The fumigation of wooden crates involves the use of fumigants, a type of compound, to kill pests, pathogens, or other harmful organisms in sealed spaces. Fumigation of wooden crates is commonly carried out in two methods: chemical treatment and heat treatment.

Fumigation wood box agents are chemicals that, under specified temperatures and pressures, can produce gas concentrations lethal to harmful organisms. This molecular gas can permeate the materials within the fumigated wood boxes, and after the fumigation process, the ventilation and air dispersion are very easy.
