The first one, liquid soil treatment is one of the oldest and most effective methods of termite treatment. In this type of treatment, one needs to consult a professional who would apply an insecticide along the walls of the house.

This liquid insecticide sinks into the ground, creating an odourless barrier around the house. This method of treatment requires a minimum of 5 years.

The second one involves installing the baiting stations in the ground. In this method, the bait containing termite food (cellulose, paper and cardboard) and a slow-release chemical is implanted in the ground at a distance of three metres.

This process is effective but it takes a significantly longer time to see results. This method of treatment requires around 8 to 12 months.

The third method, the DIY method, involves implementing the above methods at home. This method is relatively easy due to the requirement of minimum equipment and easy- to – follow expert guides.

One can also control termites by the physical termite barrier technique, which keep termites away from home. Although these barriers can last for up to 20 years, they are less effective in comparison to the chemical barrier. It should be used as a prevention.

Termidor HPII is a termiticide used for continuous and highly infested zones. This method can be easily done in three months. This is the most effective due to the requirement of less maintenance, low retreat rate. It is even cheap.

The termite professional should also be able to reach all the wooden components of the house to shorten the duration of treatment.

The effectiveness of these treatments lasts from few months to around 10 years. While the bait stations technique should be done once in few months, methods like liquid soil treatment should be done once in 5 years. On the other hand, Termidor HPII can be done once in 10years.

The expected lifetime of any treatment depends on the treatment type used, chemicals and materials used, and the person who performs the process. Hence, it varies from place to place and from person to person.
