Look out for anything starchy like flour, some grains or also sesame. I keep all those things in an airtight container (in their original boxes) and only get them out when i need them.

Best is to move everything out of the shelves, check every box and deep clean the shelf as well. I also found larvae in the holes for the adjustable shelves of the cabinet too.

I bought a container for dried dog food, which has seals and also a lid if you want to pour it. I rather scoop it out after removing the whole lid though.
