Depending on the type of ants you’re dealing with, you may add honey, jam, peanut butter, or another treat to make the trap more appealing. Note that you must use confectioners sugar - ants will be able to separate regular sugar from the baking soda.

How Do Ants Detect Sugar?Īnts, like other insects, use chemosense to detect sugar and other food. Some ants can store many memories and activate the correct ones as needed. The ants use different landmark memories on their way to and from the food site. On later trips back to the same food source, carpenter ants use landmarks and memories of the whole landscape to find their way. On this first trip, the carpenter ant stores images of the route. This method of traveling is slow, since the ant has to walk with his antennae to the ground to pick up the pheromone smell. On its first trip to a food source, a carpenter ant follows the pheromone trail established by other ants. When other worker ants come across the pheromone trail, they may abandon their own random search for food to follow the pheromone trail directly to the food source.Ĭarpenter ants, which are sometimes called “wood ants,” on the other hand, use a combination of pheromones and visual memories to find their food. While it travels home, it lays down more pheromone on the trail, reinforcing the trail. After an ant finds food, it turns around and follows a different pheromone trail back to the nest. When worker ants leave their nest to search for food, they leave behind a trail of pheromones (chemical scents) - like leaving a trail of breadcrumbs to help you find your way home. You may see them near your dishwasher, sinks, bathtubs or other damp areas. When ants are active in the winter, they typically forage at night looking for food and moisture. Worker ants often forage for food at night (between sunset and midnight) in the spring and summer, traveling up to 100 yards from their nest to find food.Īnts sometimes remain active in the winter if their nest is warm enough from sunlight, mild outdoor temperatures or inside heat. Worker ants (sterile, wingless females) generally find food for the queens (who lay the eggs), reproductive males and young in their colony. Indoors, carpenter ants feast on meat, pet food, syrup, honey, sugar, jelly and other sweets. Outdoors, carpenter ants feed on live and dead insects and honeydew, a sweet liquid produced by aphids and scale insects. For example, carpenter ants prefer meats and foods containing fats and sugar. It’s this exceptional sense of smell that helps ants find food.Īnts eat a variety of foods, depending on their type.


Did you know that ants have a keen sense of smell? Ants actually have four to five times more odor receptors (located on their antennae) than most other insects.
