Many buildings Ecosan has inspected over the years have been previously treated with some method for the control of Borer. Usually by a previous owner.
Often there are indications of Borer activity and at first observation the Borer appears inactive, as if the previous treatment has been successful.
However quite often when our technician’ venture deeper into the crawlspace of the ceiling or the under site it becomes evident that Borer is indeed active in the furthest most perimeter of the site.
Why is this?
Often the reason behind this occurrence is not because Borer prefers these areas, rather, the previous company or their employee failed to properly access these areas during the treatment. Of course it is very difficult for the client to gauge the success of the work solicited as they do not have the knowledge or seldom inspect these areas of their building. Also they are not onsite during the treatment due to health and safety laws. It is very difficult even for a professional to confirm if areas have been correctly treated. Only the technician doing the work has this knowledge.
It is not uncommon for technicians to enter into the roof void or the crawl space and utilise a blower type machine which pushes the active ingredients into the air space. This treatment is suitable for spiders and other insects and sometimes shorter term Borer treatment. However it is not suitable for professional Borer treatment.
These methods are however common and much faster than the appropriate methods. Also using less chemical outlay, they present an attractive option for some operators.
It is in the best interests of the home owner to ensure proper methods are used during treatments to avoid a false sense of security held in the treatment company.
