Researchers have found that caffeine sharpens an ant's mind - at least when it comes to locating food.
Ants feeding on food containing caffeine learned the location of the food far quicker than the location of food without caffeine, making the foraging process more efficient. Ants demonstrated a reduction in foraging time to food containing caffeine by up to 80%. This was not due to walking faster but rather shortening the distance to the food.
The researchers believe caffeine has potential for boosting the performance of ant baits.
Caffeine doesn’t just perk up humans—it can sharpen ants’ minds too. Invasive Argentine ants given caffeinated sugar learned to find food much more efficiently, taking straighter paths and reducing travel time by up to 38%. They weren’t faster, just more focused, indicating improved learning...
