How Long Does A Termite Barrier Last?

The life expectancy of termite treatments varies depending on the type of treatment and who installed it. The key to a long-lasting termite barrier is proper preparation. Read on to learn more about termite barriers and how long they last.

Chemical Termite Barriers

A high-quality chemical termite barrier can cover an average house of 70 linear metres. This type of barrier is designed to last up to a maximum of 8 years.
 
Lower quality chemical barriers may be cheaper, but they will usually have a shorter life expectancy. Recent advances in technology have enabled the production of more efficient and effective chemical barriers that have less of an impact on the environment.
 
Between 2001 and 2004, new legislation stipulated that chemical treatment could not be used on a new build house unless the chemicals could be reapplied over time to maintain effectiveness. This option was very costly for builders, so the physical termite barrier became more popular.

A physical termite barrier is made from plastic and is installed around a house perimeter during construction. It lies against the brickwork, and they are a mandatory part of the current building code for all homes built after 2001. These systems have an average lifespan of 20 years.
 
A single crack in the perimeter can allow the termites to get in, so it is important to check and maintain the physical barrier. Conversely, a chemical barrier is designed to eliminate the termite colony as it travels through the soil.
 
Both options reduce risk, but chemical barriers are the more effective option.

Termite bait stations operate as early warning indicators. They enable homeowners to act before any damage is done. Typically, they must be checked and replenished every month. If active termites are found, a new bait using an insect growth regulator is added to wipe out the colony.

Some chemical barriers are advertised as having longer lifespans (such as 10 years, for example). You should always look closer, however, since these sometimes lack key features. For example, a chemical barrier with a longer lifespan may only be a repellant, rather than eliminating the colony.
 
Always opt for high-quality products for the best results. The damage that a colony of termites can do is severe, so the extra cost is worth it to get maximum protection. The actual cost varies depending on which type of barrier you choose and the proportions of your home.
