Fumigation is a method of pest control that completely fills an area with gaseous pesticides—or fumigants—to suffocate or poison the pests within. It is used to control pests in buildings (structural fumigation), soil, grain, and produce, and is also used during processing of goods to be imported or exported to prevent transfer of exotic organisms. This method also affects the structure itself, affecting pests that inhabit the physical structure, such as woodborers , drywood termites and Seeds.
Fumigants are toxic to humans as well as to insects. The claim may occasionally be made by unqualified or irresponsible persons that a certain fumigant is poisonous to insects but harmless to humans. From their very nature as volatile, penetrating and toxic chemicals, all materials used as fumigants can, if not used with proper precautions, poison human beings. Any exposure before, during or after a fumigation treatment can be harmful; hence anyone using fumigants should have some knowledge of their toxic properties and should take every precaution to avoid exposure to them. Nevertheless, if proper care is taken, the work is no more hazardous than any other industrial or domestic technique that uses potentially harmful chemicals.
Therefore, we are keen in our company to get employees to the latest Fumigation systems and continuous training on this field and the best pesticides with compliance with international safety instructions and International Standards For Phytosanitary Measures No. 15 (ISPM 15)
Fumigation generally involves the following phases:
First the area intended to be fumigated is usually covered to create a sealed environment.
Structural fumigation techniques differ from building to building, but in houses a rubber (usually the tent is made of plastic\pvc coated canvas material) tent(s) are often placed over the entire house while the pesticides are being released into the vacant residence. This process is called tent fumigation or "tenting". The sealed tent concentrates the poisonous gases and prevents them from escaping into the neighborhood. The process can take up to a week depending on the fumigant used, which is in turn dependent on the temperature and the kind and number of pests.
next the fumigant is released into the space to be fumigated. In precise quantities according to the size of the product to and the quantity and type of pests. then, the space is held for a set period while the fumigant gas percolates through the space and acts on and kills any infestation in the product
next the space is ventilated so that the poisonous gases are allowed to escape from the space, and render it safe for humans to enter.
If successful, the fumigated area is now safe and pest free.
This stage is very important because people need to know how long after fumigation is safe. After dismantling fumigation tents and aerating the house, In Al Raha Developing we use clearance device to test the level of dissipation of the fumigant. Clearance devices are electronic devices which are calibrated to measure toxicity dissipation levels of fumigants.
What are the chemical used for fumigation?
The Most Common Chemicals Used in Fumigation. Magnesium Phosphide: This solid can be converted into powder or granules. The phosphine gas it produces when introduced to acid or moisture is very toxic. Methyl Bromide: Methyl bromide, commonly used in farming, can be a fumigant as well as a solid.
Why fumigation is required?

How long does it take to fumigate a house for bed bugs? A thorough insecticide treatment should involve 2-3 visits from the PMP, as it is unlikely all the bed bugs will be killed in the initial treatment. An insecticide treatment typically takes about 30 minutes to 2 hours per room depending on size and condition of the room.
What is fumigation in agriculture?
Fumigants. Fumigation is a pest control method in which a pesticide gas or vapor is released into the air or injected into the soil to kill or eliminate pests. ... Soilfumigation is a commonly used agricultural practice to treat fields to reduce weeds, nematodes and other soil insects and small rodents such as moles.Oct 26, 2016 What does ISPM 15 mean? International Standards For Phytosanitary Measures No. 15 (ISPM 15) is an International Phytosanitary Measure developed by the International Plant Protection Convention (IPPC) that directly addresses the need to treat wood materials of a thickness greater than 6mm, used to ship products between countries.
Are CHEP pallets heat treated?
ISPM 15 requires that pallets be either chemically fumigated or heat treated to prevent the spread of wood and plant pests. ... These are Heat Treatment (HT) to a minimum core temperature of 56°C/132.8°F for a minimum of 30 minutes, and fumigation, using Methyl Bromide (MB) to the prescribed dosage and temperature.
