Fumigation is the most usually used method for pest control and abolition. It involves the use of pesticides or pest retardants in steamy form, referred as fumigants, to poison pests in a housing area, commercial complex or public space that has been infested. Fumigation is also used in farming or grain harvest to prevent the soil being infected or during import and export of goods to get rid of insects, worms and beasts that might be transported from place to place. While extreme use of chemicals in any form is to be escaped because it may harm human life or essential buildings, the process is not totally effective in pest elimination, it merely prevents the vermin making their attendance once again in the same area.

Process:

The fumigation procedure is typically done in a phased manner. As a first step, the whole area that requirements fumigation is sealed off or covered. Next, the area is fumigated, i.e. the elements are released in the enclosed space which may be a home, an office, a warehouse or storage complex, secretive cellar, ship cargo ampules, etc. In the third phase, the fumigant is allowable time to totally fill the enclosed galaxy and kill the pest itself (woodborers, termites) or pest plagues (eggs, larvae). Finally, the area is publicized with fresh air and sunlight so that no trace of the biological or gas is left behind. Once this process is finished and thorough inspection is done, the area is specialized 'pest free'.

Chemicals used in fumigation Services:

Until the Montreal Procedure, an international treaty signed in the late 1980s to defend the Ozone layer of the troposphere from depletion, was signed the random use of many chemicals was extensive. The widely used fumigant at the time was Methyl Bromide; its manufacture and use were restricted later.

Methods of fumigation:

Broadly, fumigation techniques can be considered into surface and sub-surface. Surface treatments refer to fumigation done on unprotected surface areas. Sub-surface refers to actions where gases or chemicals have to be functional into spaces like soil, cargo containers and storage tanks etc. Sub-surface fumigation methods are:

  • Plumbing
    • Trenched
    • Short Enquiry
    • Long Probe
    • Mixture
    • Recirculation

The methods accepted for surface fumigation services in Midrand depend greatly on the condition, circumstance and the nature of pest and insecticide. For homes, the 'Tenting Method' is used, where a rubber tent is placed to closure off the area. In larger constructions like entire buildings, other options that take into account the size of the structure and infestation come into play.

Safety:

Fumigation has to be done in an tremendously non-hazardous manner and the action or operator who carries out the procedure has to be a specialized authority with knowledge of the chemicals and how they can be used so as to confirm maximum safety to life and property. The area of information comprises the quantity of fumigant to be used in relative to the area, type of fumigant, time duration for fumigation to take result and complete freshening post-fumigation.

Environmental fumigation measures:

Many pest control and pest service companies place great importance in defining and following environmental pest control and fumigation methods that do not harm or threaten the atmosphere in any way. Newer and progressive practices of pest control follow the Integrated Pest Management (IPM) method that efforts on three normal principles.
