Fumigation: what it is, how, what and by whom it is carried out and why it is needed

Fumigation, what is it for manufacturing plants? At such facilities, these procedures are mandatory. Carrying out this operation is a necessary step for such premises as bakeries, elevators, warehouses, cattle yards, etc. It is also worth adding that such a procedure is necessary without fail and where it is planned to store antiques or just for a long time. save any things. Such premises often include libraries, book archives and so on.

What is fumigation? This is a procedure whose purpose is not just to neutralize harmful insects. It is necessary to carry out all the work as soon as possible, and also to keep the products in their initial state. That is, color, taste, smell and other components should not be changed.

Who does all the work?

This issue is worth special attention. The reason for this is that the whole procedure is associated with a great risk that arises from the fact that the work itself is carried out in the premises where expensive food or non-food products are stored. In addition, all procedures must be carried out quickly and efficiently so that the people around are not injured and there is no danger to the health of the staff. For these reasons, this job is trusted only to professional workers. What is fumigation? This is not only an effective and fast method of getting rid of pests, but also a job that can be trusted only to highly skilled individuals.

If employees know their business, you can get the following benefits:

  • Responsible company always gives a guarantee on their work.
  • Processing will be carried out quickly, efficiently, and most importantly, the effect will last for quite a long time.
  • The procedure should ensure the safety of products and materials undergoing treatment, and the possibility of harming human health should be excluded.


Upon arrival, specialists will evaluate several criteria. Among them, we can single out the scale of infection with insects, the territory of the premises, the object of disinfection, and many others. Depending on these criteria, the degree of sealing will be determined, and the method of work will be selected.

The first method of fumigating a room is sounding, which is considered an economical way of dealing with insects. Most often, the method is used in cases where it is necessary to carry out decontamination of warehouses with cereals that are fully loaded with raw materials. Fumigation of grain with tablets occurs in this way: first they are placed over the entire area of ​​the warehouse, and then, using a probe, they are processed evenly. It is worth adding that mixing with the products does not occur, since the tablets are stored in special bags.

Types of jobs

It is important to know that the fumigation process changes depending on which object is to be disinfected.

For example, fumigation of grain is carried out directly at the place of its storage. This procedure is necessary to get rid of larvae, pupae, adult insects. The drug, which is used, "Phosphine", is introduced into the space and closed indoors for 7 days. Before that, the pre-grain is covered with a special film. For human health, couples are safe, and they are not absorbed by raw materials.

Fumigation of warehouses is necessary in order to disinfect the objects where grain will be stored in the future. Before you start work, you must remove all objects that are not subject to fumigation, as well as carry out the sealing of the object. In the course of work, not only adult insects will be eliminated, but also their larvae, eggs, and also small rodents. The duration of the procedure is 4 days.

Fumigation wooden house

What is wood fumigation for? The primary task is to get rid of wood-boring insects and their larvae. In addition, the same procedure is prophylactic, preventing the occurrence of such pests in the future. When conducting this procedure, a substance is used which is characterized by subsequent degassing. By this is meant the process by which all substances harmful to human health decompose at the molecular level. Most of these logs in the future are building houses and other important structures.

From the advantages of this operation for the processing of any raw materials, the following can be highlighted:

  • High efficiency, which consists in the destruction of any insects and their larvae, eggs, etc.
  • Universality of this method. It can be used for processing both food and non-food items.
  • The method is considered completely safe.
  • Efficiency.
  • The procedure eliminates not only existing pests, but also prevents their further occurrence.

This gas is most common during fumigation. It is poisonous, colorless, and also has the smell of rotten fish. For example, fumigation of a wooden house with such a preparation is as follows:

  1. The fumigant is either spread in the air inside the desired room, or only necessary surfaces are treated with it.
  2. Depending on how large the pest infestation is, the treated room or the object is kept inside the hermetic space for several days.
  3. Next, carry out the degassing process.
  4. The last stage is the determination of the degree of degassing, if it is satisfactory, then the work ends.

The peculiarity of "Phosphine" is that, when it appears on a ventilated space, it disappears very quickly, leaving no traces behind it. For the same reason, it is very important to seal the workspace.

How is fumigation different from other species?

The main difference of this method from others lies precisely in the fumigant. Since the gaseous substance is used, it actually falls into any gap. In addition, any surface or material that is indoors is treated. The chemical substance in the gaseous state penetrates the material to a great depth, which guarantees 100% elimination of any pests.

