Cardboard, storage
Inspection
Inspection can be challenging due to the number of crevices/corrugations in the cardboard. It may be necessary to remove each item from filled boxes and treat them individually. (Learn more about inspection).
Preferred Control Method
Isolation
If boxes are infested, individual items should be removed, treated appropriately and stored in airtight plastic bags or bins for six months. (Learn more about isolation).
Discard
If items can be stored in airtight plastic bags or bins, cardboard boxes should be discarded in an outdoor trash receptacle.
Other Control Options
Heat
Hair dryer and space heating. Use this technique in combination with the vacuum on the box, but more importantly on the individual items inside the box. Treat cracks and crevices with the heat, then vacuum bed bugs, shed skins and eggs if possible. During space heating boxes should be opened and items loose to ensure good heating. (Learn more about heat).
Not Recommended - Hand wash, Steam, Freeze, Desiccant dust
