Understanding Structural Fumigation

When dealing with pest infestations in a property, the use of termiticides, physical and chemical barrier systems and baiting methods are a commonly effective way to get rid of pests. There are instances, however, when pests are hidden within walls and other areas that cannot be easily reached with the use of such treatments. And when spots of infestations are missed, pests can continue to multiply and damage the property unnoticeably, mostly resulting in expensive repair costs. At Defence Pest Management, when there are signs of pest activities in walls, hidden areas and other inaccessible sections of the structure, our technicians will recommend the implementation of structural fumigation to ensure that every part of the property is treated. This reduces the risks of leaving pests behind after a treatment has been carried out.

What is Structural Fumigation?

Structural fumigation is the use of a tarp or, more commonly, a tent to enclose a structure or house so that gaseous pesticides, known as fumigants, can be released in the area in order to get rid of pests. Because the fumigant is trapped inside the enclosed area, this kills even those pests residing inside wood materials. The sealed structure and gaseous pesticide is left for a few days, allowing the fumigant to effectively suffocate the pests within. If the fumigation is done too quickly, there is a chance that drywood termites and woodborers might not be completely eliminated. The period of fumigation can vary depending on the size of the structure and the type of fumigant used. In most residential properties, the complete process of structural fumigation can take about a week.

Knowing When You Need Structural Fumigation

To help you decide whether you require structural fumigation for your property, Defence Pest Management can first inspect it for the presence of pests that may not be readily eliminated with the use of barrier systems and baiting methods. The inspection will also determine the location of infestations, degree of infestation and potential risk areas that might be used by pests as entry points.

Does Structural Fumigation Cause Safety Hazards?

Because fumigants used in structural fumigation are meant to be poisonous, it is necessary that safety measures are put in place for the safety of the residents of the property, their neighbourhood and the technicians carrying out the fumigation. All appliances and electrical equipment in the property must be turned off and unplugged, including the main power switch. Pets and indoor plants must be taken out of the property, and food should be stored in sealed containers. Neighbouring residents also need to be informed prior to fumigating the property so that entry can be avoided. In general, structural fumigation is a safe process as long as preventive measures are implemented and the process is handled by a professional technician.
