During the summer, when is the optimal time to treat fire ant mounds?

The optimal time to treat fire ant mounds is in the morning or evening because these times are cooler and more suitable for the ants' activity. Fire ants tend to forage and be most active during the cooler parts of the day, which includes early morning and late evening. During these times, the treatment can be more effective as ants are likely to be near the surface and more likely to come into contact with the pesticide.

Applying treatment during the heat of the day, such as midday or noon, when temperatures are higher, may cause the ants to retreat deeper into their mounds, reducing the effectiveness of the control methods. Similarly, treating late at night is not practical since fire ants are less active and visibility can be poor, making it harder to target the mounds effectively. By choosing morning or evening for treatment, pest control professionals can maximize the likelihood of successful control of fire ant populations.
