Stinky, smelly, warm discarded food may sound disgusting to you, but it's heaven on Earth for a trail of ants. Nowhere else in your house, not even your fridge or pantry, will be more susceptible to an ant invasion than in and around your trash. Tiny hairs on the ants' antennae have thousands of cells that allow them to seek out the really smelly stuff. That makes your trash the top target in your home. Trashcans are also on the floor, giving ants easy access to the good stuff. You can help the situation by putting actual food waste into a bag and in the bin outside.
