Pests and micro-organisms can cause various diseases (digestive and neurological disorders) in homes and offices. To counter their negative effects, owners hire fumigation experts who, with their sophisticated tools, equipment, and chemicals eliminate the entire colony in quick time. Learn about two types of fumigation process. Select the best method for pest elimination. If you are seeking a reliable firm, contact Waterproofing.pk today.
Fumigation is a process in which pests are eradicated from various environments, such as buildings, agricultural fields, and storage facilities. There are three primary types of fumigation methods: structural fumigation, commodity fumigation, and soil fumigation. Each method offers distinctive applications, processes, and considerations, making them essential tools in pest management strategies.
Structural fumigation is employed to eradicate pests in homes, offices, and industrial facilities. In this process, the entire structure is covered with an airtight tent and a fumigant gas is released. This chemical permeates every nook and cranny, including crevices and holes. Sulfuryl fluoride, methyl bromide (although its use is now being phased out due to environmental concerns), and phosphine are common fumigants used in eliminating pests.
The success of structural fumigation depends on numerous factors, such as proper structural sealing, precise chemical formulation and dosage, and careful monitoring. Residents must vacate the premises and follow specific guidelines for re-entry to ensure safety. Proper aeration is also critical post-fumigation to effuse flue gases from the living space.
Commodity fumigation is applied in the agricultural and food industries to protect stored products, such as grains, spices, nuts, and dried fruits from spoilage. Specific fumigants and treatment methods are used to ensure pest eradication without compromising product integrity.
Commodity fumigation is categorized into two types:
During vacuum fumigation, air is removed from the infected area to increase the efficiency of fumigant distribution. Chamber fumigation, on the other hand, involves the use of chambers to apply the fumigant. The latter method is suitable for warehouses and storage facilities where bulk commodities are kept safely. The success of commodity fumigation hinges on aspects, such as proper sealing of the storage area or chamber, accurate dosage, fumigant selection, and adherence to safety regulations.
John Burke, a renowned author, wrote, “Gas fumigation is performed within enclosed chambers or by enclosing a space with a gas-proof covering. Also called space fumigation, this method ensures proper dispersion of toxic fumigants. Gas fumigation is possible in solitary environments.
Liquid fumigation is carried out with sprayers that disperse huge quantities of fumigant across the entire area. This type works faster than solid fumigation. Moreover, it is applied outdoors or in fumigation chamber. Liquid fumigants are toxic to living species, including pets.
Solid fumigation is applied with sprinkling tablets, fumigant pellets, and powder. This method is much safer than the other two types. In addition, it is eco-friendly.
What is the temperature requirement for fumigation?
The temperature range for fumigation is 10 to 35oC. With increase in every degree, the concentration of the fumigant required to eliminate insects decrease. On the contrary, fumigants vaporize and diffuse more slowly in cold conditions.
Fumigation is a beneficial pest-control process. The two main types of fumigation—structural and commodity address pest control challenges, ranging from eliminating hidden insects in buildings to safeguarding stored products. Proper execution of each method involves precise dosages, complete sealing of structure, and more. As part of integrated pest management strategies, fumigation plays a crucial role in maintaining the health and productivity of environments where pests can pose significant threats.
