The second method is called "budding". In this method, when a colony becomes sufficiently large, or a portion of a colony becomes separated from the main colony, new secondary reproductives are formed from larvae or nymphs and the nucleus of a new colony is established.
Soldier termites are similar in size and colour to workers, but have an enlarged brownish coloured head with large modified mandibles (large biting jaws), used for defense.
Foundation walls and slabs should be designed to inhibit the entry of termites into the building, and to facilitate inspection for shelter tubes. Sheet metal and steel mesh barriers properly designed and installed, are also an effective means of control. Wood products and other building materials should be selected with regard to termite resistance.
The presence of shelter tubes over the surface of foundation walls is the primary sign of a termite infestation. These tubes are 6mm (1/4 inch) to 12mm (1/2 inch) wide, and can extend many centimetres in length until wood is discovered. These tubes protect termites form the drying effect of air, and maintain the termites` contact with the soil.
The subterranean termite is very closely associated with the soil, which is its main source of life-sustaining moisture. Termite food consists of cellulose obtained from wood and wood products. Decaying damp wood is preferred but termites are also able to feed on sound, dry lumber.
Proper ventilation is essential to eliminate moist conditions. The main areas of concern are verandas and crawl spaces. The amount of ventilation will be variable according to regional and local factors, and must meet building standards.
The female reproductives may thousands of eggs. These eggs hatch and pass through an immature stage (larvae) before finally differentiating into either a worker, soldier or reproductive caste.
Subterranean termites were first reported in Ontario at Point Pelee in 1929. It has subsequently been reported in Toronto (1938), Windsor (1950), Kincardine (1954), Oxley (1955), Amherstburg and Dresden (1968) and Guelph (1975). Presently in Metropolitan Toronto, the termite infested area extends through a radius of approximately 30 kilometers.
The worker termites are white in colour and approximately 6mm (1/4 inch) in length. Their antennae are straight (not elbowed) and the body is not narrowed at the waist, which distinguish them from ants. They have chewing mouth parts and are responsible for foraging and feeding the dependent members of the colony. The hind gut of the worker contains protozoa (single-celled animals) which assist in breaking down cellulose into its component parts which are digestible by the termite. The worker termite causes the structural damages.
This system is installed in the outdoor of your property. As wood attracts termites, these systems have wooden base. As the termite approaches the wood, a poisonous lace replaces it on which the termite feeds. Now, termites carry this poisonous food to the whole colony. It is a termite capture device and is available on many stores.
