The reasons behind ant invasion in your home and what they reveal

Sweet bait with baking soda: this combination attracts and then neutralizes ants without toxicity.
Repellent spices: cinnamon, cloves or laurel form effective natural barriers.
Rigorous hygiene remains fundamental: airtight food storage, regular cleaning of sensitive areas and strict waste management.

When to call in an expert?
If the invasion persists despite your attempts, a professional will be able to identify the exact source of the problem, whether it's a hidden nest, moisture problems, or a particularly hardy species.

To conclude
Ants are not just stowaways. Their presence often reflects an imbalance in your home. Rather than systematically eliminating them, learn to decipher their message and adapt your environment to prevent their return.
