Black ant nests can be large and typically contain between 4000 and 6000 ants. The colony has a single queen that can live up to 15 years. During July and August, new queens will be produced and will then to start their own colony. They’re particularly attracted to sweet foods and they don’t sting. One successful ant will be able to communicate information to their co-workers using pheromone trails, leading to huge numbers of worker ants invading and contaminating human foods.
