Fumigation is a method of pest control that completely fills an area with gaseous pesticides to suffocate or poison the pests within. It is utilized for control of 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. Structural fumigating techniques differ from building to building, but in houses a rubber tent is often placed over the entire house while the pesticides are being released into the residence.
This concentrates the gases and prevents them from escaping and doing harm to people in the neighbourhood. During this time the residents of the house must find an alternate residence for up to a week depending on the fumigant used, which in turn depend on the severity of infestation and size of the house.
Methyl bromide was among the most widely used fumigants until its production and use was restricted by the Montreal Protocol due to its role in ozone depletion.
Widely used fumigants include:
- Methyl Isocyanate
- Hydrogen Cyanide
- Sulfuryl Fluoride
Fumigation is a hazardous operation, and generally it is a legal requirement that the operator carrying out the fumigation operation holds official certification to perform the fumigation. Fumigation usually involves the following phases. First the area to be fumigated is usually covered to create a sealed environment; next the fumigant is released into the space to be fumigated; 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.
The correct ventilation of the area is a critical safety aspect of fumigation. It is important to distinguish between the pack or source of the fumigant gas and the environment which has been fumigated. While the fumigant pack may be safe and spent, the space will still hold the fumigant gas until it has been ventilated.
Hazard Analysis and Critical Control Points (HACCP) is a systematic preventative approach to food safety and pharmaceutical safety that addresses physical, chemical, and biological hazards as a means of prevention rather than finished product inspection...Read More

The Public Health (Ships) (Amendment) (England) Regulations 2007 came into force on 15th June 2007. These regulations implement the requirement of the International Health Regulations 2005 and as a result, the former Deratting Certificate have been replaced by Ship Sanitation Control Exemption Certificate/Ship Sanitation Control Certificate.
The new certificate will involve a more detailed inspection, which will include checks for vectors of illness and controls in place to minimise the risk of the spread of any illness. If the inspection reveals no evidence of a risk to public health, a Ship Sanitation Control Exemption Certificate will be issued which will be valid for 6 months.
Should evidence of infection or contamination be found, including: vectors in all stages of growth; animal reservoirs for vectors; rodents or other species that could carry human disease, microbiological, chemical and other risks to human health; signs of inadequate sanitary measures. A Ship Sanitation Control Certificate will be issued outlining the vector or reservoir and treatment undertaken.
Before staff can inspect a vessel for the purpose of undertaking a Ship Sanitation inspection the following information should either be emailed or faxed.
- Port where the vessel will be inspected
- Name of ship
- Flag or state registered
- Registration/IMO number
- Gross tonnage
- The last set of microbiological water results must also be forwarded before an inspection can commence.
We can take and submit drinking water/ice/swimming pool water samples for bacteriological examination on request. There will generally be a small charge for this service and a laboratory report will be provided together with a certificate.
Requests for inspection should be made to Pestman Pest Management Services by e-mail to firstname.lastname@example.org
