Grain Fumigation Silos & Stores

At Fumigill, we are proud to offer a range of grain fumigation treatments to customers throughout the North West region and across the UK. Our team is highly trained in fumigation services to eradicate pest species and provide pre-harvest grain store cleaning and treatments to help reduce the risk of an infestation once the commodity is stored.

What is the grain fumigation process?

The process of grain fumigation begins by creating a sealed, airtight space in which the grain stores can be safely fumigated. Once the area is secured, our team will start fumigating using phosphine to eradicate all living pests. The fumigant will be maintained at a certain concentration for a set time to ensure insects and mites at any stage of their life cycle are dealt with.

After enough time, the fumigant will be removed, and the space will be monitored until levels are reduced to below the safe WEL (workplace exposure limits). Once our team is confident the area is safe, you will be issued a gas-free clearance and treatment certificate.

Fumigation of grain stores and silos leaves no toxic residue, and our team will always ensure that all personnel and products are kept safe throughout the process.

In total, grain fumigation will take an average of 14 days when accounting for the exposure time, ventilation and withholding period. As such, we advise all of our customers to regularly monitor their product to allow sufficient time for fumigation if required.

Why is grain fumigation important?

Grain is typically stored in thousand of tonnes in one space for prolonged periods, and if adequate storage conditions are not maintained, i.e. temperature and humidity, a small number of insects can quickly multiply to many hundreds of thousands.

Ultimately, this can have a major impact on the quality, weight, and value of the grain, affecting your business financially and the sector as a whole.

Once an insect infestation reaches high levels in these storage areas, the only real option for control is through effective fumigation.

What chemical is used for grain fumigation?

Grain fumigation in the UK involves using Metallic Phosphides to produce a fumigant gas within an airtight space. These gases are maintained for a set period of time to penetrate deep inside the commodity and eradicate pests at any stage of the lifecycle.

There are many species of stored product insects and mites commonly found in stored grain, such as the Saw-toothed grain beetle and the Rust-red grain beetle. Whatever pest species you suspect has infested your product, our Fumigill team can deal with it quickly and efficiently.

Common signs of an infestation

There are several signs to look out for when monitoring grain stores for an infestation. Some of the most common are:

  • Evidence of damage to raw materials and foodstuffs
  • Increased grain temperature that can lead to dampness and mould
  • Musty/sweet grain odour
  • Visible exit holes in grains
  • Grain discolouration
  • Dense webbing from insects on grain or equipment
  • Insect tracks through a floury dust
