A raised bed is the perfect place for vegetables. The soil in it overheats faster, is loose, airy and provides good conditions for plants with regular watering. But this kind of environment also attracts ants.
They get into the structure easily because, unlike voles, they are not stopped even by the protective net at the bottom of the bed.
Although ants are not among the pests that eat vegetables directly, they create tunnels in the soil through which irrigation water quickly flows deep. The plants can then suffer from drought despite the fact that you water the bed regularly. If the ants undermine the root space, the plants relax, take in water and nutrients less well, and with more severe damage, they can wither and dry up.
Avoid chemicals in this case
You have to be careful with a raised bed, especially because we mostly grow edible plants in it. Chemical preparations against ants are not a suitable solution directly between vegetables and herbs. If the raised bed is next to a sidewalk or terrace, baits against ants can be used outside the growing area itself. In the soil between the plants, there are rather gentle procedures that do not kill the ants, but make their stay so uncomfortable that they move elsewhere.
