The answer to 'ant season' is that ants are typically most active during the warmer months of the year, typically from late spring through early fall. This is when ants emerge from their nests to forage for food and expand their colonies. Ant activity tends to peak in the summer when temperatures are highest.
Ants can become a nuisance in and around the home during this time, as they may enter in search of food or moisture. Homeowners may notice more ant activity inside the home, as well as around the perimeter and in the yard. Certain ant species, like carpenter ants, can even cause structural damage to homes if their nests are located in the walls or foundation.