In addition, a distinctive feature was the fact that the object of fumigation can be a large number of various objects. These can be agro-industrial complexes, vehicles, customs warehouses located at border points. In addition to fumigation with "Phosphine", a method such as aerosol generation and aerosol gas disinfection of fogging is also used.

What is fumigation?

Fumigation will help protect food supplies, protect your business and not lose your reputation - combating barn pests and other flying insects. Fumigation is one of the most effective and inexpensive methods of disinfecting food and non-food products from insect pests.

Thus, the preparations can have a deep impact on the object being processed, and this in turn guarantees a 100% result.

Processing chemicals

Methyl bromide - chemically pure methyl bromide is an odorless and colorless gas. The gaseous substance is almost 3 times heavier than air, which allows it to penetrate into the cargo. Liquid substance is a good solvent for varnishes, oils, fats, paintwork, therefore, when working with this methyl it is impossible that it contacts with the above listed materials.

Methyl bromide is very toxic to all mites and insects. They are disinfected with fodder and food grains, grain products, fodder raw materials and oilseeds, beans, peas, cocoa beans, nuts, coffee, raisins, figs, ginger, dates, etc. Sugar and tea can be disinfected only if harmful quarantine is detected pests.

Fumigation with phosphine-based preparations - aluminum and magnesium phosphides. The main active ingredient is phosphine. Substances capable of spontaneous combustion, if they are in contact with a drip-liquid moisture.

Does not destroy wood, tin, galvanized tin, steel, burlap, tarpaulin, but causes oxidation of copper objects. Therefore, it is impossible to handle the premises where there is equipment, computers, technological equipment.

Phosphine-based preparations are treated with dry cargo products. Planting material, developing plants, vegetables and fruits are not processed. Phosphine does not settle on products, but is easily degassed.

Fumigation process

The process of aeration or fumigation is carried out with the help of special equipment and machinery, a fumigator machine, which is charged with an active insecticide affecting pests. The most commonly used is any special professional preparation based on phosphine. The overall scope of fumigation works consists of the following tasks:

  • aerosol-gas attack of warehouses, storages,
  • fumigation of grain in motion on a conveyor belt,
  • disinfection by fumigator of elevators, mills, bakeries or shops of processing of grain,
  • treatment by the generator of dispersion-condensed fog with gas of a loaded or empty warehouse, storage.

Usually, the processing time for a new technology is from 2 to 7 days, depending on the area of ​​the room to be disinfected.

Where spend

Fumigation is used for the purpose of disinfecting and getting rid of insects in many industrial facilities, in gardens, during harvesting, for the purpose of its most long-term preservation, as well as in the room where such a need arises.

This manipulation can be performed practically in any place and under any conditions, however, it requires certain skills and protection of the person who conducts it.

The simplest and most well-known - but, alas, not always an efficient way - is the treatment of premises with the help of gas cartridges (for example, Dichlorvos) containing highly volatile liquid.

Practically all export and import products are also subjected to this procedure, and sometimes even food.

Who conducts

To perform this procedure, you can hire a specially trained team of specialists who will perform everything qualitatively and in a short time, however, it must be remembered that for some time it will not be possible to enter the room that has been fumigated.

You can not also eat and processed foods.and contact with the processed materials immediately after the procedure.

If you have all the necessary chemical protection, as well as materials necessary for manipulation, you can do it yourself. It is only necessary to remember that it is imperative to carefully monitor personal safety and thoroughly wash hands and face immediately after the procedure is completed.

The process itself may vary depending on what kind of substance it is performed, for what purposes, against which pests and which materials should be processed.

In order not to separately describe each of the many possible combinations, we describe the procedure for fumigating a room using one of the most popular fumigants, phosphine:

  1. First, it is necessary to remove from the premises all items and products that could potentially be damaged during this procedure.
  2. Then a special cap is put on the room, an awning (if there is such an opportunity), which would prevent the release of active substances.
  3. The fumigant is introduced into the room, based on their previously calculated dosages.
  4. After that, the room is kept in a sealed state, without circulation of air masses, for 3-7 days, depending on which specific pathogen or pest should be destroyed during the procedure.
  5. This is followed by degassing (weathering of the fumigant), which, according to the regulations, should last no less than 2 days.
  6. At the end, the completeness of degassing is measured using indicators, and in case of a satisfactory result, the room can be put back into operation.

