It is important to be informed of what is the standard if you decide to go ahead with chemical barriers. It seems many people are being mislead into believing they are required to have annual top ups of the chemical barrier a few rooms per year, this is not the necessary.
Chemical barriers do need to be topped up or reapplied around the entire home, but the time frame depends on the life expectancy of the chemical being used.
At Termite Free Naturally we do not use chemical barriers, instead we use a trapping and
baiting system that eradciates termite colonies for good.
