It is important to identify ants correctly before trying to control them. They have different habitats and the control measures are different. Do they live outside or inside? Keeping counters clean of spills, breadcrumbs and leftover food is already a start to minimize intrusion by those pesky ants. Ants have the largest brains of any insect. One ant has 250,000 brain cells. Humans have 50 to 100 billion brain cells. Worker ants live for between 45 and 60 days on average. Queen ants live for about 30 years! Workers spend the first few days of their lives caring for the Queen and any babies. They then dig and work around the nest thereafter they start defending the nest and foraging for food.
