Large shipping containers used to hold bulk-packaged commodies, such as hay, can be efficiently fumigated of pests and vermin by means of an apparatus which includes a long, flexible chain or string of gas-permeable, solid fumigant holders, and a long, rigid pole or thrusting member. The holders are joined at predetermined intervals within the string by means of pre-cut lengths of rope or cord and the pole is attached to a distal-most one of the holders and used to thrust the string of holders into the container through its open end and into the headspace above the commodity to be fumigated. The pole is then detached from the string and removed from the container to leave the string in place. The container, is closed, and fumigation is accomplished by permitting the solid fumigant to react with ambient moisture within the container for the static time necessary to produce its toxic gas. After fumigation is complete, the string of holders may be emptied of residue and washed for reuse.
