Which Types of Pests Controls are Eliminated by Fumigation?

Pests, such as bed bugs, termites, and beetles can affect the harmony and hygiene of a closed structure. To counter the threat, residents opt for fumigation, a powerful and effective control method that involves the use of gaseous chemicals to eliminate a wide range of pests in residential, agricultural, and industrial spaces. The effectiveness of fumigation depends on the type of pests targeted; different pests have varying susceptibility to fumigants.


Insects are one of the easiest targets for fumigation experts: They can infest a wide range of spaces and cause significant damage. Some of the most common insects include:

Stored-Product Insects

These pests infest stored grains, cereals, and other food products. Examples include grain weevils, rice weevils, and flour beetles.

Wood-Boring Insects

Termites, wood-boring beetles, and carpenter ants can cause severe damage to wooden structures. The fumigation process is the most effective way to tackle them.

What is the Difference Between Fumigation and Pest Control?


Fumigation is applied to eliminate bedbugs, notorious for infesting mattresses, upholstery, holes and crevices in closed structures, such as homes and hotels.


Cockroaches are renowned for carrying diseases; these creatures can infest residential and commercial spaces. Fumigation is the best remedy in this regard.

Grain Pests

In agriculture, grain pests (granary weevil, rice moth, etc.) can cause substantial losses. Fumigation is employed to protect grain storage facilities and ensure safety of harvested crops.


Fumigation is used to control rodents, including rats and mice, although it is not the most beneficial method; rodent infestations can be addressed with bait stations, traps, and exclusion methods. However, in cases of severe infestations or in sensitive areas where other methods are impractical, fumigation is a viable option.

Stored-Product Pests

Decontamination is crucial in the agricultural and food processing industries for controlling stored-product pests, such as insects and mites that infest stored grains, legumes, nuts, and dried fruits.


Soil-borne nematodes are microscopic roundworms that can damage plant roots and reduce crop yields. Fumigation can control nematode populations in agricultural fields, allowing for healthier plant growth and crop production.

Microbial Pests

Fumigation can be used to control microbial pests, such as bacteria and fungi. For example, in the healthcare industry, disinfectant gases like ethylene oxide are used to sterilize medical equipment and facilities.

Quarantine Pests

Fumigation is employed at ports and border crossings to control and prevent the spread of quarantine pests that can harm ecosystems, agriculture, and human health. Quarantine fumigation helps ensure a pest-free space (goods and shipping containers) before the delivery enters a new region.

The Science Behind Fumigation

Using toxic gases to exterminate pests within an enclosed space is called fumigation. The chemical can penetrate cracks, crevices, and hidden spaces, clearing the way for a safe and hygienic environment.

Common fumigants include:

Methyl Bromide

Methyl bromide has been labeled as ‘dangerous’ by experts. It can affect the environment adversely. Methyl bromide was once used to control a broad spectrum of pests, including insects, rodents, and nematodes.


Phosphine gas, generated from solid or liquid formulations of aluminum phosphide, is used to fumigate stored grains and structures infested with stored-product pests.

Sulfuryl Fluoride

This odorless and colorless gas is used for structural fumigation to control drywood termites, bedbugs, and other pests in buildings and residences.

Ethylene Oxide

Ethylene oxide is used to sterilize medical equipment and sensitive materials. It can eliminate bacteria and other microorganisms effectively.


This fumigant is used as a warning agent in combination with other fumigants to alert individuals of the presence of toxic gases during the process.

Safety and Regulations

Fumigation is a specialized pest control method that should be conducted by trained and certified professionals. Strict safety protocols and regulations govern the use of fumigants to protect human health and the environment.

Bottom Line

Fumigation is a versatile and effective pest control method that can eliminate a wide range of pests, including insect pests, rodents, stored-product pests, nematodes, microbial pests, and quarantine pests. However, the choice to use fumigation depends on the type of pest infestation, the nature of the environment, and the safety and regulatory considerations. When properly conducted, fumigation can provide long-lasting pest control solutions and help safeguard agricultural crops, structures, and public health.
