Where do insects live and can I clean up to keep them away from my storage? A Insects typically like warm dark area’s with a source of food. Common places to find insects are in leftover bags of grain, under hoppers, in machinery where grain gets caught and under rubbish around storages. Cleaning grain storages, surrounding areas and grain handling machinery is the first line of defence against insects.
