What time of day is considered best for treating Argentine ants?

The best time of day for treating Argentine ants is early morning. During this time, the temperatures are typically cooler, and the ants are more actively foraging. Treating when ants are foraging increases the likelihood that they will come into contact with the bait or treatment you apply, leading to more effective control of the infestation. Additionally, the cooler temperatures can help maintain the effectiveness of the bait, as excessive heat can reduce its efficacy.

In contrast, late afternoon may see declining ant activity as the temperature rises, while midday can be too hot, potentially driving the ants deeper into their nests and away from the treatment. Evening might find ants less active as they settle into their nests, reducing the chances of them encountering the bait.
