They have ants in every room, in their cabinets, in their food. Ants literally crawl onto their plates at dinner! But they keep saying "We're just going to try to get rid of them our own way" which basically involves smashing a few now and then. I have even offered to pay for the extermination (though they can easily afford it) and they still refuse. I am at a total loss as to why they are choosing to live like this and they have no explanation. Please help!
