Prompt waste disposal is advisable in any case, as rubbish that is only left in plastic bags on the doorstep, for example, always attracts vermin such as ants. This is even more true in southern regions of Europe than in central Europe.
But ants also become active very quickly in the house - and especially in the kitchen - if any food residues are not removed thoroughly enough. However, ants are part of the normal appearance of any rural finca, even with the most scrupulous cleaning. However, should the problem become too persistent, please contact your local contact person immediately so that further measures can be taken.
