The khapra beetle, considered the world's most destructive insect, has popped up in DFW luggage screens on five different occasions in recent months. In each instance, the beetle has been found in dried food a passenger was attempting to get past customs, despite not declaring the packages of rice, dried beans, coriander seeds or fava beans on customs forms. The packaged food originated in India and Sudan.

Since 2013, U.S. Customs says it has intercepted Khapra beetles from passenger luggage more than 70 times. If it gets into the food supply, not only does it eat the grain, the beetle can also ruin the viability of seeds.
Each of the bugs, and its host material, was destroyed after interception.
