What is fumigation?

Fumigation is an officially approved procedure for the destruction, removal or conversion of pests into infertile (FAO, 1990; revised FAO, 1995). This is a dangerous procedure that poses a serious risk to human health – fumigants are highly toxic compounds, and their excessive exposure to humans can lead to death. That is why fumigation should be performed only by a licensed fumigator.

During fumigation, toxic gas is introduced into the container at a sufficiently high concentration, so that all pests die. Such a method shall be used when pests in products cannot be achieved by conventional control methods.

What is a fumigant?

Fumigant – is a highly toxic chemical that turns into gas at the right temperature and humidity and becomes the cause of death for pests.

Fumigation of cereals or wood

Fumigation of cereals is aimed at controlling pest infestation can be used in two ways: prophylactic, when destruction is carried out in the usual way, usually shortly after landing at the place of storage, even if insects or ticks are not found under review; or tactically, fumigated at the first signs of contamination.

Wood fumigation is most often carried out on round and sawn wood. Although, according to the studies carried out, insects do not store in wood containing more than 12 percent of moisture and wood, which was dried at a high temperatures of 170-180 C, the delivery of wood into some countries without a certificate of fumigation will fail.

In most cases, second fumigation is not required if good hygiene and proper room sealing have been observed, since after proper completion of first fumigation procedures, fumigants are able to completely destroy all insects. If insects appear after fumigation, it is most likely that either fumigation was not performed properly or the amount of gas was not high enough. Fumigation works properly only if a sufficient concentration of gas can be maintained for an appropriate period of time.

Use of fumigants

Currently, aluminum and magnesium phosphine are the only grain fumigants widely used for grain fumigation. However, sulfuryl fluoride and ethyl formate have become available in some countries of the world over the last 10 years. Previously, the popular fumigant methyl bromide is no longer used because after the Montreal protocol it is banned worldwide.

Suggested solutions

JSC ONZE offers cargo fumigation service for your cargo on board, marine container, wagon or cargo storage site. After the fumigation, we ventilate the place of fumigation, the vehicle or the marine container. We’re going to issue a fumigation certificate, which will be also a confirmation that we’ve done the job perfectly.

We recommend you order cargo fumigation together with land transport,sea freight or stevedoring services. With full information about loading dates, departure and arrival times, we will be able to better arrange the entire logistics circuit by inserting the cargo fumigation into the process.