Fumigation method

Modern companies offer several different methods of this process. The most popular and most commonly used in relation to various food products (nuts, tea, grains, etc.) is the surface method.

It involves the scattering, indentation or rubbing of the fumigant in tablets or granules throughout the treated area. There are, however, some more techniques that should be given attention.


There are two types of this method: short and deep sounding. As the name implies, they differ primarily in the depth of the product (most often it concerns grains) that the fumigant will be located.

Most often, a combination of these sensing techniques is used, since it is this that allows us to achieve the most stable and adequate results.

The methodology of this type of fumigation is that using a special probe (a long metal stick with a fumigant carrier at the end), a predetermined amount of fumigant is introduced into the product (most often grains), which negatively affects all pathogens, thereby extending the life of the product.

Typically, a single portion of the fumigant is not enough for adequate protection and prevention of disease in all the required number of products, so the process is repeated the required number of times.

Gassing or fumigation

This technique is more widespread because of its versatility. With its help, you can handle premises, gardens, food, building materials (including wood) and many other items.

A significant disadvantage of this method of processing is its great danger to humans compared with the surface method and the method of sensing.

The fumigant is placed in a special apparatus, which brings it to a gaseous or vaporous state, which largely depends on what kind of chemical structure is inherent in the substance in normal conditions of its storage.

Next, the gas or vapor is uniformly applied to the desired surface or materials, after which it is left for a certain period of time in sealed conditions.

Methyl bromide

This organic substance without a pronounced odor dissolves very well in water at a temperature of 17 ° C. This substance is very toxic to the nervous system of any organisms, and can very quickly lead to paralysis of both insects and warm-blooded organisms if they inhale too high a concentration (over 1 mg / m3).

This fumigant is widely used for the treatment of various crops (nuts, dry fruits, grains, etc.), as well as for the processing of used clothing. Sometimes it is also used to prevent the occurrence of various bacterial and insectoid invasions in storage facilities.

The drug is distributed in liquid form in hermetic containers (“Metabrom-RFO”).

Types of fumigation treatment

In general, the processing of different objects using fumigation is not very different. However, there is its own, slightly different specificity.

As already mentioned, the grain is predominantly processed using a combination of short and deep sensing. In this case, the probe with tablets or granules of the drug is injected at the required depth according to the protocol and left them there, taking out the probe in order to lay the next batch of fumigant at the calculated distance.

Most often the premises are treated with aeration - this method allows to achieve the most adequate and long-lasting results, while the cost of such a procedure will be much less than with a zonal or surface treatment method.

A prerequisite for successful treatment of premises is their sealing before the introduction of gases. Be sure to also remember the need for degassing, which is designed to save your health.

Soil fumigation is most often carried out using the surface method. The substance is scattered at a certain distance from each other in the form of capsules, tablets or granules.

This type of tillage can significantly increase the yield of your beds, while not doing absolutely no harm to plants, since most fumigants are not phytotoxic.

The peculiarity of wood is that it can be subjected to this procedure in any form convenient for the owner - it all depends on where it is at the time of processing.

If the wood is in the room, it is recommended to carry out gassing, and if in the open air or at the stage of transportation, it is better to use the surface method.

Tara is best treated with aeration from the inside. At the same time, after a sufficient amount of fumigant is injected into it (it is calculated based on the initial volume of the container and the activity of a particular substance), the container must be tightly and tightly closed.

Reuse of the container after fumigation is possible only after careful degassing.

Frequency of work

It is impossible to establish any permanent schedule for this procedure, since it is often carried out according to strict indications and regulations, which differ in different enterprises and warehouses.

Sometimes fumigation is prescribed due to the fact that a special sanitary-epidemic body reveals a violation in the form of the presence of a particular disease-causing form or an insect in a room or product.

In general, for prophylactic purposes, in the absence of any “acute” indications for the procedure — clearly visible signs of the appearance of insects or diseases — as well as in the absence of any instructions from government supervisors, this procedure is recommended to be carried out no more frequently than once every six months.

Warehouse fumigation

Fumigation of warehouses is understood as a method of disinfecting rooms and free tanks in which pesticides are sprayed in a gaseous state. Fumigation subject: feed mills, mills and factories, warehouses for various purposes. Fumigation is the most effective method of decontamination of warehouses and industrial premises. Processing tactics depend on the area and the stored goods.

