The most common form of termite infestation comes from subterranean termites. These termites build their colonies below the soil or around any structure that promises them a source of food. Termite barriers can help to prevent such infestations.
It has now become almost mandatory all over the world for new constructions to have termite barriers in place, so that the destruction that these pests can cause is avoided. Barriers can be chemical or physical.Chemical barriers are those in which chemicals that are harmful to the termites are mixed with the soil in the foundations and around walls to deter termites from entering the property so treated. Once a building is completed a residual insecticide is sprayed all around the perimeter to act as a final deterrent.
Physical barriers can be concrete slabs or ultra marine grade mesh made from stainless steel that prevents termites from crossing them. This physical barrier is considered environmentally friendly as most insecticides used are considered harmful to humans as well. Glass and granite particles can also be used as physical termite barriers.
Both these forms of barriers can be breached, especially if due care is not taken to ensure that the barriers are not installed in the correct fashion. Barriers can also deteriorate over time, and inspections for termite are a must and need to be constantly done if this infestation is to be avoided. Areas around the property must constantly be inspected to detect any signs that indicate the presence of termites. Termites are also capable of bridging physical barriers and use other means to gain access to a building.
It is advisable to have professionals inspect your home at least once or twice a year and take necessary preventive action to prevent any termite infestation. Any nests noticed in surrounding areas must be destroyed so that the colonies do not build up again.
