fumigate

To fumigate means to treat a place, object, or shipment with gas, smoke, or vapor in order to kill pests or harmful organisms. It usually refers to filling an enclosed space, such as a building, room, tented house, container, or cargo hold, so the treatment can spread everywhere. The word comes from the Latin fumus, meaning "smoke," which points to its history in smoke-based treatment.

In the past, people often relied on smoke from burning materials. Today, fumigation usually involves special chemicals released as gas or vapor. Because these substances can be dangerous, the process has to be handled with great care. It is not something you do casually.

Fumigation is common in agriculture and shipping, where it helps protect stored grain, fruit, wood, and cargo from insects and other pests. It is also used in buildings - think of a house covered with a tent so termites can be wiped out. In some historical settings, fumigation was also used as part of disease-control efforts, especially around ships and goods arriving at port.

Today, other pest-control methods are often tried first, but fumigation remains an important option when an infestation is widespread or hard to reach. So, if you hear that something has been fumigated, picture a sealed space filled with a strong treatment that reaches deep into cracks, surfaces, and stored goods to drive out or kill the unwanted invaders.
