The answer to 'ant control season' is that ants are a year-round pest, but their activity tends to peak in the spring and summer months. Ants become more active as the weather warms up, searching for food and nesting sites both inside and outside the home.
The best time to focus on ant control is in the early spring, before the ants have fully established their colonies. This is when they are more vulnerable and the best time to implement preventative measures and treatments to keep them at bay throughout the warmer months.
