Expert Termite Barriers That Work
Termite treatments using chemical soil barriers around the perimeter of the property is regarded as the most effective termite pest control available on the market.
Once a favourable result has been achieved by the use of a termiticidal dust, a chemical soil barrier can be installed around the perimeter of the structure. It is now universally accepted that trenching is the most thorough method of installing a termite barrier, this includes concrete areas such as paths, patios and driveways.
The single biggest area where termite treatments fail, is when drilling and injecting through concrete has taken place. It is always our recommendation that a treatment strip be cut into all concrete areas along the perimeter of the house. This allows the soil replacement technique to be used, that is, where the soil below the concrete areas can be excavated and replaced with a clean soil or loam mix. This method of treatment ensues two things. Firstly, the treatment or chemical barrier has a longer life expectancy (that is, what the manufacturer has deemed as the life expectancy of their chemical product). Secondly, it creates a complex barrier around the property.
Where this method of treatment is declined by the customer (and drilling is requested), then the limitations and limited life expectancy of this method of treatment must be accepted by the customer.
The photo above shows treatment strips formed by cutting concrete & lifting pavers, it is virtually impossible to treat areas under, around or below pipes that are beneath the concrete areas.
These photo to the right revealed termite entry points into two separate houses after drilling treatments failed. Paths have had to be removed or cut & entry points located to stop repeated infestation. A chemical barrier was later applied using soil replacement to successfully stop any further termite infestation.
