A STINKING species of super-ant is storming by means of Europe on a path to the UK.
The millions-strong mega-colonies have worn out energy provides and even roads as they overwhelm the bottom beneath complete cities.

The species, known as Tapinoma magnum, hails from the Med and North Africa – however has been pushing up by means of the continent.
They unfold quickly and set up supercolonies of as much as 20million throughout 60 acres that are “just about unimaginable” to eradicate.
There have been so many ants, you could not see the ground anymore

And anybody who dares squash a T. magnum is greeted by the stench of rancid butter.
The invaders hit headlines in Switzerland this week as officers in areas across the capital Zurich try and oust the pests.
The ants have additionally taken root in France – however Germany has suffered probably the most.
In Germany, the sleepy south-western city of Kehl has been swamped.
Locals reported watching the city’s pavements and curbs sinking because the earth was carted away by the bugs, inflicting havoc with the roads.
And a playground was compelled to shut after ants took over your entire space and turned it right into a nest.
Metropolis employees needed to jet sizzling water into the labyrinth to clean them out.
The broader state of Baden-Württemberg has suffered energy cuts and web outages after the bugs chomped by means of electrical cables.
T. magnum’s harmful energy comes from the sheer scale of their underground warrens and their tireless willpower to broaden.
Whereas most ant species organise just a few thousand employees round a single queen, T. magum clans comprise as much as 20million and a whole bunch of queens.
As an alternative of attacking each other, the smaller colonies merge collectively in alliance.
The British Pest Control Affiliation advised The Solar that the UK is in danger from the advancing campaign.
Particular person efforts by owners and gardeners cannot management an infestation

They defined the ants “unfold primarily by means of horticultural imports, particularly potted crops and bushes from the Mediterranean”.
They added: “If T. magnum had been to determine right here, it may turn out to be a nuisance.
“They type huge supercolonies, displace native species and may even trigger structural points by excavating underneath paving.”
Though the species has not marched into the UK but, a spokesperson for Defra stated the company “stays vigilant” to the menace.
The countryside round Zurich has been laid low with the ants since 2018.

Regardless of an almighty effort to clear them out, the ants stay “effectively established” in 4 areas.
In Winterthur, they blocked a billion-pound development mission after they settled precisely the place a multi-track railroad tunnel was deliberate.
Within the close by Oetwil an der Limmat area, one supercolony infested a complete five-hectare potato subject – about seven football pitches.
An area, Agnes Wirth, advised Swiss website SRF: “There have been so many ants, you could not see the ground anymore.”
However that’s dwarfed by the colony in Volketswil, on the opposite aspect of Zurich, the place an space the scale of 35 soccer pitches is teeming with the busy-body bugs.
The infestation is so huge that the native authority has been legally compelled to behave.
Katharina Weber of the Zurich Division of Building stated: “In areas with massive infestations, a coordinated method by specialists is required.

“This implies a plan is required, and particular pest controllers have to be deployed. These can goal the insecticide on the nests.”
Within the UK, DEFRA recommends that anybody who sees a non-native insect species takes a photograph and stories it.
Mike Fox, file supervisor for the Bees, Wasps and Ants Recording Society, stated: “So far as I do know, there are not any data of Tapinoma magnum turning into established within the UK however after all it may doable within the future.”
Niall Gallagher, the Technical Supervisor at British Pest Control Affiliation, stated they intently monitor pest species – together with Tapinoma magnum.
He advised The Solar: “Analysis on Tapinoma magnum supercolonies in Switzerland has discovered that these ants reside outdoor and may proceed to forage at temperatures as little as 6 levels through the winter months.
“Particular person efforts by owners and gardeners aren’t enough to successfully management an infestation, and particularly tailor-made pest management options are wanted to eradicate a colony.”
He suggest that anybody involved about an ant infestation contacts knowledgeable pest controller for assist.
Tapinoma magnum species
In response to the British Pest Management Affiliation, one among T. magnum’s most hanging traits is their procession behaviour.
These ants type conspicuous trails throughout pavements and up buildings, typically in massive, coordinated traces.
These trails are strengthened with pheromones and may span a number of metres, connecting completely different elements of their supercolony.
To the untrained eye, this may occasionally appear to be a really lively colony of frequent ants – however the sheer quantity and organised motion generally is a telltale signal of T. magnum.
In established infestations, these trails could even lead into buildings, throughout partitions or deep into pavements and backyard options.
If the species had been to determine right here, pest professionals would doubtless depend on a mix of bait gels (similar to indoxacarb or imidacloprid) and floor therapies, as was executed efficiently in Zurich, Switzerland.
As all the time, public consciousness and early reporting are important instruments in managing invasive pests.
Suppose you’ve seen one thing uncommon? Right here’s what to do:
- Don’t disturb the nest
- Take clear, close-up images of the ants and any distinctive behaviour (similar to path formation or massive aggregations)
- Report the sighting to the Non-native Species Secretariat through their web site
