Fumigation is a method of pest control that completely fills an area with gaseous pesticides—or fumigants—to suffocate or poison the pests within.

It is used to control 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.

This method also affects the structure itself, affecting pests that inhabit the physical structure, such as woodborers and drywood termites.

Pest control is the regulation or management of a species defined as a pest, a member of the animal kingdom that impacts adversely on human activities.

The human response depends on the importance of the damage done, and will range from tolerance, through deterrence and management, to attempts to completely eradicate the pest.

Pest control measures may be performed as part of an integrated pest management strategy.

Industry is the production of goods or related services within an economy.

The major source of revenue of a group or company is the indicator of its relevant industry.

When a large group has multiple sources of revenue generation, it is considered to be working in different industries.

Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and feudal economies.

This came through many successive rapid advances in technology, such as the production of steel and coal.

A machine uses power to apply forces and control movement to perform an intended action.

Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement.

They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems.

The workforce or labour force (labor force in American English; see spelling differences) is the labour pool in employment.

It is generally used to describe those working for a single company or industry, but can also apply to a geographic region like a city, state, or country.

Within a company, its value can be labelled as its "Workforce in Place".

The workforce of a country includes both the employed and the unemployed.

The labour force participation rate, LFPR (or economic activity rate, EAR), is the ratio between the labour force and the overall size of their cohort (national population of the same age range).

The term generally excludes the employers or management, and can imply those involved in manual labour.

It may also mean all those who are available for work.
