Ants become significantly more active during the warmer months as colonies reach their largest size and worker ants search for food to support the nest. The ants you’re seeing are worker ants that bring food back to the colony. Think of sprays as a temporary solution and bait traps as the long-term solution. Rather than killing ants immediately, they allow worker ants to carry bait back to the nest where it’s shared throughout the colony. People often worry when they see more ants after placing bait traps, but that’s actually a sign they’re working.
