You hit the pantry for some cereal, open the brand new box and somehow find ants inside. Breakfast ruined. Has this ever happened to you? Even though that brand new box of cereal is sealed tight and on the top shelf of your pantry, it could very well be full of ants, thanks to their strong and sharp front mandibles. These little claws, which you may call "pinchers," is the key to ants getting into new food. The fact that your pantry doesn't have the inhospitable climate of your fridge, means it's prime ground for an infestation.
