Baiting involves placing bait tubes or traps in the ground at intervals around a building -several dozen for a typical house. Pieces of untreated timber or other cellulose-based material are inserted into these tubes as bait for termites. The tubes are monitored and, when termites are observed feeding on the bait, it is replaced with treated bait containing a chemical that the termites then carry back to the colony. The chemical is slow acting, so termites are unable to associate its source with its effects. Over a period of several months, the entire colony may be destroyed.
The series of galleries (area hollowed out) created by termites in wood give a honeycomb appearance. These galleries follow the wood grain. Interior galleries contain greyish specks of excrement and earth, called frass.
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.
Termites often enter buildings through cracks and holes and expansion joints in foundations. Spaces around piping and wiring are also points of entry. These openings may be filled with either roofing-grade coal-tar pitch, sealers or similar commercial caulking products.
It is one of the most economical ways to get rid of termites. It uses termite products like termidor as a barrier. Fripnoil is an active substance in termidor. It attracts the termites towards itself and termites that enter the affected area die slowly.
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 damage to wood is usually not noticeable on the surface, as the termite avoids exposure to air. Therefore the exterior surface of the wood must be stripped away to see the damage.. Termites do not reduce wood to a powdery mass, or push wood particles to the outside as do some wood-boring insects, such as carpenter ants and powder post beetles.
Termites have a very thin cuticle (skin) and are subject to rapid desiccation (drying out) if exposed to the environment outside their enclosed habitat. In order to maintain a highly controlled environment, termites must live in a closed system. Colonies in wood are always contained within an outside shell of cellulose material. In this way, they are protected from exposure to the outside.
Conventional treatment for termite control requires the services of a licensed exterminator. Several firms in Ontario are qualified, and your Yellow Pages or a Local Search will assist you in locating companies in your area.
Smaller versions of termite barriers, a termite services company will set bait stations in the ground immediately around your home. These small boxes filled with poison can help rid your home of termites as it attracts and poisons them. You termite services company will replace them with new bait stations when they begin to lose their effectiveness. Bait stations have become an increasingly popular way to control termites. The key is placing the bait stations in the most effective locations, so it`s best to contact an expert for placement and installation.
