i have had infestation after infestation and no matter what i did they alwasy came back. I removed everything from the pantry, threw out all the infested stuff and wiped down all the shelves, walls, under shelves and wiped down each jar and packet..whew what a job....I was sick of it...and then i read that bay leaves stop the reproduction cycle so i went out into my garden ( i have 3 bay leaf trees) and took 20cm cuttings and put them at the back of the pantry close to all the things that they always infest. i can happily say i have been bug free now for 6 months....I also used those sticky traps previously and they were full of moths so as you see i had a huge problem and the person who said that she thinks we bring them home from the store might be right.
