Germany, France and Switzerland are struggling to contain an invasion of Tapinoma magnum ants, a species deemed `virtually impossible to eliminate.

Originally found in the Mediterranean and North Africa, these tiny ants, measuring about 3mm, have formed super colonies, with hundreds of queens, throughout Europe.

Residents in affected areas report extensive damage to infrastructure as the ants eat through walls, pavements and cables, and complain of bites to children and pets. Local authorities have tried various methods to destroy the nests, but the ants continue to thrive, leading to power outages and internet disruptions.

Experts attribute the invasion to global warming, as these ants prefer hot climates. Despite their adaptability, entomologists note that they are most vulnerable in winter. But the challenge of eradicating them remains.•
