Do ants have a sense of smell?
Yes they have one of the best sense of smell in the animal kingdom.
Bears have an incredible sense of smell. Even when a car is closed, they may smell the foam inside the car seats, which has the same smell as an ant colony. Ants and ant larvae are food for bears, so bears will tear up the car and its seats in search of the ants it thinks it smells. Leaving food in your car can also attract them, because they can smell the food.