Fumigation provides an opportunity to rid warehouses of various pests, including pathogens, preventing their subsequent occurrence. The procedure ensures the safety and duration of storage of goods and products in warehouses.

General information

Fumigation is a pest control, aimed at the destruction of a wide group of pests and plant pathogens. A similar procedure is done by two methods: gas and fumigation. The first method differs from other types of processing in that chemicals not only spread in space, but also penetrate objects, materials, etc. It is the aeration that gives a 100% result in pest control.

Fumigation is carried out using special devices - fumigators. They allow you to quickly distribute gas and toxic fumes, covering a large area. Pesticides are used as damaging substances. The most effective of them are:

  • phosphine,
  • chloropicrin,
  • methyl bromide,
  • dichloroethane and others.

Phosphine is used for the treatment of pests of grain, warehouses, grain processing enterprises and tar. While methyl bromide is used in quarantine and prophylactic purposes.


What is fumigation for, and where can I use this disinsection method? The procedure is used to disinfect many foods and various raw materials: grains, vegetables, cereals, tobacco leaves, fruits. Wood, wool products, furniture, books (in archival rooms or libraries) are also attached to gas and fumigation.

Most often, our specialists receive orders for processing such objects:

  • warehouses, warehouses filled with raw materials and food,
  • cars and holds filled with grain for further transportation,
  • production and utility rooms,
  • bakeries, mills, flour mills, grain elevators and cereal shops.

Why exactly these objects need processing? Because they are intended for storage, processing and transportation of raw materials that may be infected with pests and pathogens of plant diseases.

Pesticide fumigation helps eliminate:

With full compliance with the technology of fumigation is absolutely safe for people and warm-blooded animals. Moreover, it guarantees a 100% result in the destruction of pests.

Key methods

How do fumigation specialists perform disinsection? For a similar procedure is used:

  1. Method GAP. Provides for the generation of pesticide aerosol. Such fumigation is characterized by universality, since it allows the elimination of all currently known pests.
  2. AGD method. This is an aerosol-gas disinsection, in which a “fog” generator is used. The procedure is effective, since chemicals penetrate into hard-to-reach places, crevices, etc.
  3. Sounding. The method is used to process cereals with fumigated tablets. Probing is a procedure with less efficiency. Why do they spend it? Because of the efficiency of the method.

Due to the qualifications of our specialists, as well as good equipment, we carry out the processing of premises and raw materials using any of these technologies. When disinfecting, we take into account all the norms and restrictions of the legislation; therefore, the procedure is distinguished by safety, efficiency and speed.

Features of

The control of plant pests and pathogens is a complex process. To achieve maximum results, it is important to go through all the stages of disinfection. Without special chemicals and equipment this cannot be done. Therefore, the work should be trusted by qualified professionals.

The key stages of fumigation include:

  1. Evaluation of the level of infection. Specialists of our company initially determine the extent of damage to the object by malicious insects.
  2. Sealing the room. At this stage, isolation of all doors, windows, slots is carried out to increase the efficiency of the procedure.
  3. Dosage calculation. Experts prepare a solution, the concentration of which meets the legal standards.
  4. Spraying. This is direct fumigation or aeration, during which chemically active substances are distributed throughout the room.
  5. Degassing. After completing all procedures, the room is ventilated for 4 hours or more.

Many customers have concerns that such disinfection may adversely affect the properties and taste of raw materials. Our experts comply with the requirements for fumigants, so the preparations do not distort the smell, color, appearance of the processed products. Moreover, after disinfection there is no need for cleaning, as the chemicals leave no sediment.

Processing frequency

Legislative norms clearly established how often fumigation should be carried out. For objects with an increased risk of infection (warehouses, flour mills, mills, etc.) it is recommended to process the premises at least once a year. At the same time it is important to comply with sanitary standards for the storage, transportation and processing of raw materials. Otherwise, even more frequent disinfection will not insure against the appearance of pests.

Rules of the company

Conducting fumigation of raw materials, premises, products, our specialists draw up an act of procedure. It is prescribed the following data:

  • name of the infected object
  • territorial location,
  • infection rate
  • types of insects found
  • procedure parameters (number of chemicals, drug labeling, MPC standards, processing technology),
  • disinfection results.

This act is a guarantee of our customers to receive quality services. To order it, it is recommended to contact managers.
