<jats:title>Abstract</jats:title><jats:p><jats:italic>Solenopsis invicta</jats:italic> Buren (Hymenoptera: Formicidae; red imported fire ant) is an invasive species in several parts of the world. A major contributor to the spread of <jats:italic>S. invicta</jats:italic> is infested shipping containers. The vapor of allyl isothiocyanate (AITC), a naturally occurring organosulfur compound, is highly toxic to <jats:italic>S. invicta</jats:italic>; however, AITC is highly volatile. Microencapsulation of AITC in polyethylene (PE) resin slows the release of AITC, making it a potentially useful material for preventing <jats:italic>S. invicta</jats:italic> infestations. Here, we examined the efficacy of AITC microencapsulated in PE (mAITC) as a repellent against <jats:italic>S. invicta</jats:italic> infestation of cardboard boxes, a common containerized cargo. Using baited cardboard boxes, we found that the number of <jats:italic>S. invicta</jats:italic> individuals entering boxes containing an mAITC sheet was significantly less than that entering boxes without an mAITC sheet. When a PE cover, which is often used to protect carboard boxes during shipping, was used, vapor concentrations of AITC inside the boxes were increased and the number of <jats:italic>S. invicta</jats:italic> individuals entering the boxes was reduced almost to zero. These findings indicate that mAITC sheeting, especially in combination with a PE cover, is a promising material for the protection of containerized cardboard-box cargo against <jats:italic>S. invicta</jats:italic> infestation.</jats:p>
