We have an ant problem in our kitchen and one more than one occasion the ants have found their way into our boxes of cereals. We were using the Sistema ones (with the blue clips). These ants are teeny and unstoppable. I've had to throw away a heap of sugar because they found their way through the thread of a glass jar.
My question is, are Tupperware containers (the Modular Mates) sealed tightly enough to stop ants? Has anyone had an issues with ants or other insects getting into tuperware containers?
