestation at the site. In Bengali these winged insect pests are called "Badla Poka" or "বাদলাপোকা " So wherever you find these insect pest you may conclude the existence of Termite colony close to or below the ground of the building.
