Termite Infestations cause millions of dollars in damage each year to timber-in-service. Termites are a problem in most parts of Australia but they are particularly active in hot wet areas such as Cairns and Coastal Qld.
Homeowners and contractors must realize newly built homes represent large investments, and the cheapest method of termite management may not be the best or most appropriate method for their specific site requirements.
There are several methods available to treat subterranean termites. A chemical treatment is the most common treatment type available for subterranean termites. The goal of a subterranean termite chemical treatment is to establish a continuous termiticide barrier between the termite colony (usually in the soil) and timber in a building. This is done by placing termiticide in the soil around the foundation elements to provide a barrier preventing termites from entering the structure. Technicians trench the soil and inject termiticide beneath it. This creates a protective barrier around the property.
In-ground baiting systems are also becoming a popular method for treatment of subterranean termites. A subterranean termite baiting system involves placement of cellulose (wood material) bait stations at strategic locations around the perimeter of the home. Worker termites, which constantly forage for wood to feed their colony, locate the cellulose bait stations and leave special scent trails to summon their mates to the food source. The cellulose material in the bait station is then replaced with a chemical inhibitor, retarding the molting process in termites and preventing them from growing. The carrier termites then bring the chemical back to the colony and–if everything goes well–spread the inhibitor throughout the remainder of the colony. Because of the growth inhibitor, the carrier and the rest of the colony will die.
