The return of ants is a frequent phenomenon from the first heat. But the cause is sometimes much less obvious than it seems and often goes unnoticed.
With the arrival of good weather, ants become much more active around homes. Even houses that seemed spared until now may see a few scouts appear in the kitchen, the bathroom or near the windows. A frequent phenomenon at the start of summer, when colonies take advantage of the rise in temperatures to intensify their activities.
When many people see ants in their home, they immediately think of sugar. It is true that these insects like sweet foods and know how to quickly locate a food source. However, this explanation is not always enough to understand their presence. In some cases, even an immaculate house can attract their attention.
The reason often lies elsewhere: ants are also actively looking for water. When temperatures rise and the soil dries out, the workers search for moisture points to supply the colony. A saucer under a flower pot, a pet bowl left outside, a regularly watered terrace or even a damp sponge can become real ant magnets. Contrary to popular belief, it is not always food that attracts them first.
This quest for water plays an essential role in the survival of the colony. Ants need it to regulate the humidity of the nest and feed the larvae. In hot periods, they increase their explorations in order to identify the best available resources. When a scout discovers an interesting watering hole, she leaves behind a chemical trail that her peers can follow. This is often how a few individuals end up being joined by several dozen others.
To limit the risks, specialists therefore recommend monitoring sources of humidity located near the house. Regularly emptying the saucers of flower pots, avoiding stagnant water on terraces or balconies and frequently renewing the water in bowls can help reduce their presence. These simple actions do not replace good general hygiene, but they allow you to act on a factor that is often neglected. Because at the start of summer, ants are not only looking for a little sugar: they are also thirsty.
